I am new to this forum and also new to Volvo's. I have just purchased a S80 T6 and absolutely love it. One glitch is I have an oil leak, it seems to be from the upper rear of the engine at the transmission end of the motor. I have checked around the valve cover and it is dry but there is oil over the top of the gearbox, down the rear of the block and on the exhaust manifold above one of the turbos. I found a couple of vacuum hoses that had collapsed from age and heat which I have replaced.Just after advice before I start pulling off heat sheilds to try and see whats going on...many thanks
