Any machinists set valves on an DOHC motor?
 
I have been looking at my solid lash adjusters. And there is no room to get a feeler gauge inbetween the valve and the rocker (the rocker has a channel that rides on the valve)

I can measure the distance between the cam and the roller on the rocker.

The only way I can adjust them is to do it one cylinder at a time (2 intakes or 2 exhausts)
Then pull the cam and adjusters lock the locknuts, then recheck them. Then move on to another pair of valves
Any ideas on an easier way to do it?

Artie split the feeler to desired width.

Art---see if ya got any motorcycle mechs around they have the same situation with the Jap bikes take a rocker over and see if one of their feelers will fit in your rocker--also ya using the PT cruiser NA rockers ??? they will take a lot more/higher rpm than a stock one---look at a set of DRAPER feeler gauges usually kinda long narrow tips lotsa bike mechs use this type

Thanks I'll do that.
Using 2.7 rockers they are a bit better than the PTs

Art---what you are looking for is TAPERED feeler gauges---they have a narrow point you stick in the rocker then get wider as they go back towards where ya hold em

I just bought a set of Honda motorcycle gauges on Ebay I might have to trim them but they look like what I might be able to use.

Ralph beat me to it. I also have one, but it was a gift from my wife. Would not part with mine either. Can you somehow use a dial indicator? That was my first thought, then scrolled down (iPhone) and saw Ralph's post. A bright guy like yourself can come up with a way to use a dial indicator. Think you'll like it.
