WATER IN OIL

[MIKE IN lINO III]

I checked the oil in the wifes Jeep and found a sludge consistant with chocolate milk. I will make the assumption that there is water getting ion the oil via the coolant system. It does not leak oil/water on the garage floor.

I saw a product called Steel Seal, It is supposed to seal up the leak. Any body have experience with this product or a similar product? Do products like this actually work?

I don't want to dump a lot of money in the vehicle.

Thanks,

Mike

Year, Make, Model, engine size?

Are we talking about the slimy sludge on the fill cap or was all the oil in the crank case frothy chocolate milk colored?

Are you losing coolant?

If you just found a little bit on the fill cap or a little on the upper part of the dipstick this can be normal. During the warm up process condensation forms on the inside of the engine. If it is not driven long enough to get hot enough to boil off the condensation than it will accumulate and leave that frothy slimy goop behind.

If you are loosing coolant and all the oil in the crankcase is frothy chocolate milk colored than you have bigger issues. knowing what year and what engine will help a lot.

As far as the sealers, if its a head gasket I have not had one work yet. We get a lot of customers who want to try the stuff and we humor them by going through the steps but to date none of them had made any difference. Band-aides don't fix problems they only cover them up!

Thanks Airjer,

It is a 1999 Jeep Gand Cherokee. I don't know the engine off hand.

The dip stick had normal oil on it. It was a little low so I opened the filler cap and that is where I found the chocolate milk. It was in the filler cap and down the spout.

Her car has been stitting more than normal, I will have to check the coolant tonight.

Hopefully it is just condesation.

As long as the oil in the crankcase is good than its the condensation. One thing you can do is get it out on the freeway for an hour or so to help boil out the moister in the block. Typically short trips are to blame for this problem but there can be other issues.

If I remember right the 4.7 v-8 has that obnoxiously huge oil fill cap. on the passenger front of the engine. Just about every one of them have a little of that sludge on the cap or under that diverter thingy for the PCV valve.

You are correct.

Like I say, it currently doesn't get used as much as before. Kind of freaked me out when I opened the cap........This is all I need.

Another quick question.

When she bought it used, the idle would race when started cold. It would race up and down very noticably. She brought it in and nobody could find anything wrong with it. I noticed that it doesn't do it anymore. Any ideas? I'm glad it doesn't race anymore but I think it is strange it would just stop.

You got me on that one!

Fortunately we have a lot of guys who know a few things about the automotive world. If they have a thought I'm sure they will chime in and let you know!

I see that there is a bulletin # 18-012-02 for computer update for cold engine flare for the 4.7 engine.
