2003 S40 1.9t Camshaft Seal Part #'s

Livens · Post by **Livens** » 24 Dec 2013, 20:18

Hello all,

While looking over my new Volvo I found a serious issue. While running and with the smaller top TB cover off oil is being slung everywhere, both cam gears are covered in oil. So I either have a leaking cam seal(s) or that little plunger thingy on the CVVT hub is leaking. Or both. I wont know until I have time to pull the rest of the TB cover and do a thorough inspection.

Either way I will most likely be replacing all 4 of the cam seals. But after looking at many online parts sites and reading several posts about the seals I cannot verify the part numbers I need. I also read that on the front (TB) side the intake and exhaust both use the same seal, and both rear seals are the same. SKF 11809 for the rears, SKF 17806 for the fronts.

Do I have this right? Can someone help me so I have the correct seals before getting started on this?

Also there are a few tutorials showing how to replace the front seals, but nothing super detailed. From what I have read the front intake side is a piece of cake but the front exhaust side with its CVVT hub is a PITA! The rear seals are both pretty basic. It would help if someone could post some links to some better tutorials covering front cam seal replacement.

Wish me luck and Thanks,

Jeremy

Did some more research and found this:

Front Camshaft Seals: Volvo# 9458309, interchange to SKF 20014
Rear Camshaft Seals: Volvo# 9443310, interchange to SKF 11809

I will wait and see if anyone has better info before buying. I need to fab a camshaft locking tool before starting in on this anyway.

Merry Christmas everyone!

Jeremy

Finally had a chance to pull the TB cover off and take a good look at the leak. It's the VVT Gear/Hub plunger that is leaking. Oil was sitting in the depression the plunger sits in. I wiped all of the oil out of it and ran the engine for a minute, it filled that depression back up. Then cleaned again and disconnected the VVT Solenoid, ran the engine again and no oil this time. I think that test pretty much settles it.

So the seals, and my PCV system, may be good. But since I have to take the VVT Hub off anyway the seals will be done too. And also a good inspection of my PCV system.

I finally thought to just call up a dealership and ask the parts dept... Here are the correct camshaft Volvo PN's:

Front Cam Seal, Intake side = 9440651
Interchanges to an SKF 17918

Front Cam Seal, Exhaust side = 9458309
Interchanges to an SKF 20014

Rear Cam Seal, Intake and Exhaust = 9443310
Interchanges to an SKF 11809

I have the same car (V40) and the same issue. Oil dripping out from the timing belt enclosure and everything is covered. Thanks for posting the part numbers. Can you post some pics of the replacement along with some tips?

BTW: How many miles are on your car? Mine has 248k.

My S40 only has 116k on it. I don't think any of the seals are actually leaking, its the VVT gear that has the leak. But since I have to pull the gear off anyway I might as well replace the seals while I am at it. I am also changing the timing belt, idler, tensioner and water pump at the same time.

No problem on the pics, I will be documenting the whole thing start to finish.

Thanks. Looking forward to it...might be taking a vacation day soon to do the VVT gear and seals. Its leaking bad now

Is this the well you were talking about (the one filled with oil)?

Myo,

No, but I had oil there too. I found this pic on another forum that shows the plunger on the VVT gear better:

The plunger is all the way to the right of the image, under the outer gear.

And here is a pic of my VVT gear that shows where it is better. The gear on the left is the VVT, and you can just see the plunger peaking out from behind the AC hose. You might need to remove the upper timing belt cover to get a good look at yours. There is a 10mm bolt to the left of the engine side motor mount.

I just finished the job a couple of days ago, everything went well. Neither of my cam seals were leaking, but I changed them anyway. And let me tell you, this is a major undertaking. I had at least 12 full hours into it. But way better that paying someone else big $$$ to do it.

I took lots of pics of the process, and made good notes along the way, Ill try and work on the writeup this weekend.

Cleaned mine tonight. It looks like the crank seal is my culprit. Thanks for all your info!!
