The valley cover and valve covers are painted?
This isn’t the first time this motor has had a lifter problem and it was probably rebuilt and put back together using AFM parts but didn’t properly address the cause of the failure.
There are electrical anomalies that can cause the AFM system to malfunction resulting in lifter failure. I understand this a mostly overlooked subject and I’m not well versed in it so I’m mostly speaking from memory but that can be a cause of reoccurring AFM lifter failure.
Those cam bearings look incredibly good so maybe it was rebuilt recently.
I painted the Valley cover and valve covers during COVID because I had an oil leak and the VLOM bolts were so loose i could turn them by hand.
Then my dumb a$$ broke a plastic connection on the VLOM so i had to buy new one and had extra paint.
I bought this car with about 80k miles and now has a bit under 180k. So I wonder if the previous owner had to have been a slob if that engine blew on him before me.
I even painted the 4 pot brake upgrade gm blue. Remember I mentioned I can be extra sometimes.
When I reconstructed my 02 Tahoe engine the mains and rod bearings had 285k and my Mechanic neighbor who tutored me couldn't believe they looked almost new.
So i guess its time to reassemble the rest and not mess with the bottom end. Although the wife gave the green light to redo the rest. "I know its going to bug you" is what she said. Thats as close to yes honey spend the money and buy the new bearings and ARP bolts
