Cam seal(s) on a 1998 Volvo V70 XC

[Joseph C]

Mine is leaking oil. Is that a big job?

Volvo community feels it is a can seal..

I believe that a special cam shaft alignment tool is needed to reinstall the cam cover. You should definitely check that before disassembling anything. You were not specific about the location of the leak but my 2005 XC 70 has a similar 5 cylinder engine. There is a small hose from the PCV system that goes into the top of the cam cover in the center of the engine. The hose gets very brittle from exposure to the heat from the engine and it cracks leaving oil on top of the head under the plastic cover plate. It is easy to check to see if that is the source of the oil. I have already had to replace mine twice. Good luck and stay dirty.

I know the exact hose you are talking about. It is right next to the oil fill hole. And, yes, I have random oil on top of the engine..

It gets plugged up with sludge bits. Should I feel confident in simply wiggling it loose, and maybe using a pipe cleaner or something?

I’ve used thicker viscosity to combat any lost oil while running, as a temporary fix. I love the 5-cyl 20-valve turbo. Has a nice exhaust note, too.

I read it could be a couple of different sources… The oil seems to be right behind the driver side tire. And last time I checked, a leak won’t fix itself without either “stuff in the oil,” thicker oil with seal conditioners, switching AWAY from a synthetic, or replacing the leaking part . .

Here are some more pics. The last one is the most relevant. Taken just now.

Ground was clean before I parked it.
