Oil Filter Concerns

[Calrenman]

Before the valve burned my compression was high normal before the oil test to check the rings with little Slight raise after the ring test.

The motor in the Geo had 100 k on it. My V8s ised to smooth at certain place in the cylinder I think it was top and bottom center and outsid but I ran the piss out of those moters (350 chevy).
Toyota is not what they were in the 90 or early 2000s. Sorry you were burned.

fwiw cross hatching life comes down to 3 things run time/milage, heat consistancy and overall ring seal/wear

in other words..sloppy rings will never get rid of the hatching, low run time wont wear it either and an engine that never gets too hot or too cold will also never wear it out..ive taken apart 100k mile 70s v8s that still had faint hatching ive taken apart ones with 30k that were slick as a mirror...the oil used has NOTHING to do with cyl wear...oil only has a genuine effect on bearing surfaces..the cyl's are scraped clean every stroke..besides unless youve got an engine wiht oil sprayers little oil gets in there anyway
