(1999+ models are somewhat different)
There are a few DIYs for REAR Cam Seals but sometimes little tricks (i.e. ow to mark and how to remove seals) are not mentioned.
So I will write a quick DIY with all the tricks to make it painless
Here is a good DIY: REAR Cam Seals by “RobTheModd”:

REAR Cam Seals: Volvo Only?
http://volvospeed.com/vs_forum/topic/15 ... olvo-only/
I just installed the SKF Rear Cam seals using SKF 11809. In every respect, it looks identical to the Volvo seal.
I bought the SKF 11809 Seals from local SKF dealer (semi-truck parts dealer): $6.50/each = $13.00 total.
NAPA autoparts also sells this SKF 11809 seal for $9.50/each, make sure you ask specifically for this seal. Anything other brand, you will be a guinea pig. Local Volvo dealer wanted $33/each!!!
From reading forums, it appears that people who have leak probably have:
- clogged PCV
- ??? using Elring brand
- improper installation (pushing it in too deep)
One of the key things about seal: the seal must be a bit bigger than the bore. Let's say the engine bore O.D. = 47.00 mm, the SKF seal O.D. = 47.32 mm. You need that 0.32 mm difference to make it fit tight, otherwise it falls out.
For a long time, I am baffled by people in forum who swear by Vovo seals (which I sometimes do), but after I did my research, the Volvo seal is made by SKF, then I am not afraid to use SKF.
I will post a follow-up from time to time.
So far bone dry.
-------
TOOLS:
- Allen keys
- Torx keys
- 8-mm and 10-mm sockets
- 36-mm socket (the same socket used for Axle work): to drive seal in. This socket happens to be perfect because its O.D. = 47.50mm, which prevents the seal from being driven too far (read on…).
- Hammer
- Sheet metal screws
- White-out (or some touch up paint) to mark the parts for easier install!

PROCEDURE:
* Get a box to put all the loose parts inside to avoid loss/confusion.
1. Spend 5 minutes moving the Air Box, your life will be 1000x easier! Trust me with this! NOTE:
- MAF connector
- 2 vacuum hoses
- Large intake hose
- Hot air heater pipe
- Just make a note of all these things for easier installation.

2. Start with INTAKE Seal:
- Remove Distributor Cap: 3 bolts (8-mm socket).
- Remove rotor shield (do not forget this during install)
- Rotor is held by 3 hex bolts (3-mm Hex)
- NOTE: Mark the rotor plate (this is used to time the rotor for ignition) with paint at 12 o’clock position to make install painless! If you reverse this during install ---> no start!
- Remove the rotor plate (10-mm socket)
- Now you can see the oil leak trickling down the weep hole.
- NOTE: the factory seal sits about 1mm from the edge. This is important for install.
3. Next is a TRICK taught to me by pro mechanics:
- Use sheet metal screws to extract the seal.
- Study the new seal to get familiar: the OUTER Ring is steel coated with Nitrile Rubber (or something like it). The INNER Ring is pliable and has a tiny spring encircling the INNER Lip.
Virtually all engine seal has this design.
- You want to drive the screw right in the center of the steel part. This will avoid damage to the mating surfaces.
- You can use only 1 screw (I used 2 screws) and grab with a pair of pliers to pull the seal out.
- Trick: use a small nail and gently hammer the seal to create a hole first, then drive the screw in.

4. Next is picture of mating surfaces.
- Clean all around mating surfaces with a clean rag and your pinky finger; no screwdriver!!!
- Apply a thin smear of grease (or oil) to: OUTER Lip (where it mates with the bore) and INNER Lip (where it mates with the cam shaft).
- Now use the 36-mm socket: gently drive the seal in with the hammer. Go VERY VERY SLOW because if you drive the seal in too far ---> leak later (and you just destroy a brand-new seal)!
- Adjust the socket in such a way to drive the seal in equally and just 1mm from the edge of the bore.

5. Now move to EXHAUST Seal. Similar procedures:
- CPS (Cam Position Sensor) is mounted by 2 Torx bolts.
- Note the metal bracket.
- Again, mark the piece at 12 o’clock position to make install painless!
- You can see oil leak here trickling all the way down and may simulate RMS leak etc.
- Remove old seal with screws, install new seal.
- Make sure it is 1mm from the edge.

INSTALL NOTE:
- Pay attention to all the parts removed.
- Now it is a good time to de-grease this area. This way in the future if there is a leak, you know it is new and not from old stuff. I use “Purple Power” cleaner, followed by gentle water from 1-gallon container (no pressure washer!).
- Remember to connect the Air Box properly!
Congrats to a job well-done for only $13.00 using SKF Seals! Now it is beer time...
