Eventually bad guides will show up during leak down test as valve starts to walk over at the seal. Last 3.6 I did had a full half circle where there was no contact at all and valve had a crack about 1/16 inch long. Cylinder number three, it had about 60% leakage. It’s never a bad idea to do leak down and compression tests when wondering about engine condition.

I do not disbelieve in anything. I start from the premise that everything is true until proved false. Everything is possible.
