OK I have a 88 Grand Wagoneer with the all too common low oil oressure problem. At start up its OK but once it gets warm it goes way down. When its warm and at idle its at zero. What I would like to know is, whats the easiest way to fix this?? There is no ticking or knocking coming from the engine and I would like to keep it that way! What I had figured on doing was pull the TC cover and rebuilding the pump and changing the chain and water pump while I have it apart. Does this sound right? Is the Edelbrock timing chain any good?? Any other advice? Thanks!
