Re: 97 Achieva mystery
Heres the answer to the mystery. This engine (like so many 3.1s) had an intake leak (antifreeze). This results in coolant leaking onto a cam bearing which finally seized the cam and the camshaft broke. This stopped the oil pump (runs off of cam) left valves in the cylinders which hit pistons. Final call, engine junk. Replaced engine and waiting to fire.
