Wayne, thanks for the write up and pics!! Excellent work. Your use of set screws once the IMS cover is off to hold the shaft in place confuses me just a little. If I lock the engine at TDC and put in the cam locks what if the sprocket isn't lined up with the holes? Was this done in lieu of using cam locks? once the locks are in there is no aligning the sprocket for the set screws, what's the best way to keep the shaft in place?

One question at a time please. If the holes do not line up the chain is stretched or has jumped time. Try moving the camshaft and see if you can line up the holes. Using the cam locks is the best way to secure the camshaft gears
