my thoughts are of course intake plenum problem, but its not showing up inthe oil. maybe lower intake gasket failure? if so how can i tell with out tearing down? ever heard of plenum leaking into throttle body? maybe bad throttle body? -continued- |
I love a challenge and working on cars, but right now i dont have the money to start trying things like a stab in the dark. this coolant loss is big and has potential to destroy this car so gotta find it. was thinking about tearing down and inspect plenum and replace lower intake gaskets. then if found plenum to be bad then go get the kit. btw i have had a lifter recently start to click or clang mor like it, in the morning. maybe related to coolant loss( washing that lifter out)?? this has got me worried and baffled, car has 130,000 and is in perfect shape other than this, HELP i will check this post regularly and will include any more info you guys or gals might need to help me diagnos this thing. btw love the car, but its soon on my black list,lol. thanks for reading or helping Joe
