Noticed an oil leak under pan after an extended drive. When I had oil changed, mechanic said it appeared to be the valve cover gasket. It looks like there are a lot of plastic covers and wiring to remove in order to access the covers. Since the covers would be coming off, shouldn't the valves themselves be adjusted at that time?
Can a do-it-yourself guy handle replacing valve cover gaskets on this vehicle? on 2004 Volvo XC70

This engine doesn't have a valve cover gasket or adjustable valves. It has a camshaft cover that is sealed with a liquid gasket, and they rarely leak. Did you have this looked at by an experienced Volvo technician?

This is good information. I wasn't aware that this Volvo engine didn't have a valve cover gasket or adjustable valves. Another mechanic speculated that it could be the turbo. Enough guessing, I will definitely have an experienced Volvo tech diagnose it. Thanks for the info.

Good idea. There's a good chance this is just the turbo return line seal. Very common. http://repairpal.com/oil-leak-from-turbo-return-pipe-seal-557 But there are other possibilities as well. Make sure they replace the oil filler cap seal and clean any oil that has settled on top of the engine if it was leaking.
