perhaps the rockers aren't adjusted properly.
That would be zero valve lash. You only use a feeler gauge on solid lifters.
no
It has adjustable rockers.
It has adjustable rockers.
put the lifters up rite in a can of motor oil and let them sit for 30 mins
yes like 350 engine
pull the cam and lifters
5,000 RPMS. If the lifters don't float out first.That would be a safe range as far as RPMS. go.
Just the lifters and gaskets. It would me smart to replace the timing chain and gears too.
Exhaust leaks, bent pushrod
It's not recommended to change just the lifters. The cam and lifters should be replaced together. To get at the lifters, you can remove the rocker covers and intake manifold, loosen the rockers enough to get the pushrods out, then pull out the lifters.
It means the lobe is worn off of the CAM SHAFT. Need to replace cam and lifters.
