The engine in my AA hasn’t been running for a while and I have no history. Has great compression on all four but pan and valve chamber really gunky. Bottom side looks decent, no stuck valves etc.. I can see shims on rod caps. I am going to pull engine and go through it. This is my first experience with an A engine. I plan to start by checking and adjusting bearings if possible. If cylinders look good how do you check for wear- cylinder to piston clearance? Any suggestions? I will definitely pull crank and clean all oil passages etc.,. Should I go ahead and replace rings while it’s out if everything else looks good? Valve guides?
