This brings back BAD memories... The ONLY engine I ever attempted to rebuild myself was in a 1960 Sunbeam Alpine. Folks bought the car after the engine blew in the the '63 Falcon I had learned to drive on. Then, they found out the Sunbeam's engine had bad rings - lots of blow-by. When I got it all buttoned up, I had a few parts left over. Turned out they belonged to the oil pick up. Ever since, been real hesitant to get involved in anything major......
