  View original topic: late t4 rocker arm washers

anyone know where to get new rocker arm washers for T4 motors? Don't need a whole kit - just trying to locate new unworn spacer washers. Right now I am running OG hydraulic / GE style solid spacers but all my spacers are worn thin and I'd like to add some insurance against failure in this area. I know about the valve shims being substituted but would like something more like the original.

the GD & prior with springs took 025-109-435
the GE motors with solid spacers took 021-109-437

I would measure the stack you are running and check out mcmaster for a shoe in. If you are feeling frisky go w/ a bronze or sinterd metal to lower friction here while running a tighter gap to control the rocker loads. I may go this route on my motor with slightly more lift on the cam, and if I have no failure use it on my future big bus motor which will use much more lift.
