I killed 3 cam sensors due to a POS china made "High-Volume" timing cover that I purchased from Full Throttle quite a few years ago. Turns out the cam sensor hole in the cover was drilled slightly "off" causing the cam sensor to not mesh with the cam gear properly. I wondered why it was a bit tough putting the cam sensor in but it didn't click till I saw multiple posts about the same problem. Switched to a TA timing cover and my oil pressure at idle went up 10psi and the cam sensor just falls into place with no effort!!! Now I go out of my way to buy USA made parts where possible, even if it costs 3x as much, its worth it. TA Performance parts for me, top quality company.
