Oil in coolant tank
Discussion
Hi Guys,
I have recently had my head gasket done on my Range Rover Sport 4.2, 2006. I also had my oil cooler replaced at the same time.
After the job was done I paid & drove my vehicle for about 2,000 miles.
At first the vehicle drove fine but then after a few weeks I noticed a severe lack of power. I also noticed there was oil in the coolant tank that was not mixing with the coolant. Just to clarify, there was NO creamy sludge. There was just oil sitting on top of the coolant in the reservoir.
I took it back to garage & they scanned the vehicle. They found one of my coils had failed so they replaced this one & the vehicle has driven perfectly since. I mentioned the oil in the reservoir & they said it could be residue. They drained the system & gave me the vehicle back.
The oil is still present so I just want some advise as to what could be the problem.
I have heard a common issue is that the oil cooler pipes can be fitted the wrong way round. I am not to sure how an oil cooler works & how to get the data to check these pipes. How would I know if this is the case & how do I check if these pipes are fitted correctly. The oil cooler has very easy access as its located at the bottom of the engine. Does this vehicle have 2 oil coolers? I can see a sort of cooler either side of the super charger but they have radiators so I do not believe these have coolant running through them (If that's how the cooler works).
I have also heard the block could be cracked ................... before I ask the garage to investigate into the issue any further, I thought I would get as much advise as possible as I have already forked out £1000's.
Thanks in advance for any help/info/guidance anyone can offer.

Probably residue left in the system after the previous failure.
Get rid of the oil, even if you have to overfill and float it off the top, get your level to where it should be and monitor.

put a dishwasher tablet in the coolant tank and drive for a couple of hours, then drain the resultant mess out.
water by itself isnt much good for shifting oil, but dishwasher tablets are especially good at it. after its clean you will have a much eaier time monitoring if it gets contaminated again.
