VarioCam Plus compression tool? (removal of camshafts in 02+)

[987_RDC]

I've seen quite a few posts detailing removal of camshafts in the 3.4L engine. There is a Porsche tool that appears to be a very long screw that compresses the VarioCam as part of the removal process. Is this the same tool needed on VarioCam Plus engines? I see the actuator is external on the 3.6L.

Also what is the diameter and thread pitch of the VarioCam tool? I had read 4mm and left handed threaded....but unconfirmed.

There is no need for the tool you speak of on the 3.6L or Vcam Plus engines.

The 3.6L has a completely different set of tools than the 3.4L. Primarily for the 3.6L procedure you just need to lock the cams down before loosening or tightening the cam assembly. There is a very precise procedure to follow however, which includes rotating engine/etc. If you don't follow that procedure exactly you will cause damage. You can purchase the pages from the WSM that discuss that procedure SPECIFIC to the vcam plus engine from the porsche piwis tech website.

The cam system is totally different between the 3.4L and 3.6L.

Logray is right, The long screw/bolt tool is specific to the cam advance mechanism on a VarioCam engine and is not required in a VarioCamPlus engine. However you will still need the exterior hold down tools prior to removing the cam covers (which hold the cams in place) and the other hold downs for when the covers are off.

Do you have the manual. It explains this and provides illustration. Let me know if you need this.

Perfect. Thanks for the replies. I couldn't confirm from the various other postings. I have a set of LN tools but was scratching my head on the differences between the variocam and plus tools.
