Please don’t run this camshaft again without a more permanent fix.
The pin and hole got abused after the single bolt came loose. The pin arrangement is not intended to carry that load. I always red lock tight these bolts during final assembly and torque.
A friend just finished rebuilding his Chevy after a timing chain failure. Looking at his, the cam bolts never loosened but the pin slid out and got caught in between the timing chain and crank gear, judging by the witness marks. Broke the chain and bent a bunch of valves and pushrods. Same thing happens on 5.9 Cummins Diesel engines.
Edited to fix spelling. Valves, not bales. Sorry.
