Hey folks, this rig is running very rough. Has some sounds like a leaky head gasket but no coolant on ground or on engine. Alot of oil at rear of pass head. Cracked each fuel line while running- it did smooth out some but not alot on number 4 cyl. Removed pass side injectors- noticed #4 wet, and fuel sitting in precup. Owner thought it was a broken valve spring, but all appear to be intact and nylon keepers are also intact. The inside of the intake is BLACK with oil. It looks like somebody painted it!
My worry is #4 injector crapped itself, he continued to drive a few hundred miles this way blue smoke and all, and I wonder if the piston/cylinder wall is melted (hence the oil in the intake) or if the head gasket is blown. Valve train seems to be ruled out, though checking the lifters seems difficult without further disassembly.
Thoughts?
Temp guage was normal driving to my house last night- 5 miles and 85 degrees out. Does not smooth out much while driving.
