So,,,,,,,,,,,,,,, you can make an informed opinion about automotive power
plants based on your level of knowledge and experience. The same thing
should be true about your mouth. You may need to discuss it more with the
dentists to see what the decisions are based on.

Do you deny that 4 different automotive shops would give 2-3 different
opinions based on the above scenario? Hypothetically, lower the reading on
the lowest cylinder to 480 psi. Now you will get a wider variation of
choices. I would not tear down the engine on my road car for a 10%
compression difference. If I was racing, though, I probably would. If I
was running a hi-po street engine, I might. Even at 470 psi in the worst
cylinder, I would hesitate to do a tear-down on a stock engine. I have two
cars with 3-cylinder motors. If one cylinder was down in compression by
20%, it would get torn down. If one cylinder was down 20% in my V-8, I
would hold off. Lots of choices based on what was normal for the engine,
how it gets used, what is intended for the future, and what I am willing to
put up with as time goes by.
