[Healeys] 4 Cyl Compression Measurement

[Alan Seigrist]

Just another note on this:

compression is more or less self correcting once you get over 500 rpms, so
regardless of how good or bad your rings are, you will have plenty
compression for the engine to run normally, even with bad rings or a scored
cylinder.  It just may burn oil.

Main thing is to make sure the numbers are all very close, that helps reduce
stress on the crank and helps your car run smooth.
