1.5 or 1.6 roller rockers.

Wait wait wait. Why do those rockers look like they are guided? Meaning why does the rocker stick down below the valve? That isn't correct.

Also, if you need to move the rocker over, just file down the hold down. It ain't hard.

I just don't know why the rockers are guided.
Ain't that a kick in the pants? You never seen those afore? Yeah just let them slap around off the valve tip and guide themselves. The ones that showed up here actually contacted the retainer also. At least that doesn't appear to be a problem this time.
