Creamy beige substance on dip stick

Right at the tip of my dip stick I am getting a creamy foam....what could that be....is it something that I should be concerned with?

yes, i would be very concerned. usually that is an indication that your engine oil is mixing with the coolant. it can mean that your head gasket is going or some other issue. usually not a good sign.

could be coolant or even aerated oil....OP...what year/mileage is your jeep? Did this occur after a recent oil change? Any smoke out your tail pipe?

It's either a head gasket or cracked head. Either way not good.

It is a '93 with about 160,000 miles. It did occur after an oil change....I actually had dented oil pan....I replaced it and put new oil in. It was after that that I noticed the foam. It's not running hot and no hindered performance!

Also when I dented the oil pan, it threw a lot of oil into my air filter. I cleaned out the air filter housing and put a new filter in and after I fixed the pan, there has been no more oil in the air filter. Should I clean more of air filter "system"?

I'd test the oil for the presence of coolant first. if no coolant is present, you may have too much oil in the crank case..it can get whipped by the internals and aerated which can impair it's ability to cool and lubricate your engine.

Easy, your oil will look like beige milk shake.

That's probably bad dude. Possible head gasket or a cracked block.

$22 for used oil analysis at Blackstone Labs will tell you with 100% certainty if you have coolant in your oil. Or you can old-school test it. Get a spoon very hot with a candle and drop in a couple drops of the creamy oil....if it sizzles and splatters, then the oil has water/coolant in it....if not, then it's likely aerated oil.

My grand Cherokee did this. A lot of stop and go driving will do this as well

This is also common if you dont drive far. Over time moisture will migrate into the oil, if you dont drive far enough to warm the jeep up enough to keep the moisture out you can see this. But if you just changed the oil then i doubt this is the problem.

True but that is more common to find under the oil fill cap. That's any vehicle not just a jeep and is normal. Water mixing in with the oil is not, bad head gasket or a cracked head.

A bleed down test on your cooling system will tell you if you are losing coolant inside the motor. It can be as simple as excessive condensation inside from not ever getting hot enough to evaporate it out. Are you losing coolant out of your reservoir?

I just cleaned out my CCV and drove it about 25 miles and when I checked my oil, all was good.....absolutely no creamy substance. So, either it was condensation that was burned off or it was the CCV. Thanks for all your help....except for those that made me freak out and think my head gasket was blown!!

I dont think the intent was to make you freak out, they were just answers to your question. Mine turned out just as those answers suggested. Im 4500 miles on a new engine now. Glad yours turned out different. I was going to ask if you are having to add coolant. I chased a disapearing coolant issue for almost two years before the engine finally let go. No evidence in the oil over that time period at all.
