Which engine.

 

Hi Andy,

2.0 sri Cdti ecoflex. 158

 

I suppose you would have to either replace the cooler or see if there are any gaskets available or try and bypass it by joining the two coolant hoses and see if you still get oil in the header tank.

 

Great advice. What do you think it sounds like? Il bypass it as you say and then see.

Do a coolant flush to get rid of all oil on the system first and take it from there.

Thanks Andy

Take the oil filler cap off and have a look to see if there is any cream/mayo looking sludge on the underneath, if so then it could be head gasket, if that's clear then do look at the cooler replacement, might be worth changing the header tank too as it will be contaminated now, cheap enough to buy on ebay, let's hope that it's just the cooler gaskets---Dave

Hi Dave,

Yes mo cream or mayo on the filler car, oil in the engine looks ok.

Will defo replace header tank as its filthy haha.

Fingers crossed indeed and many thanks

No problem, I just bought a new header tank from ebay the one with the sensor and it was only £20 - - -

 

Hi Dave, header tank and oil cooler ordered.

Did you have oil in the header tank on yours too? Was it the oil cooler causing it?

 

No mine was fine it's just that I needed a header tank cap as they tend to crack, got the cap off a mate of mine and just decided to change the header tank, easy job-just drop enough coolant until the tank is empty then just remove the hoses and the electrical connector and lift the tank upwards, no need to remove anything else and just replace everything with the new tank in place - - - Dave
