 This seems like it may be a good topic.

I was getting an undue amount of crankcase pressure at Topeka.(Just now trying
to find the time to sort out)

At idle there are absolutely no engine oil leaks.  At 60-100mph the oil is
being pushed out in huge amounts. at every possible location.

This occurs in spite of otherwise very effective vacuum system we have used
with great success on the TR4 #197

Have never done a leak down test in all of these years or had one done. No
experience at all.

Results:  100/85   100/80   100/60   100/60

Pretty dismal readings if I did it correctly.

Head is off and new rings to be installed.

The benefit of FOT experience and knowledge would be greatly appreciated.

Thanks!

JOE A.
