Oil has coolant in it

[Dakota Biddinger]

So I finally got my car running. The first legit startup goes good, but then I go and look at the engine once I turn the engine off, and smoke is coming out of the valve cover. I start looking at the engine and look towards the right side at all the pulleys and tensioners, and I see that there is really milky oil that dripped onto a tensioner. So I then check the dipstick, and it has milky oil on it. Then I took the valve cover off and all the oil was super milky. My friend that pulled the engine said it ran good before he pulled it, so I'm wondering what it is? Head gasket is an obvious suspicion, but somebody on here said it could be a broken oil cooler causing the oil to mix? Also the engine had a 20g on it when it was pulled and now has the stock 13g on it

That sucks man...if you want to check you oil cooler it's easy to rig something up fitting wise to check pressure in it and you could use a regular air compressor for it. Cap one end obviously and pressure the other and see what happens. Obviously if it tests good then you know more than likely what the other failure is. Good luck!

A compression test will most likely tell you if it's the headhasket.

And I got confused about the turbo. It had the stock turbo on it, and the 20g came off the original blown engine in the talon

I will definitely do a compression test. I hope its just the oil cooler

You're going to have to flush everything anyway but I would also do a coolant pressure test on the system. In addition also pressurize the oil cooler by itself by removing the lines, capping one side off and a little shop air on the other.

Are you talking about like an external oil cooler that mounts next to the Intercooler ?

No. You don't have one of those. Only the 90 does. Stock 91 up have antifreeze/Oil cooler at the filter.
