It's not always the head gasket. If you're not losing coolant, it's not the head gasket. If a simple test to see if exhaust gasses are in the coolant is negative, it's not the head gasket. It is a misfire. Could be a bad plug. Could be a bad injector. Or anything else that might cause a misfire.
That's just scary how long that car rattles. I cringe at the 1 to 2 second days when decides to startup for that long. The 3 second startups on those days seems to throw the check engine light and that's what's really alarming to me. This month summer taxes and head gasket kit or maybe head gasket and specific crankshaft, VVTi and oil seal gaskets.
04-09 was the best prius models made to date. Toyota didn't skimp on anything that matters on those units. The prius community agrees that for the 3rd gen who ever was in charge of QC went on vacation that day. They later returned from break for the 16-23 models
@@tydengr Man, I've done barely any serious maintenance on my 2013 and I'm at ~285K miles. Only rear pads due to the lower passenger side caliper pin seizing, drivers since inner tie rod and drivers side hood hinge with the later most likely due to coyote, doe and semi trailer tire impacts albeit really slow. I have had the EGR, Intake and PCV Valve circuits maintenance cleaning and PCV Valve swapped more than once though is like a consumable like the others. Everything else is OG and running mid 40's to mid 50's MPG. Amazing how these can go and is totally worth the head gasket swap. I'm amazed how long this is going with the 1 to 2 second rattle with now my 3rd check engine code thrown when does the 3 second rattle on startup. Almost totally awesome like Gasket Masters! Can't ask for more IMO.
These guys are legit and do amazing work. The owner is really nice and knows exactly what he is talking about. He replaced a 2010 Toyota Prius head gasket under 3 hours at my house. You can’t get any better service and expertise than these guys. If your engine is knocking don’t wait just call these guys!
There appear to be only three locations nationwide... not close enough to northern Arizona to help me, but this wouldn't be my first head gasket in the last half century.
Thanks Walt. You guys did a fantastic job on my 2010 Toyota Prius. Thanks for coming down and making time to SoCal and doing the rebuilt for me. The engine runs great and we put good mileage into it so far. I can definitely say that we are driving with ease knowing the car won't stop in the middle of the freeway.
I got very lucky as there was a cancellation and the guy in the video is here right now and going to take care of it. I’m very grateful and thankful 🙏🏽
Hey I have a 2015 Toyota Prius and I heard this noise a couple of times over the years. My car doesn’t make this noise every time I start the car last time I heard this noise from my car was two months ago before that was a year ago so it makes this noise once a year should I get my head gasket changed? Please let me know before anything happens to my engine I would like to change or fix whatever I have to fix
Wait! What happened to your older videos with the complete 2ZR Prius head gasket replacements? Those were awesome, and I was just about to get out there in my driveway and use them to do my own vehicle .... but the videos are gone. Did something happen? Please tell me they are not lost forever?
I have same problem in my 2010 Prius (120k miles) since last year. It happened 4-5 times maybe. No losses of coolant. I found that it could also be intake manifold problem. Toyota released TSB with that problem. If it is not a every start problem you suggest to replace gasket? Greetings from Poland.
Wow, so true. I heard that noise and drove 3k or so miles and one day same exact thing happened to my prius. 2013 yr. Too late for me...lol. how much does it cost to replace the head gasket.??? Parts and labor?
I called him, so polite, professional behavior and straightforward. He told me this is the price final for everything. So that is how I need to know my car's repair cost to decide. I also used their videos and replaced one Prius's head gasket myself, but I do not recommend you to do it as I did if you are not very dedicated, have a garage, and have good knowledge and skill to work with engines. It took me 2 days and nights till morning to finish the project. So, hard job if you are doing it alone and for the first time.
If the cold coolant level is changing, Better Call Saul. No, wait... do a block test (which is what the mechanic will hopefully do. Quick, cheap if DIY, not too expensive if a pro does it. Better than calling Saul.
My buddy just sent his kid's 2010 Prius ( the kid adores the car and was heartbroken when the engine noises started a few days ago!) to this guys shop for a head gasket, and it was fixed the same day! Amazingly fast repairs and at a modest cost too, as far as engine work goes anyway. Highly recommend this guy! This was the shop near Berkeley CA.
@@joeconway982 $1450 Included totally cleaning the EGR system as well as a new head gasket, new coolant and new oil too. I am assuming new head bolts too.
My ladies 2015 Prius v is making these same symptoms it’s not very often at all very random but it’s started with the clunking noise a half dozen times and now watching your video I believe I have the same problem
Be aware a bad head gasket is not always the cause of start-up clanking and shaking. If the car is "short moved" and the engine tries to start just before the system is turned off residual fuel in the intake does wonky things that shake the car and sound like gremlins are hammering on the engine. Let it sit a while and all is well. It isn't a head gasket leak until tests point clearly to it. Just go in and pull the plugs - oh, yeah... remove the wiper shelf first. Jeez. Probably better to do what the Car Care Nut describes in "How to Check for a Bad Head Gasket on Toyota and Lexus Engines"
Sounds like the 2010-15 have more head gasket problems than GEN 2. Our local Prius experts, Escondido Auto Pros, like to replace the engine on GEN 2s instead of replacing the head gasket.
Thank you for this video. Unfortunately I have to change the engine because it's been doing it for so long and I'm losing a lot of oil but at least I know why it was doing it now
I believe this is the sound I heard yesterday and the last time I heard it was almost a year ago, and before that maybe a year before that just say I wasn’t able to fix this now and I don’t hear any of the rattle rumble for another year or two how much damage could it possibly be doing? Just a hypothetical general question Thx
Following @gasket masters, I have the same thing on a 2011 Toyota Auris 2ZR engine, in the last 4 years once a year the engine rattles and shakes for a few seconds, now it has 313000 km, (I did all the oil change only at Toyota at the right time) tonight I just left the car to the Toyota dealership for diagnostics, I am in Romania! Thank you for the videos. Cheers!
I have a 2015 Auris (European model, pretty much the same powertrain as 3rd gen Prius). Do you know if Toyota has made any improvements to the head gasket in later models (2014-2015) to prevent these failures or is this issue only with earlier models (2010-2013)?
I just paid 10k cash on a 2012 200h YESTERDAY from a car lot... and I get it home to hear a DEMON shudder... wtf do I do? I live nowhere near CA(in ky).. bought this as a work vehicle to drive to Texas(oil fields) as I FINALLY just got called back to work, and now I am stranded after spending 10k cash for a "RELIABLE" vehicle, and am going to miss out on a 6figure job.... did I mention my wife and I have 8 kids? Why are people so damn shitty, bro!?
I've had this problem for 135,000 miles now. A fix for me I've found that if once I start the vehicle I let it fully warm up then It does not happen. But if I start the vehicle for just a few seconds to a few minutes then leave over night it shakes like mad!!! So if this is happening to you try to always fully warm up your car each and every journey. I got the car at 100k and soon after I discovered this problem. It was only after 20k or so I noticed that it only happens after I start the car and not allow to fully warm up then leave for some time. The car is now at 238,000 miles
That's a known problem, not related to blown gaskets. No permanent solution (as far as I know). Just prevent starting the engine for very short periods (use EV mode with heating turned of).
I know this video was made a couple of years ago, but I was hoping you could tell me if you remember how many miles were on the vehicle. Great tutorial by the way. Keep up the good work!!!!
My 2012 Prius v was having this issue before and after replacing the head gasket. It's only when I started running marvel mystery oil in the engine and adding seafoam to it. Did it stop? It does still give the occasional shutter on start real quick, but that is extremely rare and usually goes away within a few combustion cycles and doesn't last for minutes like it used to the best is we could tell is the PCV valve head failed and just by design? For some reason the oil was splashing on the PCV valve inlet in the crankcase itself. So my issue was actually getting too much oil in the engine. That is part of the reason why these engines end up burning oil as well because of leaky PCV valves and usually even the new valves are kind of terrible and still leak but not as much as an old worn out dirty crappy PCV valve it's not always your head gasket in my car has over 408,000 mi. I put a new head gasket on it at 263,000 mi and it still continued to do that. I took it back to the Toyota dealership that had a one-year unlimited mileage warranty. They checked it and said that they couldn't actually find anything wrong with it and that was back in 2020. It's been over 2 and 1/2 years and over 140,000 mi and the car is still running fine except for it's an oil burner now.
The EGR valve sticks open and allows too much unmetered air into the engine essentially choking it which makes this rattle noise and all of that extra pressure in the combustion chamber will blow the head gasket. These guys are not being entirely honest about this, there is more than one way to blow that head gasket. Generally if coolant is leaking into a cylinder you will get the white smoke out the tail pipe and you will smell it. There is also and EGR motor ecu update as well as updated air intake manifold design for this car as well as just simply replacing the egr valve first to save some time and money. Like you said you replaced the head gasket and still have the same problem, had you either tried for the software update first, then replace EGR valve - or clean it, then new air intake manifold - although I heard that sometimes that does not work either, those should solve the problem before going all of the way to replacing the head gasket and still possibly having the problem. It could just be that the head gasket is pooched from being faulty, but the EGR problems are also well know on these cars and as the saying goes, "start with the cheapest thing first." Take care, AC
How often does this happen? I`ve heard that the ct200h is one of the most reliable cars on the market. Like they can do hundred thousand miles without any engine/transmission issues. And after I`ve read it on several different forums I pulled the trigger and got a 2018 model for myself. A week ago or so I found this movie and several other examples on YT. Is it a very common issue? Cheers!
You can avoid this by cleaning EGR and it's also important to change oil and filter annually. I used to clean EGR of my CT200h once in every two years and no rough idles or knocking sounds (in the winter when engine's cold some knocking for 5 seconds, but it's pretty much normal with these engines). Also check your coolant and oil level regularly. If you're losing coolant, it may be necessary to do head gasket repair.
Mine shakes on take off from a stop. Then it smooths out. I put new coils and plugs which help but it still shakes on take off from a stop. It feels like it is from under the car to me.
My 2010 Prius did this about a year ago but has not done it since until last month. It does not do it every time it starts, just now and then. I have no loss of coolant and no discoloration of the oil. When it does knock on start up it clears itself up in about 30 seconds. I'm just wondering if you would reply to this and let me know with your experience if this sounds like what you are showing, a head gasket problem, or if you would direct me to look at something else. Thanks
2011 Prius 283,000 miles. What I determined my cause was my oil. I run Mobil 1 0-20 for 10,000 miles. No issues ,only about 1/2 quart missing when changing. Each time this happened I realized my car had sat for over a day or so usually a weekend . I noticed each time the oil was getting at the end cycle of 10,000 miles, Extreme cold, and bargain gas. The last time it happened was 1 month ago and it wouldn’t stop, I put it in neutral and it stopped. I finally did the oil change that evening and it next morning it was 25 degrees started just fine. I finally changed the plugs this weekend with NGK plugs, I removed the OEM Denso plugs to my surprised they looked amazing! So far so good. I agree with man making this video , but I liken the cause for some os us to be poor oil condition and poor gas causing a vapor issue in the head. Just my 2 cents.
Great video to watch to motivate me to get the head gasket changed. Just threw my third check engine code, though I reset the day after does. Still scary only rattling for 3 seconds which seems to trip the code. 1 to 2 second doesn't seem to. Odd is how some days does and others doesn't. Seems like hotter humid or flat out rainy days.
If you turn car on and turn off before the I.C.E shuts down it will cause it to rattle at next start up. This especially happens if you are just moving your car in the driveway and I.C.E kicks on while moving. Always wait until engine turns off before turning car off. This should solve your issue. Has something to do with condensation build up in the engine if the engine is not able to complete its warm up cycle. Happened to me once or twice and this is what someone explained to me. I have followed this advice and it has never happened again in over 240k. My car is 2013 with 343k on it and runs like new. I bought it used with 109k If your car runs well, you should do what I and many others do to avoid head gasket failure. Change the ICE water pump and thermostat if your car has over 140k as preventive maintenance as water pump failure is a major cause of gasket failure, from overheating . Also get the EGR cooler and EGR valve cleaned every 100k (new water pump/thermostat and coolant every 100k to 150k), as this contributes to head gasket. This is much cheaper than head gasket replacement and very easy to DIY, using RU-vid vids. Again I have 343k on my car and no issues with head gasket.
@@vikings7683 Since the extended service contract ran out at I think 150K or maybe later, I hadn't performed the Intake, EGR or PCV Valve circuit maintenance so is most likely at fault where I'm guessing the PCV Valve being bad and I overfilled the oil the last oil change prior before going on a 1,000 mile road trip where I also added a bottle of Techron in each of two full gas tanks after getting home. Did stop and go city driving with my Mom shopping all day and am thinking all that combined to my first check engine light and feeling the rattle and vibration when I filled up for gas the first time and the engine was already warmed, so I just drove off. Once the ICE kicked in while barely moving... had the first experience. Would only rattle for about 1-2 seconds, though I had a second warmed up engine experience where the engine didn't kick on until I started driving pulling out of being parked on an steep incline where wondering if maybe the oil overfill issue also contributed. That also threw a check engine light. After that, I made certain to press the gas peddle after startup to assure the engine started and cleared any condensation or coolant prior to driving. I also started to vent my coolant reservoir cap after driving almost routinely and that seemed to reduce the occurrence. About two months after that started, I had the first not moving experience which was the 3rd check engine light that came on after sitting from driving for about an hour on the freeway with a little city driving afterwards. I'm at ~285K, so glad for what little additional maintenance I performed, lasted as long as did. I think also might have contributed was doing the 100% engine radiator block last summer and all winter until in May when I had the first check engine light come on. I never noticed the engine temp going over 205F. Though thinking over 196 probably wasn't so good when did. So far all stock parts post extended service unless something might have been covered under warranty or recall. 2013 Prius model two and even with the situation, was still reliably getting 45 to 55MPG. I received the Toyota Genuine Engine Gasket Kit to assure I have all the gaskets and am waiting to get a Toyota 12V battery since after sitting, that battery was found at 4.2V which might have restored to 1/3 the CCA using a Hobby Charger with 8S, 10S and 12S charging and then the BatteryMINDer Plus. I also ordered the SAE connectors and outer surface plate so can keep on a tender when not using one. I also plan to maybe do the Berrymans B12 piston soak prior to disassembly and then a Wynns Air Intake Induction Foam piston soak once the head is removed. Was only consuming ~3/4 qt per ~5,000 miles, so not that bad.
Oh and I'm going to get the Fel-Pro head gasket just to be safe and save the Toyota one for later potential machining needs in the future. @@vikings7683
@@jafinch78 Should have bought the Fel-pro gasket kit instead of Toyotas . After all if Toyotas head gaskets were any good for the Gen 3 , people would not be having these issues. While I do agree on buying OE items, gaskets is one place I would always trust Fel-Pro gaskets over OEM for any car.
My 2012 Lexus CT200h 180k miles have the same problem, that’s Gasket leaking. They charged me $2500 to fix that. Now 215k Miles, it’s still running good. But I worry after fix Gasket, how last long my car can run? Because I really my car, I have a plan to replacement all shocks and wrap a new color for it.
Great advice, I just did my head gasket 500 miles ago and it threw #1 rod this morning. Guess it got weak where I waited to do the job....Now I am getting a used engine and I will probably do change the head gasket to a Fel-Pro before it goes in.
The weakness is not in the gasket so much as that the head verrrry gradually lifts near the middle over the years. I agree with @uzomad - stay with the gasket on the engine or get one from the dealer (a sad number of counterfeits have worked their way into the retail market supply chain.)
they quoted me $6300 for my 2010, and$4600. from a local mechanic, we freaked, especially being close to 70yrs old, and living in the San Diego area living on SSI, we simply "Did Not" have the $, nor any way to acquire that type of dealer rip-off amount, that badly shocked us, as we lost our trust in the dealers, and having had No other Choice but to simply add Blue Devil, and for the past 2yrs we've had absolutely No Issues "At All", and if i really had no other option, i have no other choice but to buy a low Mileage Motor from a reputable Auto Wrecker, for around $1K and have the motor replaced...and what scares me just as bad is when a supposedly reputable outfit will not give a general price approximation area, that too raises the red flags...thanks for letting me vent! Blessings to all those stuck in the Gen-3 Pruis that should have been recalled!!!
If you don't have the money, I put a can of KSEAL head gasket repair in coolant. That was 2 years ago. It runs perfect now. I was told it would plug up water passages and every other problem. Nothing but problem eliminated. There is no doubt it is a head gasket issues. There is an alternative. If you have the money, fix it the right way. I'm glad I was told about KSEAL. You will be pleasantly surprised.
Can the head gasket still be replaced if I’ve been using head gasket sealant for the last 3k miles(used it twice)? No shake at the moment but seemed to have been the head gasket since it was violent shaking at start up. It’s a 2010 w 240K miles. Thanks
Would you recommend going Felpro head gasket or is there a revised oem toyota gasket? They say 2014+ ct200h fixed the headgasket issue but from what I see its the same part number as the prefacelift
Ive researched wnd found that my card issue is most likely my egr and egr cooler clogged up really bad. Mine will rattle a little bit at start up then goes away after a second. I also dont have any coolant what so ever in my oil sooo?
These guys are doing great job, they have changed my car's head gasket after my car got blown gasket,,,,my advice to you, if you hear that noise in your car, just call these guys, they will fix it right away with very good price and short time.
@@Orrlur RepairPal says, "The average cost for a Toyota Prius Head Gasket Replacement is between $1,956 and $2,325." "parts are priced between $577 and $585" As a hopeless DIYer I would do it myself, but I would take the head to a machine shop for inspection.
It is a common problem in 2010-2014 Prius. Our 2014 has about 210k miles on it so I'm keeping an eye out for dropping coolant levels. A piece of blue tape I put on the reservoir has a reference pencil mark on it.
Hi. I need help please. My 2010 prius, 97k miles , rattles on cold start when converting to engine. Rattle lasts for about 20 secs and then settles. Spent lot of money.. changed EGR, spark plugs, cleaned manifold. But made no difference. I keep a track of coolant level. There has been no coolant loss at all since last 5 months.. My mech says it can be broken spring of a worn flywheel or clutch damper. As there is no drop in coolant level, could it be possible that its not the head gasket? Does flywheel or damper noise present this way? Also. I notice that during start while still on battery, if I put the mode in D ( with brake applied) the rattling doesn't happen when the engine kicks, as long as gear is in D. The rattling happens when in P mode only and not when in D mode . Any idea what this could be ? Any help is appreciated.thanks
Question! I had an oil leak a couple months ago and replaced oil pressure gauge where it was leaking and the head gasket as well, it needed one. Did the trick, no more problems on that front. Today I had the 1st cylinder misfiring, code P0301. I see no coolant in the oil so I think the gaskets fine. I switched the 1st and 4th ignition coil to see if it was a spark plug problem. The engine light went off, no further codes on my OBD2 scanner and drives fine with no more shaking upon startup. Could that have just been a bad connection or something? Everything seemed to have been tight upon taking it apart.
I have the same problem started yesterday with the shaking the the clanking noise I replace the spark plugs I clean the intake manifold I cleaned up the cooler all the passages with a wire it looks really clean now . I cleaned the injectors put new o rings on the injectors .still got the same clanking noise and it shakes a lot .so I turn it off I'm still looking for the problem is giving me a P0301 code I replace the coils from one side to the other still the same clanking noise Its loud sounds like the motor is gonna brake....the car is not wasting water . I see no vapor coming out of tail pipe .. I looked inside the Pistons they don't look ..no steam or water going in there. Coolant level is good I still don't know what's wrong with it maybe the EGR is bad but I disconnected and it doesn't make any difference..I'll be testing the coils tomorrow .. cars has 184 thousand. I know I need to replace the head gasket anyway
Clean egr pipe with cobra pipe cleaner long sturdy metal with black nylon brush from Walmart. mine hv same prob n cleaning egr pipe stop the rattle cold start since
I gave them a call to have my 2012 ct200h head gasket replaced because my car shakes and rattles every start up and it goes away after a few seconds. I had my appointment reserved and they showed up on time. It took them a few hours to replace the headgasket and now my car is back and running real good! Thanks Gasket master!
I have three replaced by Gasket Masters ..waiting on their reply one of them Failed .I am waiting on a reply It’s been 2 1/2 weeks Prius is still sitting there misfire on the cylinder still Walt I know you’re reading this you can’t leave us hanging we’re not just gonna disappear please follow through and get this warrantee done thank you.

after 45 k miles, my PriviusV engine starting do this. I traded in for other car. Bad design should recall. for may year, I wonder what caused the issue, now I know
Hi prius rooks forward and back when in park and engine turns on also heat a rattle when accelerating slow on a hill .Toyota dealer says no misfire or mounts issues they “checked” it he says it’s normal for age 2006 prius 196k miles engine also slight wobble when in drive with foot on brake please HELP !!
question I have a 2010 prius 80k miles one morning I had that horrible shake and noise but it never happen again can you tell me the reason?? thanks so much for the videos.
Hi, I'm from France and my engine exaclty the same problème. I would like to fix it by myself but no body can help me tu find the référence of the parts a have to change. can you help me please ? if you have a list and references of the part and a must be change ( head gasket, cylinder head stud ...) it should be fantastic. Thank for your vidéo.
People still claim gas and Diesel engines will last forever and they hate the idea of electric vehicles, everything made by human beings tends to breakdown!!!
Very good description of prius misfiring vibration shaking rattling causes. I'm nearly coming to the decision to change the headgasket if the waterpump change doesn't fix it.
They blow because the EGR cooler becomes plugged and also the PVC valve eventually clogs up. Proper maintance is a must. The new head gasket design Fel-Pro is a must
I've been developing a theory that the reason these fail so much is the constant temperature changes. In a regular car the engine stays on for a drive cycle, in a prius its constantly on and off with sometimes 5-10min intervals. That interval has got to be enough for the hot coolant to come down in temp 10-20. With temperature fluctuations parts expand and contract, and an aluminum head/block will do so at a different rate to the steel gasket, granted at 20° difference its not much but multiply that by thousands per day its gotta have some kind of effect.
My 2010 Prius started doing that rattling noise this morning it’s not as loud and it comes up when starting the engine. How much do you guys charge for head gasket replacement?
This is SO useful to hear!! We have had the same exact symptoms on our 2010. And we have ALSO had a very small oil leak happening since not long after we bought the Prius in 2010. But all that was dismissed. So now I am going to be tooling up and watching your head gasket videos until I have every step memorized. We live in NY State otherwise I would be giving you a call. Your videos are among the very best on RU-vid (so well shot and explained). Keep doing them, please. And thank you.
I’ve had a similar experience with my 2012 Prius. When I researched it, it appears that when you shut the engine off right after it starts (like when you’re repositioning the car in your driveway), there can accumulate unburned fuel. The next time you start the car it will rattle a little. I’ve avoided it happening again by insuring that when I repositioning the car and the engine kicks on, I make sure to run the engine for several minutes before turning the car off. I’ve got 135,000 miles on mine. I’m curious as to when the head gasket should be changed as a maintenance item. Should we insure the head gasket is replaced at 100,000, 150,000, 200,000 to prevent this type of failure?
Happened a few times on my 2012 and turned it off immediately . Began using premium chevron fuel and the noise never came back. Toyota sells a fuel additive as well to clean up the fuel system.
Gasket Masters, My daughter's prius has this shacking/rattling going on for the first few seconds when she puts the car in gear (engine cuts on). We pull the P0300, P0301 and P0302 codes for a missfire. Is this the same problem?
