Posting for a friend with a 1984 CJ, 258, std. that he's rebuilding.

What's the spec for cylinder compression? He's getting 160 across all 6
cyls, which sounds pretty good from here.

He's putting a new fiberglas tub on his Jeep and might have a windshield
frame from a Wrangler fall into his lap, which was offered to him as
having a better wiper system than the CJ. Will this fit the tub without
causing problems with his hard top? I gather that there may be bolt
hole and vent issues, but since he's putting a new tub on anyway it
might not matter. Will his existing scratch-and-chip-free windshield
glass fit the Wrangler frame?

Thanks.

 

Don't know about the windsheild, but 160 accross on the engine sounds
good, sounded good on mine too till we did a leak down test, 15, 18, 22, 40,
49, 15, 20, not so good

The windshield frame will work, but you will have to cut vent holes to match
the defrost vents that CJ's use. Not too hard to do, and if they are ugly no
one will see anyways. You may have to mix and match wiper motor arms to get
it all to work as well.

How is a leak down test done?

The one done on small aircraft engines involves pumping 80PSI into the
cylinder and reading the remaining pressure off a gauge. The results are
given as 77/80, 76/80, 79/80, 80/80.
