rinngs on the piston, or the piston itself, Tale a panel light and look into
the cylinder to see the top of the piston. Turn the engine so that the piston
is at the bottom, and you will also be able to see the cylinder walls. If they
are scratched up really bad, then the rings have broken or turned sideways, if
there is a hole or a crack in the piston, then look for a used engine. The
lifters may be or may not be stuck open, but the element that is the key, is the
oil on the plug. I am an advanced level, master technician with 23 years fixing
cars. If you donot have a light that will fit into the spark plug hole, I know
where to get one.

and it progressed from a minor miss on #3, reported by OBD2 - to a

It had gone to a "Canadian Tire" store for a tuneup when the CEL came
on, and within less than 50 miles it was scrap.
