I have a 98 Park Avenue with 55K miles on it. Because of the infamous intake manifold leak associated with these engines I keep a close eye on it for coolant leaks. Today while I was inspecting my engine compartment I noticed a small metal cover about four inches long and about two inches high with two 8mm bolts through it on the rear end of the intake manifold directly below the area where the metal EGR hose enters the intake manifold. There seems to be some seepage around it and the substance appears to be oil. Can anyone tell me what this thing is and whether it part of the intake manifold leakage problem. Thanks.
