Spring/Keeper interference with Rocker
Hello fellow enthusiasts;
I recently developed a new tick in my LA (340) engine - lloking for some assistance / expertice.
Background:
This is a mostly stock engine that has been slightly bored over, and has a different (unknown) cam. has edelbrock intake and a holly street avenger carb. No other modifications to my knowledge.
History:
Initial thought was collapsed lifter; Pulled them all, disassembled, and found one on the passenger side (side making noise) with some debris in it. Bought a new set of comp cam replacements, soaked them, installed them, and fired it up. same noise.
I did not go through thoroughly inspecting everything ( rookie mistake ) before reassembling. Upon reassembly, and making the same noise, took it back apart again. I am seeing some odd "self-clearance" scarring on the rocker buckets. Please see pictures below.
Do the retainers look like the proper retainers?
Does the scaring look like someones self grinding to you or are you in agreement that this may be the root cause of the noise?
The noise does not start right away; It only begins once things get up to temp. starts faint, then gets more aggressive. It is definitely at the rate of the valve train.
Please help me pinpoint this issue!!
Thanks,
