One size fits all (on the next page)?
LSM Racing one-tool valve lash tools configure to adjust all shaft and stud mount rocker systems on the market today. Buying a new valve lash adjusting wrench for each different rocker system is a thing of the past. Just snap on the appropriate standard 1/2 in. drive socket, insert the correct hex key, and you are good to go.Most modern ones have different sized hex heads as the adjustment screw. A standard flat screwdriver is used on 216/235/261 (see the tool in the photo at the link above). The tightening nut size can be matched by the size of the drive socket (not included with the tool).
I've seen the old
Protro version and that works quite well.
This one in Australia would also work.
