DUbob, Thanks for the advice. I will look down thru the throttle body and see if there is oil. I have the air intake cover off. If I pull the plenum I think it would be smart to do a valve job as well? Ive read if you go that far you should replace the lifters. They say that the magnums use a roller system. Do they all 5.2 magnums have rollers or is it after a certain year?
73AbodEE, When you say new gasket were you meaning just a TB gasket or plenum gasket? Did you do a compression test or leak down test? Also when you say reset the computer what did you mean and how did you do it.
Thanks Rod
