Thank you for the write up! Worked out just like in your description for my '98 V70XC, making for a very easy job. I appreciate the help.

INSTALLATION TRICK: Hit the PVC bins at your local big box hardware store and get a pvc cap that's inch and a quarter (1 1/4")
A sleeve will do. You just want a round cylinder to evenly press the new lubed seal into its seat. It goes in a ways before seating. The pvc works perfectly for this. (If you do the intake seals, I think those are inch and a half. Take your seals with you to the store and just find the pvc fitting that is closest to the diameter of the seal without going over.

These were a bunch of great tips except I disagree with the ones I put in bold.

A perfectly installed cam seal will sit flush with the outer head surface, not all the way in. Don't push them in too far.

So you actually want a piece of pipe slightly slightly larger than the diameter of the seal, but thick-walled enough to overlap with the seal surface at the same time. This way the pipe will stop pushing the seal when the pipe contacts the outer head surface, and the seal will be flush like it is supposed to be.

I just finished replacing my rear cam seal. I accidentally followed the DIY for the non-turbo version! But it got me through it enough I was able to figure out the rest.

The one part that threw me was the lower bolt/screw on the cover was also holding a tubing bracket. Those tubes don't like to move up and out of the way easily!

Ok, so everything is back together, car starts up and runs, there don't appear to be any leaks from the area however.... I'm a bit concerned after reading everyones comments as to how far back to push the new seal. When I was following the DIY (for the non turbo) it said put the seal flush with the bevel... so I did, but from reading this thread seems like that might be too far. I've attached a pic of the area (circled in yellow) that I considered "the bevel" and thus pushed the seal in to this point.

Am I correct, or did I put it in too far?

Thanks,
Tim

No the rear's seat much farther back then the front seals. You will be fine.

Hi
I'm about to do this on my 98xc70 tomorrow on both rear seals. Just wandering, exactly what type of grease should I use? I was browsing at advanced auto earlier today and didn't find anything for seals but lots of gasket sealants and brake lubricants.
One of the workers actually tried to sell me a gasket sealant and dressing.
Can someone recommend me a good product to use?
thanks

Also I haven't seen a mention of how much to tighten the intake n exhaust rear cam bolts. Is there a specific torque?

I did not use any sealant.
And I do not believe there is any for this job. The seal is the sealant.

Tight.

But no, I do not know if there is a specific torque value on this, I am sure there is somewhere, but as long as its as tight as you can go without stripping it, it should be good. Usually these bolts are not very tight to begin with.

Re: REAR Cam Seal PN 9443310 ($18 at Volvo dealer).

Is it the consensus that Volvo OEM brand is the way to go?
From my research, Reinz or Elring ($3-4) seals do not last that long.

Just wet the seals (where it meets the housing) with some engine oil before install.
