Oil in coolant
Hi there.
Unfortenately my Disco 3 2005 HSE TDV6 2,7l have a problem.
Some week ago saw some oil drops on coolant tank when filed it up a bit. Yesterday change engine oil and checked coolant as well. There are a lot of oil. Seems that can be one of head gaskets. By the way, coolant loosing also, slowly but loosing, aprox 2-3 liters per last 8 months. Coolan is not in the oil.
Any ideas what else or just head gaskets.
Thanks in advance.

On a lot of Ford engines they have an oil cooler that uses the water to cool it which often fail not sure if the disco has one though but possibly has.

Search on forum, I believe the Transmission oil cooler fails and water gets in the transmission killing the torque converter!Series 1 V8
Series 2 Hibrid V8
Discovery 3 HSE V8

Or an EGR cooler!It can when others can't,
It will when others won't,
It goes where others don't.

The oil water cooler is under the oil filter. Or near it

Same issue here - I suspect EGR cooler or oil cooler. Oil looks fine - no signs of milkiness although have not done a glycol test.
Mine has lost about 1L of coolant in 40,000km so not a big worry, but want to fix this.2008 RRS TDV6 - Chawton White/Black/Lined Oak - 20's, h/k, sunroof - 350K KM.

There it is, I took this picture when Mick Flack was replacing mine (Black arrow pointing to it but hard to see )The happiest of people don't necessarily have the best of everything;
