I know once I post this 2.0 motor for sale, I'm going to be asked a bunch of questions (no, I will not take trades (IMG:style_emoticons/default/smile.gif) )
Namely compression or leakdown values.......compression I can do myself so that is a no-brainer (famous last words) Should I bother with trying to get a leakdown test for a Type IV motor??? |

I favor compression. If the comp is low in one or more cyls, the leak down can identify/isolate the problem. If the motor has good comp numbers, there's no need for a leak down. Another benenficial leak down is for the total engine. This finds vacuum leaks in the intake. You can do this with an intake valve open and the intake sealed. But you do this with a vacuum, not pressure. I belive NASCAR does this on restrictor plate motors. If they find a leak, they tear the motor down. A leak there is speed.
