2001 S40 Timing Belt and Cam Seals

rhlee222 · Post by **rhlee222** » 13 Oct 2013, 18:22

Hi everyone,
I know this car needs a timing belt and plan to replace it next weekend. I took the upper cover off and noticed oil on the belt and also on the cover. I didn't have time to look any further. I'm assuming the cam seals are bad but am not positive. I would like to have everything in hand that I could possibly need to fix this. I need to get this belt replaced ASAP. I don't trust it to last much longer.
Besides the cam seals, are there any other seals that could be causing this leak? Driveshaft maybe? Also, What special tools are needed to accomplish this. Is the water pump on this car driven by the timing belt? Any additional info. Is greatly appreciated. I want to gather up everything I may possibly need.
Thanks so much,
Rick

This may be of help.
Crankshaft seal may be showing signs of leaking also? Worth a check.
Many use a camshaft locking tool to avoid upsetting the timing but others do not bother and simply exercise max' caution.
Many posts relating to timing belt replacements on all the forums well worth browsing through first.

Thanks for the info. Where can I get a camshaft locking tool?

Plenty on ebay and amazon but you can even make one yourself with basic materials.
Will hunt about for an older post for a DIY version of tool and add shortly for you.
As said earlier , many posts for S40/V40 or other models with same basic procedures on the forums worth your while reading before jumping in.

Thanks for all the help so far. I'm really starting to stress over this project for the following reasons.
First, this car needs the timing belt badly. This is my sons daily driver and I know if I don't do this soon it will break. Second, this car needs a PCV service. I'm afraid that if I do the seals, but not the PCV I will blow out the seals again.
I'm going to try to do all of this this weekend if possible, If I can get all the parts in time. PVC, then seals, and finally timing belt, tensioner, etc.
How would you approach this? the timing belt looks awful.

You need to do all of this work now and in one concurrent procedure.
With the inlet manifold removed you can do the PCV easily and quickly.
Naturally the next step would be your seals along with waterpump, tensioner etc.
Fitting the new timing belt last is obviously the reverse order of stripping down anyway.
If the belt looks dangerously ready to snap you must start ASAP and avoid running the motor as a failure through delay will severely damage the valves, pistons, head etc.
