97 Integra, around 265k miles. Head gasket rebuild about 5 years 20k miles ago. It was running fine since the rebuild but was losing coolant about 2 years ago, I brought it in to a local shop recommended by people here, and the mechanic found a bypass hose leaking a lot of coolant and he replaced it. The car is burning / leaking oil. About 3 weeks ago I noticed engine misfires and CEL turns on during commute. I parked it when I got home and started driving another car instead.
Today I pulled the spark plug wires and tried to pull the plugs out to see what it looks like. It was stuck real bad, to a point that my AllTrade (Kragen house brand) spark plug T wrench is bent when I try to remove it. When I pull the wrench out the tip is full of oil. I've never seen this in my life. This happens on 3 of the 4 cylinders closer to the timing belt.
I suspect the spark plug tubs seals are bad, but why would it push so much oils out? Would it be PCV going bad? Would it be bad rings -> too much blow by?
How do I clean the oil off and what should I use to dislodge the plugs? Brake cleaner? Which spark plug wrench do you recommend?
