This current follower has 30,000 miles on it, 15~20,000 of it on APR Stage I. I changed out my first one at around 57,000 miles. This new one still has not developed any appreciable wear. The DLC coating is still there, unworn for all intents and purposes.
There has to be a rhyme and reason to all this. Is it really just people using poor oil? Not breaking the car in properly? Too early for the first oil change? Manufacturing flaws?
While there was improper cam hardening with the A cams, the B cams supposedly remedied that problem and there are still reports of failure. My car does not have any accelerated wear. Other cars chew them up in as little as 10,000 miles.
My advice would be to check at least every other oil change until you’ve established the rate of wear. Then you can increase your intervals. Keep in mind that wear is also accelerated as the cam follower wears down.
