Symptoms of a Bad Intake Manifold Gasket Leaking and when Replacement is Necessary

Can I use permatex gasket maker instead of the hard gasket for the exhaust manifold?

I hear hissing when turn my car off it's fmgot a p0302 code and the hissing sounds like it's on the side were cylinder two is on it's a 05 marquis qith the 4.6 infamous for leaking intake manifolds

I've had a vacuum leak for a little while and tried propane on the vac lines with no results, pushed everything right together and nothing. Then one of the guys at work said it's probably the intake gasket. Well, it seems to be the issue, your symptoms match exactly. Keep up these videos. Not enough people know how to fix their vehicles anymore. This is just an issue I haven't had before

How much does this cost to repair

2002 Honda Accord 2.3 Motor my RPM’s go from 1000- 2000 up and down, changed AIC valve, and it still does the same.What could it be 🤔

Thank you for this video!

Comments made me subscribe

Will this cause p0401 Egr code

SUPER VIDEO!!! To the point!!!! Helpful even for those of us who aren’t super mechanics!!

I got a 2.0 tdi, it makes hissing sounds when I accelerate, starts harder, and it goes into limp mode when I get over a certain rpm, usually 3500 in 5th gear usually, it does not have problems for example in 4th gear ar 4k rpm, could it still be the intake manifold gasket?

Vacume leak would be picked up by o2 sensor and ecm compensate by adding fuel fuel trim would be rich but very unlikly causing rough idle

Thanks sir, we need this type logical explanation .
Not a long lecture, thank you.

What if there is smoke coming out of the exhaust manifold?

hello in my civic 1997 when acceleration to 3500 rpm then release i hear a huge whistling noise , this could be the manifold gasket ?

Cars with map sensors equate for the intake manifold pressure leak and yah know gives you time to deal with it later.. Dont matter. But maf sensor is before air enters the manifold. With the maf sensor intake leaks are bad.

so i just recently cleaned my throttle body on my 05 gmc sierra 5.3 just because i had no check engine light on for it or anything so after i cleaned it i installed everything back the right way and did the 3 minute idle learn well tried now when i turn it on it warms up good but once it warms up it starts to surge the rpm goes up and down then when i put it in reverse or drive it revs up and going into gear or to reverse whatever im doing when i drive it and step on it it feels good i feel good power but as soon as i let go the gas now it says reved up or accelerated then once i come to a stop it kind of goes down and just starts surging again do you think this could be it or what else do you think it can be i replaced air filter cleaned my maf sensor do you think this may be the cause of that ?

I heard a suction sound coming from the bottom or my suv where thats located it might be tat issue but I get no codes and my car smells like pure gasoline and fumes at random times. Car also has hiccups rpm drops and comes back to its steady rpm makes tye car tug or jitter.

Bought a 2005 tahoe from a pretty shady guy almost 2 years ago. Went to drive it home and it cut off and wouldn't stay running. Flash forward a year and i chased down everything related to random misfire that you can think of. Even put high flow cats on it. Found this video and it made perfect sense. The manifold gasket is the only thing i didn't think of. Changed it today. Haven't run it but im confident the gasket was the problem the whole time

Hey buddy. I have a 2003 Odyssey that makes a weord FOOOMP sound like launching a T-shirt out of an air gun. Not rhythmic. Irregular and abiut 5 a minute. Any ideas?

He's definitely on point. I recently bought a 2006 Volvo XC90 4.4L V8 and supposedly they changed the MAF sensor. So I'm guessing it's new. I'm getting a lot of carbon build up and poor power and gas mileage. I'm going to change the MAF sensor and use Sunoco gas. Hopefully this will help a little bit. Next, would be to change the intake gasket to cure the air ratio.

Hi great video really good tips. Quick question what if the vehicle is a diesel engine? And it could be possible to get code P00BD?
thanks in advance

I think my problem was a valve cover gasket. Oil is everywhere, and smoke was coming off the manifold with an oil burning smell. I replaced my gasket.

Great video, helped me out massively!

Straight up and to the point. No life stories or history of the things that nobody cares about. Just facts that pertain to the point of the video and no wonky footage. Love it! Keep up the great work!

I have a poobd code. Can that be intake manifold related?

Was getting code P1273

Would the hissing noise sound like a whistling noise?

Is it a hissing noise or does it sound like an air compressor when you pull the trigger on an air nozzle? And mine only makes this sound when my rpms are high. As soon as it shifts and lowered rpm the sound stops.

I’m getting white smoke sometimes and rough idle. I changed the mas air flow sensor and also the valve cover on the driver side. But still getting smoke at times and oil consumption so what could it be

Would long starts be an issue?

Hello, can you tell me what the tightening torque will be for the intake manifold bolts in a Mitsubishi ASX 1.6l petrol, engine-4A92, using a torque wrench?

This makes total sense! P0171 code is popping up and I have hissing sounds, and RPM runs ups.

What is the synthopms to the car when you have a vacuum leak caused by the manifold gasket?

I bought my uncle a 96 Jeep cherokee with a 318 and its got alot of water in the oil in it. My uncle thinks its the plenum gasket leaking. Could this be it?

Literally just liked and subscribed because you know your stuff. I was getting P0300 and P0405 but the egr is deleted when it was rebuilt. Coils are good spark plug wires are good and new spark plugs installed. Today when I was inspecting with it on I gave it a rev and I could hear air being sucked in somewhere from the front of my intake manifold. The reason why I think you are right is because I’ll have really rough idle when completely stopped and she will miss fire and you can feel it

2015 jeep patriot no start but cranks over n shoots out antifreeze from exhaust….any ideas why ?

Can a bad gasket cause coolant leak into ignition coil?

Propane is a new one for me

bro u a star really appreciate for your knowledge and patient

Question: if it passes the starting fluid test, does that necessarily mean it's good or can there still be a problem with the gasket?
Thanks!

My car has no problem at higher speed but also at idle, its maybe little rough but no code, no stalling, nothing. But on MOT, there is high O2 % and lambda at idle az 1,8. Exhaust checked and no holes. So it could be intake gasket ?

Can that cause the airflow sensor not to read?? Cause i bought a new original sensor and my car doesnt read it what i hear is a whistling sound when i drive

Will a leak cause the idle to be irregular?

I have a 93 Chevy and I don’t hear a hissing sound but it idles and runs rough and would accelerate on its own at times and now it just doesn’t turn on at all, I cleaned the throttle body and replaced full pump and many other parts, can this possibly be it?

We have a 1989 Honda Civic 1.5 There is hesitation in the throttle at lower engine speeds. Seems worse when the engine is not fully warmed-up. We have none of the symptoms mentioned, but perhaps still an intake leak. Any thoughts?

Is there a way to seal it up without removing and replacing

is it possible for water to get into the engine causing milky oil as well? no white smoke from exhaust but performance its bad and milky oil dont think its head gasket perhaps a combo of bubbles in cooling system and leaky intake manifold?

Hi I have a 2015 Silverado and is reduced engine power
I change the throttle body and master flow sensor
And it was running good than on my way to work it’s started whistling sound
And it went back on reduced engine power mode the whistle seems like it is coming out of manifold but iam not sure if it will cause the engine to go in reduced power mode and now it won’t even turn on can you give me a guide on what you think it is?

I have p0171 p0174 on my 01 towncar. Hards starts slow acceleration, slow going up hills.
