I have a question for those of you that have suffered the dreaded AFM lifter failure. When this happened to your Avy, did it tick all the time or just at startup until it was warm?

I took a flashlight and had a buddy roll the engine over by hand very easy to do with the heads off since there is no compression and shined it down the lifter holes. Cam looked fine.( no wear on the cam lobes) As i shouldve noted before the lifter was actually collapsed. When i start the truck cold i notice a little tick but within seconds its gone. I also replaced the original afm solenoid with one from autozone. I do believe there was a TSB from gm about those as well.
