Does a compression test tell you the same thing as a leak down? If not then please educate.

Compression test gives you what the cylinders will build in pressure,,a lead down test will tell you the condition of the rings and if the valves are sealing properly..

whataride

what is the minimum amount of air pressure that should be used for a leak down ?

OldSchool

Use 100 psi.....it makes the math really easy!

whataride

does less pressure say 32 psi not provide sufficient results
