Oil in coolant

Yesterday while pulling a steep hill, noticed i was running a little warm, checked the antifreeze today and there is oil in it. Question is what are the most common causes of this and what should i check first? Thanks in advance.

Re: Oil in coolant

Could be injector cups. Just went through that on a truck at work.

Re: Oil in coolant

I am with the oil cooler o-rings having failed. It is super common. Also easier to fix. Then I would lean towards the injector cups as the second most common cause.

Re: Oil in coolant

Where can u find the whole cooler, I am having trouble finding it, is it a stealership only item, I bet it is high $. I have been told the coolers are a pain in the arse to get apart and back together right.
