Re: 98 buick lesabre 3800 (k) engine
I just rebuilt the engine on a limited basis. New crankshaft, bearings, piston rings and all seals and gaskets. The engine had 150,000 on it. Reason for teardown was bad piston bearing which damaged piston rod. Its been replaced. I was having problem with oil pressure before also. Had heads magnafluxed and no cracks.
