Default Re: Leakdown Testers

You can leak a motor cold or hot. Just do the same thing each time. A warm motor should leak alittle better the cold. If doing cold just spin the motor over a few revolution to make sure you have some oil on the walls. Certainly under 10% mine usually leak 3 to 5% when fresh cold
