I'm saving the turbo for the buggy......I just want to get back on the trail. Summer is a tough time to be rebuilding stuff.

Hmmmm.....the more questions that I have answered, the more form up in my gray matter.
Will Renix intake and exhaust manifolds bolt to an HO head? Are the ports different shapes? Bolt patterns different?

curious, how far away are you on that buggy?

Well, the rear got linked up, the tub is stretched, the frame extended (4"x 2" x .120"), drivetrain done (4.3 TBI, SM465, Dana 18), axles are close (rear: FJ80 full float, 13" disks, electric locker, front D-44, ARB).
Still needs a cage, fuel cell, wiring, front links and steering.

99 block
The 99 block has all the prior bolt holes and even one for the knock sensor. The header ports are similar and any header should fit - the tubes are bigger than the ports in the head.
The Renix manifold should fit - people have reported using it as is - but I'd try to match the ports by moving it down slightly.
Otherwise the 91 - 95 HO manifold has the bolt holes for the EGR
and I doubt that any Government Employee at the smog station cares much? Or would notice!!

Hmmmm......OK compression tested my motor this weekend (warm motor, all plugs out, very good compression tester), and this is what I got:
1 125#
2 136#
3 147#
4 145#
5 132#
6 127#
What do you all think of this? The motor had very little water in it, which is a good thing. I really think the main bearings are shot, but it seems like the cylinders may be salvageable, according to the numbers. Maybe a .030" overbore would do the trick, and keep the thing cool in the hot California sun?
What was the compression supposed to be on a 1988 4.0?

15% spread not bad for a 200k motor, a 10% spread is typical of a decent running engine. Just change the oil and run the thing, worry about a rebuild over the winter. Why do you think your main bearings are bad?

The clickety-clack that is a sure sign of main bearing outage. It's not horrible, and it still makes 60 pounds of oil pressure under load and 40 psi at idle.
Lately, the rig just felt like a dog. The o2 sensor was going bad though, so a new one might help.

yeah clickity clack is a sound better reserved for trains. A stethascope (sp) might be a good thing to do to make sure the noise is from that general area. It would suck to install it in the phoenix and then take it back out to rebuild it later on.
If its any consolation I get 20 psi at idle and about 40psi a little higher up. Not that my motor is a super fresh by any means.
