Question about 2002 Pontiac Montana

2 Answers

Possible cracked manifold

I have a noise coming out of the exhaust towards the front of the car.
The mecahinic says it is either a cracked exhaust manifold or a bad gasket. Either way, he claims it would take hours of labor just to get to the manifold to see what the problem is. The repair would cost around $600.
Does this sound correct? My mecahinic, who has been a mechanic for years, says he never had to get to an exhaust manifold on a Montana before.
Is there a cheaper way to do it?

Take it to a muffler shop, they work on exhaust problems all the time and may just need a new gasket from the collector flange which would not be that expansive. Almost all of them will inspect for free since there looking for your business.
I have not sean exhaust manifold go bad before the whole car or truck and the exhaust pipe is stainless so good chances are that it's the flange gasket or the bolts may have broke due to time and vibration.
Good luck and keep me posted.

If this is made of many steel parts and welded together its probably cracked. If cast metal the seal is bad. $600 is a fair amount if a new manifold is used for repairs

Exhaust leak for a 2001 exhaust leak


Check your exhaust manifolds. I had one and the exhaust manifold on the back side against the firewall cracked. Of course it was the one that is hard to get to and not the easy one. You will probably need to remove some heat shields to get a look at it. On mine it was easier to look at from underneath the car. But be sure to check your muffler and exhaust pipe as well for damage or possibly rusted out. Start the car and track down where the noise is coming from. If you end up finding that one of your exhaust manifolds is cracked I recommend buying an OEM one and not an aftermarket one. They will tell you that the aftermarket one might have a lifetime warranty but that does not include labor. I bought an aftermarket one and a few months later it broke and I ended up buying and OEM one and put it on and had no more problems.

Exhaust makes a loud tick when first started


usually an exhaust leak, at exhaust manifold to head, broken stud maybe. Use a piece of hose to your ear and listen at manifold.

96 Ranger, "Popping" coming from engine compartment


Possibly you have a leaky or cracked exhaust manifold. After the engine heats the metal expands and creates a larger gap. As the engine speeds up the engine noise overcomes the exhaust leak noise and you don't really notice it much until the vehicle gets in to a hard pull or comes to and idle.

My 2000 Honda Accord is very loud upon acceleration. It's not the exhaust or the muffler. I know it has something to do with the manifold. Can you tell me in more detail what it could be? Thank you
