I forgot to even mention the ratchet system. ****
The common issue on these is that they do tension correctly after start up but that ratchet system simply doesn’t adjust. There’s a way to compel a ratchet advance with the engine not running if the ratchet is woking and it “needs” to adjust. This is not foolproof and if the ratchet sticks or just stops working, you only have proper cam chain tension once full oil pressure reaches the tensioner.
I lost a tensioner on my ’97 Cobra; it just freaking broke, was basically flopping around, but hadn’t broken off. The car ran like cr@p for about the 1st 2000 rpms, then was smooth as silk and seemingly full power and it took my Ford Master Tech literally months to diagnose. The failed part was laying in front of him for weeks and he couldn’t determine the passenger side tensioner wasn’t doing anything. He did eventually get it, and replace it. Very frustrating.
