All good advice from
@msvela448.
The ticking in that video does sound very much like a failing cam follower. It's rather early to have that problem at just 100k miles and I suspect a previous owner might have either thrashed the engine a bit too often or neglected oil changes.
I also noticed that your temperature gauge is above halfway in addition to the tachometer not working. Has your engine recently started running hotter than normal? Does the cooling fan switch on normally? You may merely have bad stepper motors on both of those two gauges but you'd definitely want to rule out a potential overheating problem.
If you're planning to keep the car long term, you'll have to dig deep into your pockets to buy this shopping list of parts to fix your problems and prevent future catastrophic engine damage.
1. A pack of four or six new x27 stepper motors from eBay.
2. VCT solenoids.
3. Ford Performance Rocker Arm Lash Adjuster Kit: M-6529-3V.
4. Ford Performance Camshaft Drive Kit: M-6004-463V.
5. New OEM '13-'14 Shelby GT500 high pressure oil pump (Ford part no. DR3Z6600A) with new OEM 3V oil pump pickup tube (Ford part no. 4R3Z6622AA.
While the oil pan is off, I'd advise you to inspect the rod bearings. If the engine's suffered previous abuse, they may show advanced wear and even if you replace all the parts I listed above, you could still have low oil pressure problems due to excessive bearing clearances.
