Kris ~~~ To determine your problem bring the bad cylinder up to top dead
center  remove plug and run a air test. You will need a air compressor  &  a hose
that has a fitting for the spark plug hole & on the other end a fitting for a
quick release from your air compressor hose .  Set the air regulator at 50 to
75  lb,s If the rings are bad you will hear the air coming from the  oil fill
area .~ if the exhaust valve is burnt it will come out the exhaust pipe.~~ if
the intake valve is burnt it will come out the air intake . you also may have
a notch burned out the side of the head or piston & cylinder area.If you dont
have the equipment to do the test find a good shop that can .We can help you
with the parts you may need . Good Luck Don at DVW Import Auto Parts  1-800-248
