May 1, 20197 yr #1 I've bought used 2010 FG turbo motor ( roughly 100,000 KM), did the dry compression test and the result was low in 2 cylinders 170 and 190. (could it be the engine was not running for months)? afterwards did a wet test and it showed 210 across all cylinders evenly. just Wondering what is average com test result for this things.
