89 Chrysler NY 3.0L Mitsubishi...........car in otherwise great shape..smoking though. I've been told it's valve stem seals...will replace in a month or two..in the meantime, smoking is horrible....I've been told that Restore doesn't work at all to cut down on smoking. How about synthetic oil? With combustion point so high in the engine, would synthetic oil burn and smoke less? Would it make a difference?Theoretical; bad valve stem seals...smoking...synthetic oil?
You have a condition called out of specification valve guides. No valve seal in the world will remedy this problem. What most likely has happened is the clearance between the valve stems and the honed guide holes has expanded over .003 from that point on oil starts sucking down the guide in decelleration causing oil smoking. If you or a friend sees smoke all the time while your car's on the road you probably have stuck or warn piston rings. A compression test will differentiate the two problems.Theoretical; bad valve stem seals...smoking...synthetic oil?
not very much
