T4 oil in coolant

[Racemag]

apart from the head gasket is there anyway that oil could get into the coolant?

[Bug_racer]

Oil cooler located just above the oil filter and if its an auto oil cooler on transmission

[Umai Naa!!]

Oil cooler/heat exchanger on the back of the block.

OK, thanks will look at it. How do they leak? do they crack?

[Umai Naa!!]

They corrode or break down internally, allowing the coolant and oil to blend.

I have no coolant in the oil, just oil in coolant

[Umai Naa!!]

WIll most likely be the cooler.

that would be a bit of welcome good luck. Is there an easy way to get to it?
