I pulled the cam follower to check how it was doing. It’s been quite a while since I last checked. I’m estimating the total mileage on this to be about 45,000 miles. This is only the second cam follower this car has seen. Nonetheless, the wear is excellent and I’m popping this one back in. I’ll check back in 10,000 miles, which this should easily last. The DLC coat is still not completely worn through in the center.
