Spring/Keeper interference with Rocker

The rockers on these LA engines are oiled from the shafts, which get oiled through the block. (Magnums oil through the lifters and pushrods, but not LA's.) But it sure looks like plen-tee of oil.

Gotcha - I assumed the oiling from the shafts simply kept the ID of the rockers OD of the shafts lubed, and I thought the pushrods oiled up to the top end also - Thanks for the lesson. I figured the lifters simply 'squirted' oil up the push rods to the rockers for additional oiling. Again, thanks for the clarification.

If you are pushing on all the rockers to try to find a soft lifter, or other loose valvetrain part, you have to tun the engine for a few minutes to get oil in the lifters, stop the engine, and rotate the engine several times by hand and push on each rocker when its lifter is in the 'valve closed' position. (I.e., each lifter is on its cam lobe's base circle.) If you test like that, and all are hard, then you are good.

I ran the motor, got it up to temp to get the tick to start, shut it off, pulled the cover, and checked each lifter with valve closed; all were solid and unable to be pushed, meaning they were all pumped up.

I got no audio on the video, and the video did not show the actual sound waves in the air.....

That's odd - I just clicked the link again to try for myself, and I get the audio.. weird.
