i think my piston rings may be going bad....slight blue smoke when first starting, then it clears up and then runs smooth... any ideas of ball park price ranges for repair by certified repair shops? I hope this isn't the case though. This issue didn't start until I installed an oil filter relocation kit and accidentally over filed the oil a bit. I have since drained it and started from scratch with the install and oil fill, I am hoping it may just be blowing out some oil that was unable to drain!
That is a typical sign of valve seals leaking. When the engine off, a little oil seeps down the valve stem and then causes smokes when the engine is started. Since the seepage is small it takes a while (like overnight) for enough oil to accumulate to cause smoke. Running there is usually no sign of smoke (unless the seals are really gone).
Worn piston rings will cause smoke while running. Get on the throttle hard then coast (high engine vacuum), then get on the throttle again, if you see smoke now then maybe the rings are worn. Also worn rings will allow combustion gases into the crankcase. Remove the crankcase breathe or pull the oil fill cap and see if any smoke comes out. If no, then your rings are probably good.
