Honda Odyssey Pilot 3.5L Engine Rattle 

I'm going throught the exact same thing now. Found this video. And what this man is saying is exactly what the mechanic who saw my vehicle said. Amazing! Thank you. You've earned my trust.

Great video. My 07 Accord is doing the exact same thing. My mechanic of the last 30 years was thinking my engine is gone. I told him about this and he's going to take the cover off and see what he finds. We shall see. Thanks. UPDATE******* This was exactly what the problem was. Thanks for posting very much. 👍

Great posting! I was about to take apart my valve cover chasing what I thought was a valve train problem, then after seeing this, I discovered my blown tensioner. Thank you!

Great show and tell video. My 06 started to rattle 6 weeks ago and it has driven me nuts. I thought it was my exhaust falling apart. Thanks so much! And now, to save some money.

Thank you for your Video! My friend who is a mechanic told me I needed a new engine because the sound was already a bad engine/valves. I reasearched the issue and found your video. The sound of a bad timing belt tentionair was similar to my 2013 Odyssey. I myself bought the timming belt tentionair kit and had my mechanic/friend replace all parts. When he was working on my car he was still telling me where to look for engines because the work he was doing on replacing the tentionair was not going to work. When all was set and done, my friend told me to start the car. THE SOUND WENT AWAY. MY VAN DID NO LONGER SOUNDED LIKE A MOTORCYCLE. My machanic friend apologized about 100 times for giving me a bad diagnostic. Thank you again for your video THE CAR DOCTOR. YOU SAVE ME A LOT OF MONEY.

My 2008 Odyssey is doing this and I was for sure it was a rod knocking or a bad valve. I really hope this is the problem and it sounds like exactly like it does in the video so hopefully this is my problem and I don't have to tear my motor apart! Thank you so much for this video you are a saint!

Went to two different garages. One told me the sounds the engine was making was from running it low on oil. The other said sell it ASAP because the motor was junk. So I watched your video and your honda odyssey sounded like mine. So I took it into my Honda dealer. Got the belt and the belt tensioner replaced and it sounds like a new van again. I very much appreciate your videos. Saved me a lot of time and money. Thank you

Yep, my wife’s 06 Ody tensioner went bad after a month replacing the timing belt. Glad I kept the original Honda tensioner. I was sweating bullets thinking the engine was shot! This was my first timing belt replacement on a V6. Replaced the tensioner with no further noise or issues 👍

Glad to hear you are coping well with the earthquake.I remember one in about 1964 which caused a tidal wave and flood damage in Port Alberni on Vancouver Island. We are on a Fault. Interesting vid on the belt tensioner.

just from your videos i can tell you run a great shop,glad you guys are ok!

Glad you're doin good after the quake! Thanks for the great video Tim.

Glad to hear all is well with you and yours. Diagnosis was spot on.

Good job sir. Keep it going. Praying for your and everyone's safety and hopefully does not happen again.

Hey Tim, I'm happy that you and your family are safe and we'll. You are in my prayers and thoughts. Thumbs up to you and your video. I truly hope you have a blessed Holiday season.

So glad you guys are good, thank you for the valuable information.

Tim Glad you and family are all ok. You were the flrst thing I thought of when I heard the news. Logged on and saw your tour of the spilled shelves. Carry on and safe holidays! Mike from NY

I purchased a genuine Honda OEM Made in Japan tensioner as a spare for my 2010 Pilot. It's astonishing how many repair facilities will try to upsell the repairs by telling a potential customer their engine is shot when it isn't. Thanks for the great info!

This is a great video, Tim, with logical procedure and process. As soon as I heard one of these, the tensioner was my first thought, the sound and tempo is pretty unmistakable, even on different car lines, and number of cylinders, once you have heard it, But I'm not afraid to see what others have found for solutions This is usually caused by being in a hurry to reinstall a good hydraulic tensioner, and compressing it too fast, too much pressure, in the wrong position, or dirt on the tensioner shaft Kudos and God Bless!

Glad to see you and your family are safe.

Great video Tim. You are a gentleman.

Thanks for your video. Gives me something to discuss with my dealer.

Been making noise for a while before that point. Good diag.

The first TB job I did on my own 08 Ody I used genuine Honda parts. This was at 100K, and back in 2013. at 185K the Honda replacement tensioner started to make this noise, though nowhere near what your van sounded like. I had to go in about 25K early and do the TB/WP job. I now use the Aisin kit when I do these jobs for other people. The bearings are OE Koyo bearings, the OE water pump is actually made by Aisin, and the Aisin kit belt is a Mitsuboshi, which is what the original Honda belt was. It's pretty much an OE kit for a fraction of the cost. Aisin is the way to go on these cars.

Great vid as always, thanks Tim!

Tim,excellent video thanks for sharing. Artie 👍👍👍

Aloha Tim. My sincere apologies for not getting our prayers to you, the whole family and especially to those in need much sooner. You're all in our deepest and strongest prayers. You've got the whole group (58 people) yelling out prayers for ya.

This was a really informational video.

Thank you my friend from Tijuana Mexico

Great info! Now I see why you're the car doctor ;)

great video and glad no one was hurt in the earthquake.

Glad your safe and okay tim

Great vid, I have the exact same problem, and I’m thinking about doing it myself. So the parts that you replaced were; the cylinder, water pump and the belt? Thanks!

Thank you so much for this detailed video. I had several ppl tell me I'm wrong about it being a tensioner. They all said it was a bad engine bearing and I was screwed. Nearly $200 and nothing I could do. This van is my way out of homelessness... Getting me too and from work and back to a shelter. I wish we had you here in Oklahoma!!!! Thank sir and God bless you.

hey man, thanks for being so through. Great video! Not sure my issue is the same as this but I found the video very helpful never the less

Glad, Alaskans, and your family are ok Doctor.

First thing, Blessings Tim. Great vid 👍 While watching your video, I notice you had a shim. How crucial is it, and where does it go? The car didn’t have one when removing the parts, and curious to as why it didn’t come in the TB kit. I did the first TB and kit on the vehicle. After starting it for a minute and topping off the radiator and power steering pump, I went to turn on the heater on and the rpm’s dropped really low. Turned it off and notice my rpm’s are lower than it usually is at 1000 rpm’s. Would like to add the shim when I go back in there tomorrow to figure out why it’s dropping.

Thank you sir for the informative video👍🏼

Oh Yeah, almost forgot .. Another awesome video Bruddah!

Great video! My 2008 Honda Accord is making the same noise just not as loud “yet” lol. Can you please tell me what exactly you replaced. So I can buy those items.

Good video I just fix a 2011 account same engine same problem,, lots of noise

What abouy if it doesnt move at all?i just removed one tonight and it doesnt push in at all and this car sounded insane like every valve was gone. But should it be tight solid or have little wiggle?

Very very informative video. I have an 04 odyssey and was wondering how many miles is on this one? Looks like the quake ruffled your hat crooked a touch 🤓 Again great video 👍

You did great! Thanks

Mine is a 2012 Honda pilot with 75,000 miles and no sign of any leakage. Making the same noise so would this be covered under my extended warranty?

Great video! I own a 2007 Honda ridgeline that when purchased had 125000 miles. 3.5 liter engine. I changed all those components asap since these are "interference" engines. Don't want to do a complete engine overhaul or replacement! How many miles on that vehicle??

Pretty sure my tensioner actuator is shot. Belt, pump and pulleys were replaced, but not the actuator. Curious if it can be replaced without popping the belt cover. Replacement part pics show a "grenade pin" that looks to keep the piston compressed while installing, so not sure.

Would that cause a battery light to turn on inside that dash?

The t belt water pump kits I put in those j series engines is the aisin. The other kits have Chinese pumps that will leak in a year or two.

Nice Video,Thx...

The leaking oil was the tip off, good diagnosis.

Great Video

Thank you nice video

Was there a check engine light on?? By chance?? Thank you

Good One Glad your good

Tim i have the same vehicle and problem. What should I be paying for this so I'm not over charged? How many hours does the book say? Thanks

Thank You for sharing

I wouldn't recommend that DIYers lean over a rotating rotor - if it catches your shirt, your not going to have a nice day.

Nice good thank you

question! its the pilot use same engine as the odyssey?

We are having this like rattling noise in our 2017 Honda Odyssey with 90,000 miles 5 years old bought it brand new off the lot and for some reason the Odyssey makes this rattling sound. It also says check parking sensor system but *knock on wood* never has given us a check engine light when the van rattles and we’ve never had to replace the ocm that I know off the only time the check engine light came on was when our ignition coils went out that was the only time the check engine light came on. Got it replaced van runs fine the parking sensors though don’t we have this light on that says check parking sensor system. goes away and it stays on then beeps after like 20 minutes what do you think that means?

another time i had a weird erratic noise like a bad idler bearing might make turned out to be the serpentine belt....the crank pulley had the belt off by two rows and the noise the belt ribs made while going over the misaligned pulley and ribs made the sound.....sounded like someone was erratically shaking a 10mm bolt in a medicine bottle.....realigned the belt and noise was gone.....never would have thought a belt would nake such a noise.

Thank you.

Mine is making the same noise, only it’s a slightly lower pitch rattle/knock. Could it be the timing belt tensioner? I have a 2011

How many miles on this engine, and what happens if Timing Belt fails? I know Toyota V6 has timing chain.

seen this on Subaru also...tim on the gates kits they give you a china tensioner that needs to be blead crazy!

My tensioner has just recently been replaced by the Honda dealership. So my problem doesn't seem to be tensioner, what else can it be?

I have a 2009 Pilot and the previous owner changed the TB at 102k in '16 (verified VIN at Honda dealer) and now I'm at 175k and I have this rattle but only when the engine is cold, then it sounds normal after warming up. Im wondering if I should go ahead and have the TB kit changed now or wait until the interval 🤔

What year is that and how many miles has, that info is very important, I have a 2016 pilot 3.5 n feel worried about that

Cool I get a few of these in from time to time!

Thanks buddy

Ahat rpm was that noise taken at? Sounded and looked like above idle speed.

Thank you sooo much! That was it......

Do you have to undo the crank bolt in order to replace the timing belt tensioner? Or is it just a tensioner 2 bolts swap out then pull the grenade pin 📌 to set tension? Thanks sir

At 4:12 you almost gave me a heart attack!!!! If those wheel studs grabbed that long-sleeve work shirt, it could wind you up and give you a fatal thrashing. Happens fast, like a lathe accident. Please be careful.

this is whats happening to may car and i need this help they tell me to replace my engine with out no diagnostics but i need a real mechanic ugh

7:00 "There's you problem Lady!"

same issue I'm having with a 2013 Honda Odyssey, going to replace timing belt and the whole thing :)

I just had my motor replaced and it's making the same noise, I feel like if I pay 4000 the motor shouldn't be making any noise, I paid 1500 upfront but I haven't given the other 2500 should I tell him to keep it until the noise is completely gone?

Aisin or OEM Honda are your best kits for anyone doing these repairs.

My 08 odyssey just started doing this

my noisewas such that prior to inspection i was concerned a camsprocket was loose and rattling against the cover

I got same issues right now with 2009 pilot. My company auto mechanic said my engine is gone. But looks like I don't have to salvage my pilot after all.

Well I changed the tensioner and belt. That noise went away but I still have a noise that happens when accelerating. Almost sounds like a rod knock. Im really stumped as it just broke 100,

My 2015 odyssey with 95k making the same sound. The timing belt tensioner was toast . It’s in the shop now for a timing belt replacement.

My question to you is how much should this procedure cost?🤔 please respond. Thank you Tim!

Just curious why changing the water pump is often recommended at the same time, when the tensioner is the problem. Is it just a matter of doing it 'since you're in there anyway'?? Thanks.

Dayco had an issue with the manufacturer of the tensioner a few years ago. Had the same issue. Replaced with OEM tensioner. Won’t buy Dayco tensioners anymore.

My Odyssey is making the exact same sound but the mechanic says it is caused by the cam shaft.

Where are you at in Anchorage, what shop

How much does a job like this cost parts & labor ?

My check engine is flashing and it does that same noise

👍👍

I've seen aftermarket hydraulic tensioner fail at 40k , I will only use Honda parts , those engines bend valves when timing belts fail

My honda pilot 2014 makes knocking sound under acceleration only.

My house is a huge mess. Wish I had an earthquake to blame it on! But seriously -- glad all is well up there.

Please use honda parts or at least Asin kit from Amazon. I had a Gates kit and tension was replaced only after 50,000km. That is my experience from Gates

Lol…I got screwed by Honda and govt who didn’t force a recall for the oil use/piston ring issue. After I paid for the damn piston ring replacement the valve sounds were way louder. Not valves they said. Said it was camshaft and then the time belt tensioner. It sounded NOTHING like you showed. A shop I trust got together with his friend at another dealer and they all agreed the valves were loose. He got in there and they were ALL loose. Quieted down to normal after that. The dealer is either incompetent or they are crooks. It was pathetic.

What's something like this cost to fix?

Alaska? Sorry but I think I will take my pilot to a mechanic here in the Midwest.

That did sound like some evil tappit/valve/lifter related problem. I bet it's as quiet as a bee farting now lol :-D If bees fart, that's another story :)
