Started today on my overhaul. New oil pump, New Heads, Master Brake Cyl rebuild and a new rear wiper arm for good measure. Upon tearing things down it was obvious I had trouble right from the get go...(pic 1) Oil coming from my air intake was not what I wanted to see. After that, when I took the valve cover off (pic 2), I was even more shocked! The oil build up is crazy. I always change my oil and filter on avg every 4k miles and use Rotella 15-40 with a Mobil 1 filter. I guess I'm looking for confirmation that the build up in the valves is from a bad oil pump. My oil pressure lately has been pretty sporadic but never less than 15 at a stop. My CEL came on a few days ago and read misfire in Cyl 1, and today on my way home from last drive, it was blinking when I pulled in the driveway (Horrible spot for CEL, I can barely see it behind my steering wheel).
Any how, I have everything torn down but cannot get the heads off. I cannot break the bolts loose and fear I may have rounded one bolt. ( I stopped immediately after I slipped off that one and put tools away, it was late and I was tired.) I was trying to look in the Rave manual but cannot verify that the bolt is a 16mm. It seems a tad too loose but 15mm is too small. Is this by chance an SAE left over from the Buick motor?
I knew I needed a new Head Gasket, but wow. I could be in real trouble here....
