Engine at normal operating temperature
Compression #1 #2 #3 #4 110 100 100 100 Compression after 3cc's of 30 wt oil added to each cylinder #1 #2 #3 #4 110 102 110 110 Vacuum was steady at 16 in hg. Relatively new plugs look a little foul. It looks like all cylinders could be higher. However, this is a brand new compression gauge so I have no readings taken previously and I have no way to know if it reads high or low. From what's been explained to me it appears that 3 & 4 have some ring problems because the addition of oil improved the compression. I also suspect some valve guide problems but it wouldn't hurt my feelings if you guys told me I was way off base. So, wade in and tell me what you think. Dave |
