What’s up guys, i’m new to this forum so forgive me, but i really need help. So, story of the car, its a 2000 V6 mustabg, that I swapped to a 97 4.6. I bought the motor, did an overhaul, all new bottom end bearings, bolts, oil pump, rings, etc etc. Originally, when i built the motor, i had NPI heads on it, stage 3 comp 270 cams, trickflow lash adjusters and that was about it. Well, I recently decided to do the PI head swap. So i picked up a set, had the machine work done on them, ported and polished them, then installed them. Well i got the car to run, and when it first fired up it sounded beautiful. Ran great. Proceeded to put everything else back together, and then i started it to drive it, and i had a tick/ tapping noise, as can see here :

So I was told by a mechanic it was just a lash adjuster. So i tried to drive it back to my house, and it made it about a mile then died. On the side of the highway, I diagnosed it to be timing chain tensioner. So i got it to a garage, put new tensioners, guides, and chaines on, and the car fired up. But the ticking was still there! So then i bought lash adjusters, swapped those out, and the ticking was quieter, and would go away with RPM. Well i quit messing with it, and came back a few days later, and the car fired right up, and had absolutely no noise at all. So, i drove it, and it would be intermittent. But the car ran great! I was about to pull back into driveway and it died and now will not fire up. I pulled the valve cover, and here is what i found :

So, what could be causing that follower to be loose? The follower bearings are fine, already checked that. If the valve is stuck, could it be bent? Mind you, the machine shop said the guides look fine. I don’t know what to do!
