At normal temp the correct reading will be gained. If low compression on one pot then add oil. If the reading gets better then its most likely worn rings. Am I wrong in this?

The blurb that comes with the compression gauge probably says so... but why bother when the quick, easy (and far more effective) check for blow by is to remove the oil filler cap while the engine is running. Takes about five seconds, and even if you're deaf and blind you'll still be able to smell it if it's bad enough to show up in a compression test. :) -- John H |
