Thanks to everyone for your help.
I checked the oil last night again and its really clean. There is , however, a little bit of "milk" at the tip of the dipstick, but very little. The rest of the dipstick has fresh oil appearance from when i had it changed a month ago. Very strange. No loss in power, no over heating, no tapping, just this litle bit of milk at the very tip of the dipstick, thats it. no antifreeze leaking on driveway either.
very strange....

You seem to be a 'proof is in the pudding' type and since the rig is running fine, you're golden. If that is the case, I'd keep an eye on it for sure. I had a Saturn (not my fault, I married into it) and the head cracked shortly. I didn't care much for it, so I did the shade tree head gasket swap hoping that would fix it, but I was wrong. Since the car wasn't worth a new head to me, I buttoned it and used it as a trade in (full disclosure) on a better rig. All this to say that even though there was water in the oil and oil in the water, there were no leaks and no loss of power. If you didn't look at the fluids themselves, you'd never know. That being said, performance may be a poor indicator of cracks or gasket issues.

Also, it is odd to me that just a drop of water got into your oil and that is the end of it. It seems that either this is bubbles as previously indicated, or the beginning of a bigger problem (no jinx). Just my .02 of course.

It is possible for a little water to get into the oil from the intake via the PCV valve. It sounds like your fine though for now, but I would definitely keep an eye on it. Check the oil regularly for any discoloration and keep an eye on the radiator fluid level. The simplest 2 things to check, and easiest ones.

another easy way to check for head gasket failure is to (with the engine cold) take off the rad cap and start the jeep if there are any bubbles visible in the coolant theres a problem

Well, it's ironic, last night our 92 Cherokee blew both of the low-beam headlamps at the same time, so today while I scouted out WHY I checked the oil and low and behold, I have the SAME exact problem that started this thread. . .

What I have been doing since then is trying to locate another motor, because in my experience, as soon as moisture makes its way into the crankcase, the bearings are not long for survival. . . .

SO, even though, I just put two new headlamps in and changed the blasted drivers seat today, I have a tiny little bit of babycrap on the end of the dipstick. . . Oh bloody joy.

So the question is this. . . Anyone have any idea what motor years will fit into a 4.0 L HO from a 92 Cherokee (4x4, automatic). The only info I've found so far is that 92 thru 95 is the same motor. Right/Wrong? Help would be awesome. Thanks.

hi-jacking the thread, but I think he fixed the problem or it fixed itself. hahaha. I'm not sure but cant you put any I6 in there but use your intake and exhaust and sensors etc. I just put a 98 motor in my 96 that was out of a wrangler and I had to use my distributor, coil, oil press sensor, intake and sensors.....so I'm guessing you should be able to use most any year cause I think the basic block is the same. You can even use a manual motor cause thats what the wrangler motor was that I had. If you do there is one simple modification minus the swapping of the flexplate/Torque Converter and the Flywheel. I can tell you if you get a manual motor.

I also made sure of the swap with a local 4x4 parts store which would be good to do if I were you.

Most likely from sitting around a while. I would change the oil and keep an eye on it. But, if you oil looks like the picture on the first page then its more then just water from sitting.

i drove it a little today and it did not over heat but when i got home with the valve cover gasket i checked my oil and it was foamy and white foamy and it was not all the way up the dipstick so looks like a new head gasket.

I got my oil changed again and put that lucas stuff in and she runs really good. i think i just had a little bit of moisture in there. there is still a tiny bit of milk on the end of the dipstick, but she is running fine. that lucas stuff makes a big differece as well. really good stuff.

Probably wouldn't hurt to do a compression test anyway. Pull all your plugs out and disconnect the ground end of your battery cable. ground this somewhere on the frame. Also disconnect the fuel lines to the engine. One at a time insert a compression gauge into each spark plug hole and check the readings while someone cranks over the engine with their foot to the floor. The readings should jump up a lot for the first crank and then subsequently increase slower. Write down all the numbers you get but only let the engine crank until the for about four cycles. Repeat this for each cylinder and be sure to reset your gauge in between tests. If you find that one or more of your tests shows a substantially lower reading than the others, you unfortunately have blown your head gasket. I hope this isn't the case for ya man.

I get the little blob of baby crap on my dipdtick, too. My engine has good compression and runs like a top at 240K. Monitor it and keep up on your oil changes. It's always good to rat hole money when you can so if you're not, start doing it. If it's not broke, don't fix it. But, if it does break, you'll be ready.
