    Hello everyone..I got a 07 Volvo 670 with Cummins ISX 13 speed eaton fuller..it got 1.160.000 miles on it..last night I found out there is oil leak where engine meets transmission..when i left it on idle it drips but not so much when I turn off the engine it stops..I put a cardboard underneath and the oil is black..I assume it's not transmission fluid..my question is if it's an oil leak where is it coming from and what causes that?
    Thanks

    Sounds like a rear crankshaft seal. Pull the clutch inspection cover off the bottom of the transmission bell housing and look up inside with a light. If there is oil slung around all over inside the housing, chances are its a blown rear crank seal. If there's no oil in there, check up above, on the back of the head and valve cover for a possible leak.

    If you're going to do the Rear Main Seal, you might as well replace the Clutch since you have to pull the Transmission out anyways, and Volvo's are known for the Transmission Mounts needing to be replaced, so you might as well change those out while the Transmission is out too.

    You're probably looking at anywhere from $1.500 to $2100, depending on type and costs of parts and what a Shop charges to R&R.
