TR2/3/3A Checking a cylinder head with a straight edge to see if it's warped?

Share this page

If you put back the same questioned head, unmachined, on the same liners with questioned FO8s and you still leak, you will still not know where the leak is. If you plane the head and it still leaks, you will eliminate the head as culprit. You may do a second head pull and the FO8s when you didn't have to.

What is your theory on the following; 1. why was there no coolant/oil in the cylinders when I pulled the head? 2. is it possible to have a head gasket leak if there is no obvious damage to the gasket. If a couple of cylinder head bolts had loosened over time is it possible that internal pressure at that spot would spring a barely noticeable leak between the head and the block? But I don't see how that "type" of leak would cause the coolant to dump into the crankcase? What am I missing here?
