Just thinking this through. Would there be a downside with putting a slit in the rubber grommet, like we do for key punchings? I can see how it would save a lot of time during installation.

Ben. While I’ve never done it that way, I’ve heard it done like that successfully by many technicians. My only concern is when the screw or nut has to be adjusted for lost motion.

I tried it today and it went well. Much faster than disassembling the lifters. Had to adjust lost motion afterwards, no issues with the grommets.

Ben. My concern isn’t when the grommets are new and flexible. What will happen in 25-30 years when the rubber is hard. Will the slice in the grommet still hold when adjusting lost motion?

Hi Wim,
When the rubber gets hard, it'll be time to replace them again as they will start getting noisy and breaking apart.

The last job like this that I did, the metal fingers that the grommet slides into were rusted.  In addition, many of the old grommets were so hard they disintegrated on removal with bits and pieces of the old grommet left sticking to the fingers.  I felt a lot better about the job by cleaning out all of that mess.
