exhaust leak

[ooraceredgt]

cant figure out where exhaust leak is coming from. checked all joints on exhaust and even had smoke test done. is it possible for the manifold gasket needs to be checked/replaced. i dont know how long a stock gasket will last.

Why do you think you have a leak?

Check your EGR pipe. Check for tight connections and also check along the pipe to see if its cracked. They can crack very easily. My brother had an exhaust leak and it turned out to be a cracked EGR pipe.

Did you run seafoam through it? That smoke is very white and you could spot the leak easily....

i can here it "spitting"

check the pro-chamber to manifolf flange. if its leakign form there replace the factory studs with normal ones (with no shoulder) or bolts. mine leaked right there, and the flange bottomed out on the shoulder - so i had to put some bolts in (didnt have studs on hand)

spray soapy water on the joints, and look for bubbles

did you use different studs when you installed the pro-chamber?


also did you use the stock copper gasket on the pass. side or the paper piece mac sends you?

I would check your plugs, I thought I had a exhaust leak for a while and it ended up being a loose plug that eventually got spit out, check your plugs!!!!!!

i used a new gasket from ford and the studs were replaced when i installed the prochamber. i'll get some seafoam tomorrow and double check for any smoke. also i'll check the plugs. thanks

replacement stock studs or the napa stud kit?

That works for about all of about 45-seconds until the exhaust temperatures burn off the soapy water......so you'd better get your ass underneath the car quick.

Damn I hope you caught it before it did any damage....

Can someone describe what the sound is like if a plug is loose. I suspect I have a leak, but it doesn't sound the same as the last exhaust leak I had.

 

[Gearbanger 101]

It'll sound like a progressivly loud "ticking" noise, similar to a leaky header gasket.
