BB hydraulic lifters
I'm going through an original 70,000 mile 383 engine that has sat for almost 30 years. The cam and lifters look great, but I noticed that 3 of the lifters had orange paint daubs on them. Since several of the lifters had not bled down I took them all apart for cleaning and re-installation.
Interesting that the 3 with orange paint had different internals than all of the others:
