Do you have specific per-cylinder compression numbers too? Without being there first-hand for the tests, I can tell you that your leakdown numbers look ok. However, your compression numbers look a bit low when compared with your leakdown numbers. For example, a brand-new engine can usually compression test at about 175psi. Compared with that, 143psi seems a bit low. Do you know if the oem procedures were precisely followed for the compression test?

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
