oil in coolant

[power=dsm]

k i just checked my coolant and their is oil inside, i'm also missing about 1/2 liter of oil. the car never blew smoke even while wot and 18 psi. Also my coolant level is down and i had to add some. The only leak i have on the car is my valve cover gasket. i can't check my compression cuz my ecu is fried. I did a leak down test about 1000 miles ago and and it was perfect. The reason i did a leakdown test was my rad broke while i was driving the car and heated up a little but never went hotter then the "mp" on temp.

unless someone is secretly pouring oil in your radiator then it is a cracked/warped head or head gasket. Quit driving your car immediately unless you want to pay for a new engine.

yeah you can confirm this by checking oil for coolant too.

i got my ecu back today and i did a compression test and got 155 on all 4. My car never smokes, and i'm losing coolant and their is oil in my coolant. whats going on here. My turbo has 500 km on it

there is no cooant in the oil, only oil in the coolant!!!!!

i had the same problem and it was my turbo, the stock 2g turbo was creating the problem, once i changed to an oil cooled t 60-1 i havent had the problem. but now i have the problem of the car driving fine at low rpm and hi rpm but lags at 4000 rpm to 4500 rpm, feels like the car is pulling back, cant figure this one out.

you are losing oil and coolant. So you are either leaking oil and coolant(possible) or burning them(probable). Since the oil and coolant are being mixed, and they are both running low i would think they are leaving the motor from the same place.

i would check out the block. there might be some waterjacket damage of some sort. its all guessing until you actually take a look. with the symptoms you stated i wouldnt drive the car anymore.

if the water jackect's were damaged, wouldn't i burn coolant??

how can i check my oil cooler to see if it's damaged?

 

[projctWraith]

My bad, I forgot that any coolant that could be getting into your oil will evaporate while the car is running; The water part will anyway.

How do i check my oil cooler to see if it's ok ot not

 

[projctWraith]

I don't see an oil cooler on your mod list. Do you have one installed? As far as I know n/t cars don't have one.

my car is an nt with a 4g63t in it!

Oh, then your oil cooler cools the oil with water. You could always install a pressure gauge right after the cooler in the return end. If your up to it, you can remove the oil cooler and route the oil back into the engine untill you can replace it. Limit driving it untill you get it fixed and no boost .

I've seen this before. Check your spark plugs too, for oil. You maybe have a leak in one of your cylinders. I've seen it cost about 3000.00 for a new head installed from a dealership. Hopefully, it's just the head gasket. I would check it out before it gets worst. Some signs I saw were very hard starting and oil on spark plugs. Good luck!
