Guy's I am currently working on the valve timing of my monty where I have timed the Exhaust cam to the correct position but I now need to adjust the inlet cam which is 13? out on the factory timing mark. I am using cam lobe centers as my reference point which means that once the crank is in the correct position I need to disconnect the camchain and turn the inlet cam to the valve full open position ( Lobe Center ) and lock the cam in this position while I unbolt and adjust the cam sprocket which has extra holes machined into it, which brings me to the point of this post:- I need a camshaft locking tool that can lock the cam without using the sprocket. Has anyone done this and made up a locking tool or modified an existing tool to fit.
Thanks Glenn
 
Hi Glenn,

The factory never issued such a tool.  There are bores in one end of the shafts, these were used for manufacturing purposes. 

Elongated holes in the cam/chain wheel mounting flange is the accepted method of fine-tuning the cams on Lav engines. :D

most modern car engines have cam locking tools for belt changing purposes, some lock the pulley, others lock onto an actual lobe. Alfa are a good example, esp. the quad-cam V6.
Ive never done it but there is no reason why a tool could not be milled out of a block of aluminium that fitted onto the studs of an outer cam bearing cap that then fitted over the ajacant lobe & locked it into position.....
2 pairs of hands is another method ive used over the years, esp. when timing the inlet cam & joining the cam chain at the same time!  ???
