What to do when your lash adjuster is not working?

If one cam lobe is hanging over the lash adjuster a bit too much, you might not be able to pull the lifter out all of the way. If you end up in this situation, you can just drop the lifter back down into its socket in the head and crank the motor around (clockwise!) until you can pull it all the way out.

What’s the difference between lash adjuster and lifter?

NOTE: I use “lifter” and “lash adjuster” interchangeably. “Lash adjuster” is the correct term, but “lifter” is shorter to type. This took me about five hours total. I could have gone faster, but I’m not that kinda guy; I mess up less often when I take my time.

What’s the pivot point on a lash adjuster?

The rocker pivots on the lash adjuster. The cam spins on the roller that is built into the rocker, and this pushes the rocker down, which opens the valve. The lash adjuster is a telescoping pivot point. The excess play is supposed to be automatically compensated for by the automatic extension of the lash adjuster.

How to replace lash adjusters / lifters on dsmtuners?

Just roll up a big, thick wad of shop rag and put it between the intake cam and the pivot point of the prybar. This raises the fulcrum of the prybar so that the handle of the prybar doesn’t hit the throttle cable. Just wad up the rag so that it’s thick enough or use two rags…or three.

How does the cap on a lash adjuster work?

The cap on the lash adjuster keeps that end from moving laterally in any direction, and the two ridges on the other end keep it from moving toward the left or right sides of the car. I’m mentioning all of this, because it helps to know this when reinstalling the rocker.
