Thanks for the advice.

My Boxster has an undersize underdrive pulley without a TDC hole or marking. Unfortunately I don't have the original so I'll have to lock the back of the engine.

I've found a few threads where others had this problem, I plan to rotate the engine until all 4 cams have the slots "vertical" with the smaller half moon facing away from the crank, fit the cam locks (I have 2) then lock the fly wheel side of the engine.

Any other suggestions as to how to find TDC with my configuration would be welcome.
