I did see that during my search. Definitely won't be buying for that price. Which leaves only one other option...take out the whole camshaft assembly to access the shims. Reading the service manual, I was wondering if all the steps are necessary.
1. Remove fixing bolt for camshaft drive gear pulley using the J-4341 universal holder.
2. Remove twenty fixing bolts from inlet and exhaust camshaft bracket on one side bank, then camshaft brackets.
3. Remove camshaft assembly.
4. Remove three fixing bolts from camshaft drive gear retainer, then camshaft drive gear assembly.
I would rather leave the drive gear pulley alone if I can (step 1 and 4)...I know timing is going to be an issue. Is it enough to just remove the brackets and pull the cams out? (step 2 and 3)
