so we changed my spark plugs and put in a new ERG valve. had to remove the alternator to gain eayser access to one of the plugs. (3.1 engine). got everything done and while in the car, it kinda sounded like the defrosted was on.
it was making an unfamiler noise. the EGR valve came with 2 gaskets- one which i have no idea where it goes.. so i didnt use it.

any idea what this new noise could be?

 

Did you put a gasket where the stem of the egr meets the exhaust manifold? Mine's got a pretty good leak right there due to broken bolt and no gasket...

 

thats the place you only take out 2 bolts correct? yeah i put a new gasket there. then theres anther gasket though thats kind of similar but i used the one that looked more like the orgional one. *shrugs*


oh.. can you hear your leak?

 

I can yea.

 

is it a gasket that goes to the bendable pipe? the one from the egr stem to the upper plenum neck?
