In Reply To 2nd, did you ever find your vacuum leak? posted by HighPsi on December 20, 2009 at 08:20 PM
     
Message is coming from below the right-side of the 2nd-from-front intake runner. I just pulled the plenum and replaced the gasket for this very leak. The gasket I replaced showed no signs of being blown through (it was only 6 months old itself).
I'm thinking it must be from the lower plenum? I cant imagine where else it could be coming from. It never even occured to me that there could be a leak below the lower plenum because it has not been touched since being torqued down at the factory...............EXCEPT when I had the upper plenum off and decided to pull the motor....I bolted the engine sling into the lower plenum to pull the motor....forgot all about that.


dammit

Going to have to wait until the spring. I'm moving in 2 weeks and just need the car to run well enough to drive to Dallas in order to ship it ahead of me.

"The American people will never knowingly adopt socialism. But, under the name of "liberalism", they will adopt every principle of our socialist program, until one day America will be a socialist nation, without ever knowing how it happened.... I no longer need to run on the Socialist Party ticket because the Democrat Party has now adopted our platform."

"Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."
