Coolant in oil...chocolate milk shake?!

[Deleted]

Alright lads...here we go again. Just when I thought I was done with this jeep...NOPE.

I flushed the and replaced the old brake fluid yesterday. Today, I thought I would treat myself to the reward of driving the jeep. Everything seemed fine: she started up immediately, had great oil pressure, idled fine, and even the brakes worked! I took a few spins around the neighborhood...maybe 1.5-2 miles. When I pulled into the drive, I opened the hood and was just looking and listening to make sure all was fine. That's when I noticed the drip from the bell housing. No big deal (although it was a bit more than my own jeeps do). I placed a pan under it and went back to looking at the engine. When satisfied, I drove it into the garage and shut her down. I picked up the pan and that's when I noticed the chocolate milk oil. I stuck it under the parked jeep and collected more of it.

I then opened up the filter canister (it was the same) and then drained the crankcase. All chocolate milk.

I opened the radiator, and it appeared to be at (or at least unnoticeable in difference) to the level that I topped it off to yesterday. So, what I'm saying is that if coolant leaked today, I couldn't tell-the rad still looked full.

BACKSTORY: when I pulled the head last week, I was surprised not to have any coolant leak out when I removed the temp gauge. The head was bone dry. I opened the radiator cap and it was crazy low. I must have filled it with almost a gallon of fluid yesterday.

When I replaced the head gasket, I used a new gasket and sprayed both sides with the copper spray. I used nonhardening permetex sealer on the threads of the bolts. I torqued them to speck and then re torqued after running it to temp. Also, the original head gasket appeared to be failing between cylinders 2 and 3...almost like it was disintegrating in the middle, not on an edge.

The first time I ran the jeep, I forgot to refill with coolant. It ran for a few minutes and got to almost 200 degrees before I shut it down. Today, while driving, it stayed around 170.

I don't know why it was missing so much coolant when I received it. The owner said he changed the oil (3 years ago) and had only driven it 10 miles since.

How much coolant does it take to contaminate 5 gallons of oil??! I really hoping the contamination was done before me!

Thoughts?

Hahaha! I don't know why that statement was so darn funny to me...but it was! Lol

Standby for chocolate milk picture...

Sorry. That was for Haines. Hopefully it will distract him while we get down to business.

Ok...so it's doesn't exactly look like the chocolate milk that any of us would want to dip a cookie in, but it seemed to be the accepted technical term for coolant mixing with oil. No, all the other crap in the pan did not leak out of the engine. It was already in my pan. I drained the crankcase and it all looked like this. It's currently in my community oil catcher tub mingling with other oils.

MHO, there was coolant in the bottom of the oil pan, or as you removed the head coolant spilled into the crankcase. The engine reached 200 deg. because you neglected to drill a vent hole in the thermostat and the head was air locked.

Now if none of the above is true, you may have a cracked block , you may have a bad headgasket .

I would flush out the oil pan, fill er up with fresh oil, you may need to change it several times to get rid of the water/coolant, and see what happens .

Here is a picture of the head gasket I removed. It appears to be failing between cylinders 2 and 3. Is this sufficient enough to get into the oil?

As for the thermostat, the owner said he had removed it sometime in the past. I didn't look to see if it was there or not.

I've already pulled the pan and cleaned it up. When I replenish the oil, do I need use new oil filters or since I'm will be dumping the oil I can save a filter?

[Deleted]

I wholeheartly agree with Master Lee!!!

Personally, I'd clean out the filter canister, and replace the filter, coolant and oil combination is really hard on bearings.


I'm sorry you're having all this hell, Bo, your luck is like mine..

[Haines Garage]

I agree with the Captain as well!
That #2 and #3 spot. .
But then again...
I know nothing about L134 cracked blocks .

[Deleted]

Tallboots, just take the hole filter contraption off and throw it in the trash can, it will protect the engine just as well there ...............WPOS.

Oh and don't forget , now your oil pick up is screwed!

Coolant in the oil = Bad or incorrectly installed head gasket, or cracked block . Just because it runs , does not mean it is not cracked!

[Deleted]

A blown head gasket will definately put that much water into the oil. If it was in the pan already, absolutely will look like that. Try the new oil and drill that hole in the thermostat if it isn't there. 1/16 is all you need. You'll know very soon if there is a crack or not. Signed Chocolate leaker

I am not being a Smart Ass,
So will a crack between 2 and 3 !
I have seen it many a time .
It's hard to work on old engines, anyone who tells you different is selling something !

[Haines Garage]

I think The Captain did a thread here about theT Stat !
But I don't think that is what's going on here.

Ummmmm....no good deed goes unpunished, right??!!

How much coolant does it take to turn 5 quarts of oil into that 'stuff'?

After my short ride today, I checked the radiator and if some coolant went astray, I couldn't tell because the level looked to be about where I had filled it to.

[Deleted]

What the Hell Tallboots! , so you do all this work on this engine and you did not change the oil before you ran it! . WTF, I would fire you! .

the crack is common between 2 and 3. my f heads all have it. put on some permextex number 2 where that gasket was eating through (on a fresh gasket) and that should hopefully seal the spot.

[Deleted]

Schimmmmmster. My F head had it as well. I V'd the crack a little and JB welded mine. Then some bars leak and a hole in the T stat. All is well. No more issues.

I am going to ask a perhaps dumb question here Lt.
You did use a New Head Gasket.....right?

It would be a dumb question for Lee. For me, well within the realm of possibilities. The answer is YES, I used a new head gasket.

I picked up more of the details from the past. Here is how things fit into the picture:

• 3 years ago the oil was last changed. It was normal, used blackish oil. No indication of coolant mixed in.
• I tried to do a cooling system pressure test. I used the loaner tool from OReillys. It was too small to fit properly on the radiator. I managed to make a seal 4 times, but it only lasted for about a minute each. However, for that minute, it held its pressure.
• 3. I did an old fashioned cylinder compression test. Cylinders 2, 3 & 4 had 100-105 lbs. cylinder 1 was 0. However, in the beginning, I knew this was the case when I was trying to get it to TDC. I blew a small bit of compressed air into the spark plug hole and could hear it bubbling in the crankcase.

WHAT if the non hardening permetex used on one of the head bolts didn't seal the coolant. Could it seep up the bolt and into the combustion chamber? If so, would that not show up as a gasket failure in the compression test?

I guess I'm reaching now...

[rudycon]

If #1 has no compression, you might have found your head gasket leak. fill up the radiator so you can see the coolant, start engine. Look for bubbles.

No bubbles? Stop engine, change oil. Who knows what happened in the 3 years it sat. It was wet enough to seize up the engine at least a little. That last jeep trip 3 years ago could have been through the deep part of "CJ canyon" and water has been in the engine since. You didn't see it because it separated out while sitting 3 years and collected at the bottom of the pan below the reach of the dipstick.

Moosy, if it is currently leaking up the headbolt, it would come out on top of the head at the nut. To get into the chamber from the stud, it has to be another blown headgasket, warped head and the gasket didn't seal, or a crack. My money is the water was there before you did things from the blown headgasket. Should we all place bets on this? We haven't done that yet here. Oh oh, on line gambling with Jeeps. Oilly
