Title: odd valve adjusting
Post by: fryedaddy on February 22, 2025, 01:07:05 PM
i adjust my valves one at a time turning the crank 1/4 turn at a time and watching for opening and closing method. but a few years ago i brought up adjusting the valves on a fe while the engine is running and i pretty much got laughed at by a few members but thats ok. i was watching old nascar footage from the early 60s today and what do i see,a mechanic adjusting the valves on his fe galaxie while it is running.i thought i remembered this method from 50 years ago. but i still would not try it myself.

I've done it with a hydraulic cam.  I have a valve cover with the top half carved out so that only the pushrod side of the valvetrain shows.  This is so that I don't create an oil flood.  If you have the factory adjuster, it's not very hard as you are dealing only with the adjuster nut.  I have Crane iron rockers where I had to deal with the adjusting screw and the lock nut.  It's very bouncy for sure.  For a solid cam, I'd still want to do it with the engine off.

I was a mechanic, between '62 & '70 and it was the most common (at least in my area of SO Cal) to adjust valves. Messy yes and very hard on feeler gauges. I still have my set of feeler gauges that I used for that.

You also used a feeler gauge to find a loose rocker arm or bad lifter on hyd lifters.

That's the way I was taught to do it in the 60's.
Used that method all though my mechanic career of over 50 year's.
I did like GerryP though and used the cut off valve covers after a couple of time's cleaning oil off of everything.
That ten cent a quart oil got a little expensive after a while.

It works pretty well on trucks, tractors and cars with very mild cams. I learned doing old REOs and International sixes where you could idle them down to around 300 RPM and they wouldn't toss oil around

I did it that way on a 406 back in the 60's when I was a teenager!

My old man always adjusted valves while it was running so that's how I did it. This was back in the early 60's so most of them were Yblocks. Sure could get some of those to run pretty sweet.

Again, works pretty good with smaller cams. trying to keep a wrench on an adjuster with a high lift cam and higher RPM is a little more difficult

just reminising and remembering from when i was a young man. i like the quarter turn at a time while watching for opening and closing method myself.
