I have read up on how to do a leakdown test. But it never tells how many PSI your supposed to fill the cylinder with??

I was wondering what most of ya'll do as far as how much pressure ya'll pump in there.

thanks,
John

 

It's usually around 80-100psi.

 

100-120.

 

I realize this is an old discussion, but it reflects an important, often asked question. Many leakdown testers are questionable, which makes an accurate test impossible.

Here's a 'how-to' for constructing your own, accurate tester. I'll make a writeup on the testing itself in a different discussion:

I stick to around 80 psi. but not under 80.
