Why not just do a compression check and leak down BEFORE you decide to rebuild a 90,000 mile motor. COuld be that during the extended storage oil leaked out of the tank and eventually found its way to the exhaust which would explain the smoking. If the engine isn't making any funky noises and the oil pressure is good, I'd drive it a bit to clean it out and then do a comp./leak down test. Cheaper than a set of P&C,s
