<VV> To Much Oil Flow to Rockers

[R]

Just my opinion, but since he says he is running a high volume pump, I think he would be better off leaving it as-is instead of risking new lifters on a used cam.

As soon as I can get two (2) replacements from Clark's (when they reopen) I'll be replacing both #1 cylinder lifters. I'll also be inspecting all above-the-head valvetrain components for #s 1,3,and cylinders. Thanks again, and I'll keep you posted.

Lifter innards have a piddle valve  or small grooved disk to allow oil to flow from lifter body to pushrod. May be stuck open, missing, etc.  There may be another cause and that is your pushrods may have larger end holes than others. Once pushrod itself is filled with oil, the amount of oil is limited that is discharged. As others will tell you, I may be fullash*t. I would examine pushrods and if ok, certainly change htose lifters.

Most replacement lifters today don't supply enough oil to the rockers. Long story short it's much easier to adjust the valves cold not running. No mess no clean up. Shop manual shows how.Paul Fox

Anyone ever seen this condition? All I know is the lifters ultimately control the amount of oil to the rockers.
> More Info: May not be both, just looks like it. For adjusting while running, I use valve covers with holes cut out right over the adjustment nut (rather than half-covers). Most of the oil is sloshing out the rear-most hole, while some, but much less, is coming out the more-forward, #1 cylinder rocker area. To be sure, thinking  I'll change both lifters... not a big job.
