Is a manifold leak dangerous in any way? How critical is this repair? I know nothing about cars, but I’ve been told by my garage that I have a manifold leak.
Will this exhaust leak also cause a P0032 and P0052 check engine light code? I already replaced all my O2 sensors and smell a strong exhaust and have that ticking noise.
+C Otake We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
@@holtman2598 : That's more likely to be a loose "V", or "serpentine" belt than a leaking manifold. Rub a bit of bar soap, or perhaps a bit of Dawn onto each belt, if it stops squealing you've found the "offender". The next step is to re-tension the belt. If the belt won't re-tension, or resumes the squealing it may be time to replace the belt. If you end up replacing the belt, make certain to get the proper amount of tension applied to it. Remember, the application of soap to the belt/s is ONLY a "diagnostic tool", NOT a repair!
This is very helpful in explaining the ticking noise I hear when my engine is cold. Mine goes away usually within 30 seconds or less, so probably a smaller leak than average but still a problem to look at.
What if you have ticking that doesn’t stop as it gets hot but it does slightly reduce? Also when car is up off the ground and your under it you can feel a whoosh of exhaust when have a buddy slightly torque the engine putting it in drive and break torquing it and facing where the pipe comes down to the cat. Can also smell exhaust in the engine bay back where the manifold is hidden behind the engine but no whooshing of exhaust blowing upwards like is under. The issue is we don’t think it’s manifold, sounds like leaking manifold but the whooshing underneath makes us think it’s elsewhere, that large of a leak in the manifold would likely poisoned me on a road trip by now makes us think that the leak is further down stream but just above the cat. But we can’t locate it and it’s a huge job to replace it because looks like have to drop the subframe and no one wants to do that.
dont normally subscribe to pages like auto cars but you guys deserve it! The video was clear, concise, and repetitive with important tips and information! Great vid guys!
My aunt once had a car that would blow anti-freeze in through the a/c vents. I was a kid and didn't understand the reasoning behind it. But I can remember looking at the vent and wondering why the air coming out of it was... visible to some degree
I have a 2018 Nissan Altima, and it started with a loud consistent ticking sound, and was noticing it suspiciously went away after it warmed up. Also, it was unbelievably "exhausty" in the cabin and under the hood. This absolutely solidified my suspicions. Thank you!!
How the hell did the person recording not tell you to say vehicle properly?? Or ask why the hell you are pronouncing vehicle like that and adding a R sound to it???
I got my response after many months trying to understand why I have an exhaust buzzing noise between 1500 RPm and 2000 RPM when engine is warming up. Noise almost disappears when the exhaust system reaches a very hot temperature (Heavy traffic driving for 20 minutes). Then the noise comes back slowly when cruising at high continuous speeds (When exhaust system cools down due to the cooling system and high airflow underneath the car)
Confirms what my mechanic told me. My truck is in the shop right now getting a new manifold on the right side. That's where I started hearing the ticking sound. In fact I hear this sound in a lot of vehicles. Yeah, my next door neighbor who hasn't gotten hers checked out yet. Thanks for a great commentary on this. I subscribed to your channel and gave you a thumbs up.
When I turn my car off and it’s parked I hear a very rapid ticking noise like someone it tapping a small wrench really fast near the back or mid section of my exhaust and this noise actually goes away once the system is cooled off. But I hear no ticking when the car is on…I have taken it to 4 mechanics and they have told me there isn’t a problem. I’m not convinced.
Hi there, would the typical 'ticking' sound you mentioned of a leak very close to the engine be the short ticking noise I can hear right at the very beginning of the video when the engine starts? I have exactly that sound, I hear it mainly while driving whenever the motor has to pull, when I accellerate. This sound is getting louder and started over a year ago, however doesn't go away when the motor is heated up. Thanks in advance for your help!
I'm having the same issue and it's ever since I put a new set of aftermarket headers on. It seems to get worse when it's warm and will only make the sound under load. I can't for the life of me figure out what it is, it's definitely not the valve lifters as the sound isn't coming from them.
So you're saying that if my manifold is connected to my catalytic converter I can get a lien condition as well as a p0420 or p04302 my manifold is leaking correct or not there's nothing wrong with the O2 sensors are replaced it twice already
My car got the same code. It smells like gas when I turn on the AC or the heater. I’m assuming it’s coming from under the hood. I used cataclean n cleared the code so it hasn’t popped up and it’s been longer than a month.
Anybody know what could possibly be causing my vehicle to tick after a cat delete it’s a very loud ticking noise that will eventually die off once my vehicle has shifted through gears
Very informative. I just got a 2006 Honda Element that had a bad donut gasket and I just fixed that (what a relief for the ears!), but I found it ticks under load, whether the engine is hot or cold (the ticking under load doesn't go away when the engine is warm). Could this mean the manifold itself is fine but the gasket is bad? There are no leaks coming from the new donut. Thanks in advance for your comments.
Looks like I have a an exhaust manifold leak. I can see it bubbling. I am also loosing coolant and have white smoke. Does that make sense? Do I also have an intake manifold leak??? Vehicle is a 1989 F240 with a 460 7.5.
Soap and water. Use a shop vac on the blow side in your exhaust to find a leak on joints and seams instead of going by noise. Itll also keep it all cold so you can touch and work on the exhaust
Okay so I have a 2017 ram 1500 penstar engine and I have a ticking noise in think it was engine related but watching this makes me second guess. So in the morning is when it’s the worse as it would be if engine related and it gets quieter but doesn’t go away completely and it does increase under acceleration. So my question to you is it even worth what you think it could be
Does anybody know if a manifold pre cat like shown is supposed to build up heat while at idle? Mine measured 330 into manifold 550 at the front of the cat and 330-350 at the back. Does this mean this pre cat is bad or that it is functioning? Once again these were measurements at idle
Jeez I just had some shorty headers installed on my 2013 F150 I also hear a slight ticking noise in the morning; must be a very small leak cause it goes away in the day
im working on a 2003 gmc savana van, i hear a ticking when started up cold but i still hearing the ticking even when its warm, but when i drive it and give it some gas it goes away but comes back when im idling what does that mean? also symptom on possible maifold leak?
Hello everyone, question: do you need to replace that if you have the leak. If the sound doesn't bother you or there will be some other complication if not replaced. And if you do need to replace that for some reason, what is the longes you can drive without replacing it if the sound just appeared?
Buy aftermarket bolts, the ones used are grade 8 I believe but go with a grade 9 or 10. Just take an intact bolt into a bolt shop and get them to match up width, length and thread 😘
Can anyone help me with this, pleas? My engine has the ticking when I start it. It is gone after the engine warms up idling but the ticking resumes as soon as I hit the accelerator. I can be going down the road at 5 MPH and if my foot is on the accelerator I hear the ticking but if I remove my foot from the accelerator at that point the ticking goes away. It comes right back if I hit the gas pedal again.
My 2007 Chevy 4.8 makes a ticking/tapping sound only after the engine is at operating temperature. The noise sounds exactly like lifter tapping but goes away after a few minutes. Back in the day of muscle cars that was indicative of an exhaust manifold leak. My guess is that when the thermostat opens up and the water starts to flow through the aluminum heads, they react to the quick temp change. But the manifolds being cast iron are not getting any cool down effect. So maybe this is why the tapping sound only happens at that time (operating temp) and not at start up or constant while the engine is running the whole time. Just guessing. Gong to try the shop-vac thing and see. But not sure it will help seeing it only taps after it's warm and for a few minutes, then it goes away and purrs like a kitten for the rest of the time.

or you could use a shop vacuum with it blowing not sucking and with everything cold put the shop vac in the exhaust tip and tape to so it doesnt fall out and then turn it on and take soapy water and spray down the exhaust that is the easiest way to check for an exhaust leak been doing this for years as a auto tech BUTTTT make sure the motor and exhaust are not hot and it hasn't been ran for a couple hours
@1auto Lenny Would it cause smokey from manifold gasket too? or would that be the valve cover gasket only? I changed my water pump in my 3.9v6 Dakota at start up to burp system passenger side, started to smoke really bad. Was told its valve cover gasket but Im pretty set its mainifold gasket.
The best way to check for an exhaust leak, is to use a shop vac. Insert the shop vac end into the open end of the exhaust pipe and if you have dual pipes with a crossover pipe you'll need to block the other pipe by inserting an old t-shirt or shop rag. You'll want the shop vac blowing air into the exhaust pipe. Now, you don't have to worry about the exhaust leak sealing off due to heat, just grab yourself a spray bottle of water and dish soap. Go along spraying the soapy water and as soon as you see bubbles you'll have found your leak.. but don't stop there, there could be more.
Simple way to check leaks is to use soapy water and test to see where bubbles comes. Apply soapy water on possible leaks area first. If you have leak in exhaust prior to catalyst, you will see 420 and 430 code and engine light on. I don’t why some will open all parts first and use eye ball to inspect the leak.
I have a leak coming from where the donut gasket is. Could this be a leaking coming from somewhere else and just happen to find it’s way where this part is!
@1A Auto: Repair Tips & Secrets Only Mechanics Know I have a 1.8 zz Corolla. I've had this ticking since over a year now. it comes with more load (more passengers or AC/headlights on) I'm suspecting a warped exhaust manifold with leakages around the gasket. Do you think this leakage can screw with the performance of the car? because when the noise disappears sometimes, the cars performance is ALOT better?!!
Hi I tore my manifolds off. I have multiple broken manifold bolts as well as shot gaskets. My truck makes a ticking noise that is louder when cold but doesn't go away when truck is warm either. Could this be my problem? 2014 dodge ram 1500
I don’t get a ticking noise. It sounds more like chirping or squeaking, or even metal to metal when I accelerate. It is less audible when the engine warms up. Does this still sound like an exhaust manifold issue? Gasket? Loose bolt(s)?
I have a Nissan 2018 Frontier King Cab 4cyc with an exhaust leak at the exhaust intake manifold not at the head but a little waist down where it's covered by heat Shield bolted in another one a little further down which is clamped together where to exhaust pipes meet and is covered by heat shield it has a aluminum o-ring as a gasket how do I get them off to replace the aluminum o-ring on it
Awesome video, I was about to just tighten up my bolts there but after seeing how bad the surfaces can get and that cracks can show up, I'll take out the manifold and give it a better inspection. Also hadn't even thought to use my hand to feel for gasses when the car is just turned on
you did not talk about the smell part. just saying lol I dont have an issue, I was just here to see what it was because I dont know much about cars. great video thanks.
