Project: "Rigor Mortis"

[4.3LXJ]

All this talk of 6 wheels, he is just forcing the hand

[Pookapotamus]

Absolutely zero compression on number 1, all others are 175

[Pookapotamus]

And here is why!!

[Pookapotamus]

I can see my oil ring!!!!!

[4.3LXJ]

Did you suck something down there, or is that just a lousy casting?

[Pookapotamus]

I think, that the upper ring broke, which broke the top of the piston, it looks like a piece of ring bounced around inside the chamber, if you look at the pass side of the piston there is an indentation, looks like a ring mark. Why this happened I have no idea! Never heard anything.

At least I'm lucky, not even a mark on the head or valves! Slight marks on the cylinder wall but should hone out nicely.

Ouch, man that sucks to see... Hopefully that will clean up nicely and not too expensively..

[4.3LXJ]

Man, you have had so much bad luck with the rebuilds

[Pookapotamus]

Yes is should clean up nicely, going to pull the motor, pull the tranny, maybe go roller rockers, possibly do the new voodoo cam, other upgrades while I'm in there.

[Pookapotamus]

Ready to pull the motor. Been researching cams, comp cams says it is computer controlled compatible, does this really make a difference, it's not like the xj comp can do much? If I am degreeing the cam should that not be enough? What's the difference??? Anyone know?

[Pookapotamus]

Also found a oil filter relocation kit that uses 2 PH8A's

[4.3LXJ]

Degreeing the cam adjusts the torque curve. In a car like my 05 Subaru, the ECm adjusts it to make the torque curve almost flat. IIRC, retarding it makes more low end, advancing it makes more top end. You might want to check with Tony. I think the cam he had so much trouble with was a Comp Cam

Bummer to see Mort down but I'm sure it'll come back better than ever. I love your Jeep. Time to slap a 4BT in there...

[Mudderoy]

Crane cam

[Pookapotamus]

Jake, yes the 4BT would be cool, but I dont know much about diesel, thats why I chose the stroker, I can fake my way to fixing it!

Well I contacted Lunati, Gave the tech Morts' specs and what I use him for, and he confirmed that the cam I was looking at (10680701LK) will work even though it is not comuter compatible and in fact is the cam he would recomend for Mort.

Hello Summit Racing? ya its me Pook again, you guys need a good kidney??
