I have an 04 with 60k, My car wont pass deq because she is running lean! A mechanic did a leakdown/smoke test and found a vacuum leak right under the pully were the intercooler fluid goes in. The Leak is fairly good size, he said i need a new gasket in between the plenum and SC! I just need help on knowing what gasket that is. Hopefully i can just replace the intake man, and plenum gasket's and be all set anyone have a good part # that would help. Thanks
