The oil pumps on the non di models had check valves in the oil pump which
should have held the oil back from entering the cylinders. It sounds like the
check valve failed in your oil pump. you can either buy a new oil pump or you
can install the check valves that the first year 2000 STX DI used as a fix
after they realized that the DI oil pumps didnt have check valves. The price is
probably about the same. It really only becomes a problem when you let them sit
for a while.
