I pulled my valve cover off to paint cover and do a gasket.
Please see photos below.
Is this a excessive amount of h2o on the lifters?
There is no water on the cover or head.
4.0 auto,109k.
JUST overheated,light just came on and shut down.
Blew radiator,on order with other parts.

There's really no such thing as excessive when it comes to water mixed with oil. It's all bad. You don't want water in your valve cover at all. If you do, hope it's a head gasket and not a cracked block. Water in oil can cause bad problems.

I thought it might have been a lot of condensation.

Do a compression test to see what happens. How is it running? Or a coolant pressure test.

It's hard to tell from the photo, but, oil looks a little like chocolate milk. Do you run coolant or straight water in your radiator?

Blown head gasket over-pressurized the cooling system and blew the radiator.

And/or the head and/or block is cracked.

There should never be any mixing of coolant and oil in a healthy engine.

Much more diagnosis and testing is in order.

RDR,I have the cooling system pulled apart,so we did a cold compression test. All 6 cylinders read 110 lbs. I know that reading is low,but remember the engine was stone cold.
50/50 mix coolant & water.
Firestorm, after inspecting the radiator,it was falling apart. It was I think original and leaking from 1 spot in passenger lower section.
The jeep just started to overheat & was shut down in the driveway.
The only leak was from the rad upon immediate inspection.
Jeep was running great!
Brakes froze & son drove it 3 miles home.
Milkly substance is at bottom of oil in bottom of lifters. Photos are after I stirred up oil.
Can not see any crack in head with valve cove off. What's next?
How about a oil test?

You know the radiator is bad. I'd replace that. Then do a coolant pressure test. See if you can find leaking. I'd keep valve cover off while doing the pressure test. Some cracks are hard to see unless it's hot. But, you'll see green coolant squeeze up through the head into the valve cover area if it's cracked.

Bottom line, repair the radiator and see if the system can hold pressure. I know coolant can start to get expensive when you replace it over and over. You could re-fill the system with distiller water for the pressure test. If everything checks out, then drain and re-fill with coolant.

But, firestorm is probably going to be the expert here. Let his advice overrule mine.

I live in an area that has dewpoints in the 60s and 70s most of the time. In other words, very high relative humidity.

I have never seen water pool in rocker arm pockets in a healthy engine around here.

Modern oils have to have a lot of water in them to look like that.

madmanmarty

Firestorm, I live in PA with high humidity also.
But I want to be very clear with what I found in the rockers.
It was not water.
It was a good amount of oil on top of a thin layer of "milky cream" on bottom.
The photos are after I stirred the mix.
What I did then was removed all the oil and milk from the rockers.
I used brake cleaner being careful not to get any anywhere else.
It is wiped thoroughly clean.
Jeep has been sitting for 1.5 weeks.
I have a Blackstone Labs test coming any day.
What are your thoughts on the amount of milk,if it could have pushed thru at overheat, and next steps to take.
Thanks,Marty.

May not have been the best idea.

Why not. I limped mine 12 miles.

It's 2015, there's these new fangled things called flat beds. When you call on a phone, a person actually comes to you and your disabled vehicle.


They then load the the disabled vehicle on the flat bed and drive the disabled vehicle to another location. This prevents further damage from occurring to the disabled vehicle.

Cell phone coverage starts 500 feet from my house. I was out that direction. So yeah.
