Compression Numbers

317 Views 2 Replies 2 Participants Last post by  Orlando_87GN
Just checked the compression & all cylinders are about 135-140 except #1 is 130 & #3 120. I do have a slight ticking sound by #3 as well? Any ideas?

Ideas anyone??
I don't trust compression testers any more. Rent or invest in a leak down tester and you will be provided with more accurate readings that will tell you more... like where the problem is... rings, valves or headgasket... I think they are less than $100 for a nice one or you can get creative and make your own using (2) regulators and (2) 150psi gauges... powersix :)
