So I got a 09 Silverado 5.3 vin M. I had a real bad misfire on cylinder 4 so I started by swapping coils, misfire did not move, tried plugs, nope, cylinder leak down then led me to the cam or lifters. So I bought a lifter set of 8 regular, and 8 AFM. Started to take it apart and found a flat spot on cylinder 4s AFM exhaust valve lifter, then I noticed the cam was ruined from the lifter, got a new factory cam from Chevy and installed everything fallowing Mitchell shopkey to the T. Started it up and it went from sounding like a 5.3 to sounding like a duramax. The tapping is on all AFM lifters. When I go in and deactivate the AFM lifters with my scanner the tick goes away completely. No misfires, runs great, just ticks. I since the. Went and replaced the VLOM. Any ideas?
