Yup, that was my concern (the block I have being FUBAR). I might buy JUST a block, but I would like to limit downtime as much as possible - buying a junkyard motor, rebuilding / stroking that, and then swapping 'em. Possibly turning around, tearing down my old motor and reselling it once...

Well I was looking at doing the DIY stroker on this motor at some point, somehow now I figure it would be easier to score a parts yard motor and rebuild that. I was thinking a healthy .030 or .060 overbore with a 258 crank, rods, and pistons. Possibly a new cam, though the stock grind would...

Negative, it cleaned up real easy, I used pipe cleaners and really went to town on it - there was no sludge buildup.

Could be, but I did that only about 4k miles ago. Used carb cleaner, and I really didn't get that much sludge out. That much have built up in such a short amount of time?

Ok, this is actually what I was thinking. So I guess I wasn't wrong then, cool. What would it take to swap in a newer (for example a '97 OBDII) engine into a '94? Would this require an ECM swap, or would I just reuse sensors? How would the ghetto rigging work for the electronics?

I wanna keep my AX-15. Would a renix block with a HO head be what I'm looking at doing? I hear the major difference between the HO and the non HO is the head, so that would be a more or less duh answer. The difference between the AW4 and AX-15 blocks may be the starter, however a visit to...

I understand that it is relatively few miles for a 4.0 to crap out. However, this motor seems to have been poorly maintained during it's previous ownership (the reason I draw this conclusion is that the diffs and t-case either had the factory fill of fluid, or they were flogged) and I wouldn't...

It's a CCV setup, I did the madxj style update with the 2000-'01 parts toi reduce blowby in the air filter. It's been through a valve cover gasket and two oil pressure senders in the last four or five months, the major leak I have right now may be another sender. Also my oil filter adapater...

Yeah, I figured. Has 168K on it right now, I bought it with 147K on it when it still ran strong. It really started to go downhill right after this summer, where I logged about 12k miles in 3 months, between round trips to AZ and OH for SAE Mini-Baja, and almost weekly round trips from home to...

I think my 4.0 is dying, in need of a rebuild or replacement. It's a '94 HO in a Sport model, with the AX-15 and NP231 behind it. I go through plugs about every six months - it just loses power on the highway and can't sustain speed. I usually end up with the first five plugs on the "slightly...

Crap, I've been hijacked. Actually, the problem is fixed, and this is pretty funny. Carry on, and thanks again.

Well, I just changed out the oil pressure sender. Cost was $24.49 plus tax. Five minute job, no kidding. Seems to be runnin' fine, sans leaks. We'll see when I drive back to Chicago next week. Tightened my valve cover as well (three or so bolts were a bit loose). Thanks guys, hopefully...

Hey Runnin' On Empty! I think you were right. If I'm not mistaken, there should be NO oil on the one plug that comes out of the oil pressure sender, right? I pulled mine and hit it with a flashlight, and sho nuff there was some oil on it. You mighta stopped me from barkin' up the wrong tree...

Okay, it's dark now. I'll look in the morning. It was a minor amount. . . but I'll check that, see if I can't fix that and return my rear main / oil pan gasket for another day. Post in the morning with results.

Good God that's brilliant. I'll check it out, great idea. Give me something to do until I can haul it into the mini-baja shop tomorrow.
