Y-Block Question

Quick question about Y blocks.

The thunderbird has shaft mounted rockers on it and is making a lifter tick, upon closer investigation the rocker arm on the foremost driver's side cylinder has a significant of lateral play, and appears to be the culprit.




(not my photo, but it's the leftmost rocker held back by that thrust spring/washer)

The other rockers appear fine. However the shop manual is of little help, and offers no course of adjustment. I'm assuming the washer spring has lost it's temper, but I'm not sure and wanted to ask more experienced hands what needs to be done.

Thanks.

I can't help you Steve but you might want to ask that same question on the Yblock forum. A lot of experts there.

I doubt that will be an issue , more likely the valve clearance needs to be checked .
