Hello ,

I have a 2006 S60 2.5 T AWD that I really enjoy driving ... about 260000 kms.Not nearly as quick as my wonderful 850 ... (deer ending) but really solid in many ways. I have an oil leak that has become an annoyance as it is staining my parking spot (board there now) and I am having trouble figuring this out. It started with a code indicating that one of the solenoids was getting stuck and so I replaced both (intake and exhaust) at the same time. Bona fide parts from Rock Auto. I purchased new gaskets as well and replaced them also.
I now get oil collecting in the little notches and gullys on top of the engine under the covers and eventually they drip down. It's not a big leak but an annoyance leak and I'm concerned that as I'm driving it is slowly getting air blown around inside the compartment possibly affecting things like my belts etc.
So I cleaned it all up and ran the car for a short while and it appeared that oil was slowly coming out of the bottom of the exhaust solenoid. I cleaned it all up again, and put a second (new gasket on which seemed to slow it but the leak appeared again. Yesterday I did the job one more time and used a silicone sealer... on BOTH solenoids... the leak has slowed but is still there.
Is it possible to have a leaky solenoid? Has anyone ever had this issue? Is this created by some other issue like too much pressure in the PCV system or something like that? Perhaps just get another solenoid?
Any suggestions would be greatly appreciated. And Klaus C... I hope that you are well that your Volvos are purring. Thanks to anyone replying in advance.
