Oil in radiator. (1 Viewer)

[Tommy Shumpert]

So, flushing the radiator this weekend and noticed that I believe oil is getting into radiator.
Head gasket I presume....
Anyone ever see this before?

 

[Tommy Shumpert]

Yea. Made a damn mess too! The drain in radiator is blogged.

ewww, definitely check the oil for water contamination.
Has it ever had stop leak in the coolant? Could be residue from that. Bars leak looks a bit like that.

I'd check the oil, too.

 

[Tommy Shumpert]

Oil looks just fine
Oil pressure good, and truck runs 180-200 deg.

Does stop leak feel greasy?

Let it sit over night in a glass jar and see what it separates into.

It looks likes oil but I would think your oil would be contaminated as well.

The bars brand with the pellets is quite an oily solution.

Yes, as noted above, Bars Leak feels oily.

Thanks for the help!

Also check the oil filler cap for white sludge. Can be from water in the oil but not always.

Clean. Don’t see anything down in valve cover either.

Sucks not knowing the background of the car....

 

[pithicus]

Clean is a good sign, You may be lucky!!

flush it real well and add new coolant. See what it looks like after a while. If you let your motor sit for a day or two and slowly remove the drain plug so it just barely comes out you can clearly see if any water is in the oil pan. Water sinks to the bottom.

Hopefully just residue from something the previous owner did. [bars leaks or head gasket replaced without flushing the coolant after]
Anyone had oil to coolant only one way? I guess it's possible .
Let us know how you go Tommy.

Great idea. I will give that a try. Thanks

I’m hoping that’s the case. Fingers crossed...

Hi, Fill again, run for several days ,flush again ,probably will need a second flush to clean it out anyway. Use your heaters to flush them out too. Mike

Has no one mentioned the possibility of a failed oil cooler yet? Does your FJ40 have one?
