Re: Stuck Oil Pressure Relief Valve: what do I do? Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Stuck Oil Pressure Relief Valve: what do I do?, iveand ![]() |
Well, the main reason why the piston is stuck is most likely because the teeth on balance chain sprockets are grinded down to nubs, and that debris has been passed through between piston and bore in engine cover leaving scratch marks.
My suspicion at this point is that you need new timing chain and guides, oil pump gear and cover, front engine cover, oil pressure piston. Drop the oil pan and remove cylinder head to replace timing chain and remove balance chain system.
Another place to look for wear is to remove crank pulley and oil pump cover. The problem is that the HUGE snap ring that holds the oil pump cover can be a challenge if you don't have a HUGE snap ring plier.
If you find a lot of scratches on the oil pump cover and gear it is also a tell tale sign of balance chain issues.
