Lots of folks having issues with hydraulic roller lifters rattling, collapsing and bleeding down too fast in their LA flat tappet designed small block...mine included.
The issue with my 408 is not the oil band coming exposed at high lift but more of the inner piston to inner bore wear causing excessive leak down over time...probably due to the excessive side load the push rod angle imparts to the lifter. I'm on my third set of hughes retros...thank god I only had to pay for 1 set.
What brand/ part number solid rollers are you guys running in your non roller LA? Are the lifter bores bushed or not? Did you have to grind the block for link bar clearance?
This topic could help many in their search for a fix for the hydraulic roller issues I/they, am/are having.
