I would hardly call 110 low. The fact that it is uneven is a problem. Check the exhaust valve on the cyl. with high compression, to make sure it is opening.

When checked with engine cold it is much higher. why is this? My main question is I was told to do a leak down test. I know what gauge to get but thats about all I know. How much pressure do I put in and how can I tell if it's the valves or rings leaking down or what else can be learned from this test? > > Thanks, > Chip > |
