Camshaft Locking Tools (for an earlier 5 chain engine)
All you need to fabricate your own cam locks is a bit of flat iron and a grinder. I recommend you cut the iron to the rough outside dimensions first. Then, hold the metal into place and mark the notch to make it fit into the end of the cam. Once it's notched and fitting correctly, mark and drill the hole as your last step. Below are approximate dimensions. This tool should be the same for all early 5 chain engines on both the 986 and 911. Again, I recommend you check the measurements by holding the cam lock in place, marking the location, and grinding down as necessary. For later 3 chain engines, the process is similar, the tool will need to be double sided to lock both camshafts in place.
