Rebuilding motor, need suggestions

**scheides** · 02-16-2013

Took a look today, results are kinda screwy:

Compression: 130 110 86 121
Leakdown: 18% 23% 33% 20%

This is using my cheap harbor freight leak down tester, I usually remove about 10% from the leak down results.

Edit forgot to add: leak down on #3 was *really* hard to tell where it was going. Maybe rings but sound in the valve cover was ever-so-slight.

I hope a beater dsmer doesn't hope for those #. 1 of those #'s are within the serviceable limit.

But not burning oil between oil changes that's a different story
