Do you really need a locking tool? Can't you just cable-tie them to a bit of metal or something?
It's just the miser in me doesn't like the idea of paying 70-odd quid for a tool i'll only use once.
Does the special tool let you hold the chain + gears in place while removing the cylinder head, or is it for cam removal only? I guess that might be more worthwhile.
To be honest its extremely hard to keep the chain tight without the tool. Any slack in the chain and it will come off the bottom crankshaft sprocket putting the timing out. You then have to remove the timing cover to set the timing again which leads to ££ in gaskets.
Easier and actually probably cheapaer with the tool.
p.s.
The tool bolts to top of the cylinder head, so the head can't be removed with it still attached.
