Is this bad? Valve spring retainer pic inside
Is this bad? Valve spring retainer pic inside I pulled the LH valve cover on my 95 LT1 today. Been running fine, but there's a chirping sound coming from the general area of the LH valve cover.
Here's the only thing I found that looks abnormal:
The rocker appears undamaged, the pushrod is straight. Do I need to replace this retainer?

yah you need to replace the retainer. I would wait for more experienced people to chime in first though. They may tell you to check or replace other parts.
Got to say that's the first time I have seen that happen. I wonder if more experienced people who chime in have seen that before.

There's no pieces up in the cylinder head, which means if they're anywhere, they're in the oil pan (or washed out with a prior oil change).
I have had a rear intake oil leak (imagine that), so I pulled the intake today as well, not sure if it's related, but the intake port for that same cylinder doesn't have the "clean" area that the other ports show. I'll get a pic to explain better.
The injector o-rings were very dry and brittle, and the little plastic rings just above the o-ring shattered into tiny bits as I pulled the rails.

and get rid of that spring, check the locator, check the keepers, check the valve stem for straightness, check the seat pocket for squareness with the guide/valve.
Something is probably not straight for that to have happened.

So, am I best off replacing *all* of the springs, retainers, and keepers? Or just the one that's the problem here?
I'd either just replace the parts on that valve, or take the opportunity to upgrade springs, retainers, and rockers (1.6RR) on all.

I just drive around -- it's just a fun daily driver for me, no plans of ever going to the track. Even when I romp on it a bit on an on-ramp, it's rare that I'll run past 5K. But, if there's a preventative maintenance angle on replacing all 16, I could justify it. There's 138k miles on the motor, BTW.

Check all the pockets in the oil valley where oil accumulates with a magnet. Some pieces could be hiding in those oil pools.
Update:
I swapped out all 16 valvesprings and retainers, no underlying issues found with the valve stem, pushrod, spring seat, or rocker arm on the affected cylinder. I installed LS3 springs and Comp retainers, reused the stock locks and stock rocker arms. Bought the Comp valvespring tool which made life easy. Running great now.
