Thanks guys!!

Head gasket problem? Cause??

Since oil is lighter than water, any water in your crankcase will settle to the bottom. After th eengine has been sitting overnight crack the drain plug and see what comes out.
At least you can rule out a bad intake gasket on the 6.2L..
I doubt it is water. A quart of water would be at the bottom of the pan, it would get sucked into the pump and spread everywhere. It would be a mess. Do an experiment, put a little water in a jar that is mostly oil and shake it up, see what it looks like - the oil in your engine would be the same.tRustyK5 said:
If you have a block mounted fuel lift pump, it could be bad and be leaking fuel into the crankcase.
Just reread your symptoms, passenger side blue smoke and overfull oil pan. Think it might be overfull enough that the crank is hitting the oil and slinging it up on the cylinder wall? The crank turns that way.
Because the pan flattens out as it gets above the sump, plus one quart on the stick could be a lot more than one quart. Drain it out and see if it makes a difference.

Not a bad idea...I'll try it a bit later. It's been sitting without running for 30 or 40 hours so if it is coolant i should see that come out first. If not, maybe it is fuel.

Would that work with diesel? I don't have much experiance with the stuff, but my dad who has a diesel Jeep Liberty has told me you could hold a match up to diesel and it wouldn't burn easily.smalltruckbigcid said:here's an oldtimers test for fuel in the oil. Check the oil and take a lighter and try to burn the oil on the dipstick. If it burns easily thats supposed to indicate fuel in the oil. If it doesn't burn easily it should be normal. How accurate is this test?but it is cheap fast and easy...

Easily is the word here, diesel won't burn easily as in it won't catch fire from a small flame, but with a lighter heating it enough it will burn.
Oil on the other hand will take way more flame to burn, it will also eventually burn.

The '82s had the high nickle content. Most likely it is a gasket problem.

Just drained out about half a quart, and it seemed a little globby but black. I had a good look in the drain pan and at first it appeared to be nothing more than dirty oil. No smell of diesel fuel. I slowly tilted the pan one way and then the other to see if anything wanted to separate and then saw a line of bright green in the bottom. Don't ask why or how but the oil is still black and never showed any signs of that milkshake goop I expected. There is a quart of anti-freeze in the oil, and it got driven for three days like that and there is no visible clue on the dipstick.
No doubt it's a head gasket problem now.

Well, at leat you didn't run it for six months!
You gonna do a writeup on the head gasket change and ARP stud install??

Sure, why not. I definitely don't have Max's diesel knowledge, but I will take some pic's and write a bit about the whole thing. I'm going to wait until we get moved into the new house and do it there. Starting on this Friday I'll be on vacation for 2 1/2 weeks so i should have plenty of time to do the job right.

Damm you caught that early. Looks like fun is in your future.

I had some symptoms that kinda screamed "head gasket". The smoke was one thing that I could probably have ignored for a while, but I also had the truck hydro-lock a bit on me. At the time I thought it may have been an injector dripping into a cyl with the piston near TDC (after shut-off). Now I know it was coolant.
I had my wife try the key while i watched and I could see it trying to turn over ever so slowly. About the time I was going to tell her to stop (maybe 3 seconds) it got past TDC and started.
The repair will start the first week of July when we're moved into the new place. I'll just rent a truck for moving day now. I rented one this afternoon for removing brush, and blackberry bushes. I have to say a 14 foot moving truck easily holds 7 or 8 times the amount that a pick-up does...so in some ways it was OK. One trip to the dump instead of 7 or 8.

How did the move, vacation, and wrenching on the head go??
Move and vacation went pretty good...we were so busy everyday it just seems like a blur now.
I just started wrenching on the pick-up a few days ago. I have one head to remove...then the cleaning, checking and re-assembly begins. Hopefully I'm feeling a bit more energetic tomorrow after work. I got the passenger head off and as usual I can't really see any 'smoking gun' as far as visual cues as to exactly where the problem was. Pretty much had to be #4 cylinder though, because it hydrolocked itself right before I tore it down and #4 was pretty much right at TDC and I know the problem was on the passenger side.
Passenger head looks good though, no cracking I've seen so far, valves look good too.

since you guys are on this. not to hijack, just wondering. friends got a 91 sub with a 6.2. everything seemed fine. first ride about 20 min. water all over under the hood. water bottle was full. head gasket? thanks
If the bottle was full and the radiator was low then yes it most likely is a head gasket.84CUCV said:

Last time that happening to me it was the filler neck on the radiator - it wasn't installed well from the factory and seperated at the junction with the radiator. Were you able to see where the water was coming from?
