Something like this?



Are shims reusable? Do all prechambers get shimmed the same in the engine? If I can’t get to the car a while, does it make sense to buy a selection so I can hit the ground running when the time comes?

I assume the shims are there so the glow plug hole lines up on the prechamber?

Were there differences in prechambers across engine years? Or are all 601/602/603 prechambers the same 601 part number?

Thanks!!
