So here's one for you all: I have a high mileage track car. I use it 60/40 street/track. Everything great in street driving until cylinders start misfiring. I limp the vehicle back to storage JUST as the engine light comes onand engine stalls. We pull the intake and emissions lines. Very dirty. Throttle body pretty oily (new oil) and there's plenty of new oil puddled into the intake plenum. I will replace ICV and all associated tubing. I will rebuild fuel injectors as some tips broke upon removal. I will clean intake manifold and recondition fuel lines, etc. 2 plugs were completely munched at the tip; one coil had disintegrated. Oil is leaking through, I believe, the valve cover gasket and into cylinders. This is because loose spark plugs started literally vibrating in their threads. When I removed the plugs there is definitely oil in the cylinders above the pistons. I am scared... My questions: - is there any reason I should pull the head? ..worried about plug diode pieces in cylinder - at the very least, should the valve cover gasket be replaced before firing the engine up with new plugs/coils? - if, in fact, I may have hydrolocked the engine what is the procedure to rectify the engine? THANKS.
