URGENT HELP! OIL IN COOLANT HEADER RESERVOIR

Dear Forum

I have a fleet of Defender Puma Tdci 2012 2.2 litre vehicles. One has just arrived in the workshop with a report of the temperature gauge not working. On inspection there was A LOT of oil in the coolant reservoir and there was minimum oil level when inspecting the oil dipstick.

There seems to be oil spread throughout the coolant system when we checked the coolant pipes. Has anyone experienced this before?? The cylinder head gasket seems to be intact. It was suggested we check the oil cooler for a crack which would allow the oil to mix with the water.

Any help or suggestions would be really appreciated.

Oil cooler. Oil system runs at higher pressure than coolant system, thus oil contamination of coolant system NOT vica versa.

Oil temperature higher than coolant thus temperature gauge shows higher temperature as it is reading oil not coolant temperature. LANDYWATCH

Truck dealers use liquid washing cleaner like Persil or liquid Fairy in water. For a Defender i would use 250ml three times or untill the water is clean then flush out and add anti-freeze. 2008 RS4 gone, 123d M Sport, and a Puma 90 XS..

I have used fairy, persil washing LIQUID, (not powder) to clean water system and it works well. Just keep doing it until clear.

I'm talking about washing liquid for clothes, just to be clear not the stuff for plates etc.
