that doesn't mean you have bad rings, you need to do a wet compression check, that means put a teaspoon of oil in the bad cylinder, and do the test again, if it doesn't change,the issue is in the head, you could have a burned valve or a crack in the head etc, the two middle ones both being low also could indicate this, possibly a crack between cylinders in the head.Quote:

I honestly didn't examin the valves when we changed the gasket. maybe a broken valve spring and a dropped valve?...
Well a dropped valve would explain compression but not the oil huh? Also using a Gauge with the rubber cone and not a thread in. So middle two could just not have sealed all the way on the gauge. Chances on only 1 valve being burnt? I thought they all would burn, just like rings?
Btw. The dead cylinder is closest to the passenger side. Spark plug was deep brown but not wet. Others were quite lighter.
sure one valve could be cracked, or burned, if you had something like a cracked valve guide, or a crack in the head that also would explain the oil, don't condemn the rest of the engine until you know for sureQuote:
