Compression numbers question?
Anyone have an idea as to how much lower compression test numbers are on a cold engine vs. operating temp? I ask b/c the salvage yard tested the engine that I'm going to pickup, but they were cold numbers as the engine is already out of the vehicle. Luckily the numbers are all relatively consistent, but sounded just a tad low to me in the mid 150s.
