Anyone know much about Jeep 4.0 L6 engines?
#1
It is in a 91' cherokee. It pushes about 180 horses, it also has 176K on it, it runs fine has one oil leak. which brings me to my questions.

1. I have a new "o" ring for the housing that goes to the block where the oil filter mounts, it has one bolt that i can see. its a 5/8 head, I have tried and tried to get this to bust loose to no avail. i was wondering if this is a reverse thread on this part, or what i can do to maybe get it off without damaging it?

2. If I wanted to get say a supercharger and do a rebuild on the engine, would i be safe to maybe bore my cylinders out to maybe .05 over or is that too much, i would have a beefed up head of course new cam, race valves all that. I guess the real question is how far over can one bore the cylinders safely?

3. I have some sag in the rear end suspension, I was looking at the add a leaf kits they are pretty cheap. would this do okay with a 2 or 3 inch lift installed later, or should i just get the whole enchilada for replacing the rear springs, that ups the costs a bit but is it better to do that when i plan on a lift kit later on?

Just some questions burning me up, the oil gasket is the one really on the hot plate for now. thanks in advance,
