I am considering replacing the spider hose assemblies/PCV valves on my 2001 S4 and my girlfriends early 2000 S4. I am hoping this may prevent future oil leaks due to excessive positive crankcase pressure.

Both cars have about 125K on them. Both have had oil leaks from the valve cover and cam tensioner gaskets.

Do I need to replace the whole assemblies or just the valves themselves and clean out the various hoses?

Does anyone have the current part numbers for the assemblies. I have seen different part numbers floating around. I need the numbers for the 2000 and the 2001.

Does Audi now refer to the PCV valve as a Suction Pump? I have got a part number 078-133-701-AD for the 2001. It is called a Suction Pump?

Also any suggestions for a good place to get the parts would be great.

Thanks in advance!

The spider hose and valves come as one part, pressure limiting valve and check valve going into the intake manifold included. I picked up the updated model at the dealer for about $120. The list was more but they cut a few bucks off when I commented about it being available from other places online for less. The new model has heat shielding and an updated pressure limiting valve. Here's a pic someone else posted a while back. I do not believe Audi is calling it a suction pump now.

I have the part number at home and will post it later if no one else does. There are two versions for the B5, and they can tell which you need by your VIN.

Also do you know where the VIN number split occurs between the two?

Any online sources for the part at a good price?

Thanks for the responses!
