So far, I've been removing the lash adjuster from the rocker arm, screwing a thin locknut onto it and then doing the obvious, locknutting it in place.

Since I got the motor running 3 months ago, I'm up to 4 with that treatment.

You can squish the arms in a vice to make things a little tighter.....or if the reason they are backing off is a lot of meat milled off the head or deck....you can use shorter pushrods.

Mine are just loose from age and many movements, apparently. I don't have a vice, and taking off the rocker arm to do that seems like a pain.

Years ago, my poly 318 had the same problem, but those were cast rockers, no squeezing them was possible. I ended up using a washer under the hex on top and it just happened to make it tight at the proper clearance.

I've been quoted $50 + shipping for a rebuilt rocker arm assembly, but how are they "rebuilt"?

3/8" fine tread jam nuts is another way.

the adjuster set from isky for a 426 hemi work... they have a lock nut and allen head...

they are a little tall with higher lift and hit the baffle but thats an easy fix...

BTW, how do you live w/o a vise? Since age 5, I think I was without one for a couple of months around age 25, and I almost went mad...

I used to be a mechanic... worked in a diesel shop for 13 years. Now, I have no shop, I lost all my tools ( 3000 worth of Snap hand tools alone) to theft, I don't even have a carport to work under.

So, sorry, no vice. It's a pain, but I rent and have no choice.

Wow, that is terrible.

When I had just a carport in a rental apt in SoCal (6 yrs), I got a hold of an old army footlocker and bolted a Sears vise to it, then filled it with 250 lbs of rear axle and engine parts and locked it. Nobody gonna walk off with that.

my car came with the jam nuts already installed, being a mopar newb, i thought they were suppose to be there. the vw's have them, those germans sure know how to build a motor ;-) theres never a adjuster problem, unless you buy cheap unhardened adjusters from EMPI and they get eaten away in less then 5 minutes
