I've never seen one of these. Anybody know how they work?

From the looks of it, you would put the tool on the valve adjustment nut and then on top there's a built in screwdriver that you turn to adjust the valve. Pretty much it replaces a wrench and a screwdriver.

sj914 is correct.
It should work OK on Type 2 + 4's with the engine installed, might not be enough room to use it on a 914.
Most likely it's still in "excellent condition" because a wrench and screwdriver work just as well.

Here is a pic of a tool that I bought +15 years ago. Kinda neat not like you said, can't be used while in the car.

The knob has a srcewdriver tip on it and is spring loaded. The round piece has a hex cut into the end for the lock nut on the rocker arm.

Snap-on also makes a similar tool

Looks like you would have to take the motor out everytime you adjusted the valves. That is the hard way..

Its worthless.... just use the wrench and screwdriver!

I use chromoly pushrods so i don't need a feeler gage... just zero lash and loose enough to spin the pushrod! easy as pie

What!!.....What!!......Wait a minute. No feeler gauge? Zero valve lash? WTF!!
I haven't heard of this before. How do I do this? We talkin Megabuck push rods or what? Sure sound like an easy way to adjust the valves.

nice tease jake. brad mentioned running our engines at 0 lash some time ago to "wake them up". while thumbing through the lash manual i noticed the dif in valve adj specs for the different displacement engines. i'm still unsure as to why.

I thought 0 lash was the Hydraulic valve initial setting? and the majority of 914 push rods are chrome moly? except for Hydraulic(steel)?

Cr-mo pushrods are after-market, stock Type1 & 4 pushrods are aluminium, except hydro's they are steel.

I've been running 0 lash on Cr-mo pushrods on the hi-po type 1's since the early 90's. I still run .006 on stock engines.

I've never bothered with that tool.

just adjusted mine today to .004 all around.
got some more pull out of it, plus it runs smoother now.

Cro-moly doesnt expand like aluminium does when hot. I run my valves at .004 also.
