What automobile are you working on and what year? It matters.
If it is a Pontiac, the Cam Sprocket was aluminum with nylon teeth from about 1965/66 through around 1972.
I know too well. I once owned a 67 GTO, HO 4 spd. with 70,000 miles when it shut down. Many nylon teeth had been worn down and a few broken off.
I had other reasons to pull the engine, so now it was a must.
I already knew that a Pontiac Dealer service said if the nylon gear needs replaced you are advised to drop the oil pan to clean the nylon debris.
When I pulled off the pan there was plenty of small nylon chips that had gotten into the oil pump pick up screen.
These factory sprockets were a poor design.
Good luck on whatever you do.
Just remember, on a Survivor car don’t strip, paint, change anything except that timing set and factory style gaskets to preserve what’s left.
