Uh Oh:coolant getting into oil.
 

I have a 05 LGT, with160k. Was changing the v.c. Gaskets today and doing an oil change and found that my oil was very milky. The car does not overheat, and no power loss. Can not seem to figure out where it's coming from.

I would be looking at the head gasket.

Wouldn't I have oil in my coolant with that?

Not alway's.

Max, are you leaning to head gaskets too? Shouldn't I be overheating. I did change oil cooler oring. And I checked the cooler today it was a hair lose so I tightened it up.

milk oil = water mixing. get a headgasket tester kit at an autoparts store, it's quick, cheap and easy to do to test for exhaust gases in the coolant.

Any coolant loss...?

How far is your commute? If it's short it could just be that you're never getting it hot enough to sweat out condensation from the night before which ends up emulsifying with the oil creating the milk appearance. What's it look like on the stick? You could always send a sample to Blackstone and see what's really in it.

Beat me to it.

I drive about 40 miles round trip, coolant level is still good. No smoke. I'm from Tennessee and lately it's been Latoya rain and sub 40 weather. But drive about 200 miles on new oil change and no signs of water on the stick.

Keep an eye on the oil every day or two.

That's my plan, I'm hoping its either condensation, or that oil cooler being loose.

What size socket do you need for the cooler bolt?
Thx

24mm deep I got mine from Harbor Fright, comes in a kit for about $20.00, or it may have come from Northern tools.
