Just found these listings on eBay for tool sets for the 996 3.4 and 3.6 engines. One of the best prices I have seen for these tools.

Here is the one for the 3.4 engine.

Seems to have two of the cam hold down tools for removing the cam cover. two tools for holding the cam in place after the cover is removed, OEM style cam allocation tool, TDC locking pin and what looks like the tools for installing the wrist pins when rebuilding the engine/installing the 1-3 pistons. At $599 (with another 5% off before May 31st) it is the lowest price I have seen for these tools, particularly when it includes the wrist pin tools.

Here is the one for the 3.6 (VarioCamPlus) engine.

In this case it is only the cam allocation tools and a TDC locking pin. But only $155. You would still need the two sets of cam hold down tools.

Just thought I would post this for others doing work on their engines. I have a diagram and have made one of these tools, but the set for the 3.4 engine would have been very helpful when I had my cams out.
