Hi, I have a RRS2010 TDV6 3.0 litre. I have noticed that I have engine oil in mycoolant overflow bottle but no water in the oil or overpressure inthe coolant system and since changing my oil filer an oil leak fromthe top of the engine running down the right side. I have rechargedthe filter and seal but still leaks slightly. I am leaning towardsthe oil filter housing, oil cooler. My questions are is it mostlikely that the oil filter housing / cooler is the problem and canthe oil cooler housing be overhauled with new seals and gasket as I’min Australia and postage from the UK is more that the second handunit. Has anyone had success in cleaning out the oil from system andcoolant bottle as it was replaced last year as the float sunk and Idon’t want to replace it again. I am a retired Toyota car mechanic.Thanks for any feedback.
