big dilemma: low oil pressure..THOUGHTS?

hi guys.

my car shut off out of nowhere when I came to a stop and it barely restarted. I noticed the engine temp growing quickly by ~1 degree/sec, so I pulled over.

No leaks, oil level is fine. I start the car and notice 2psi of oil pressure at 500rpm. no engine noises yet.

I had to get home, and limped myself home staying between 1k-2.5k of RPM. Going over 2.5k RPM resulted in rapid engine temp rising, and going under 1k stalled the car. I had super low oil pressure limping back home. Stop lights and traffic were a pain, as I modulated gas pedal for the car not to die. The engine developed a rattling/ticking noise which was exacerbated with giving it any throttle. codes: P0365, P0011, P0014 (mivec control valve issue)?

This has all happened after I got my valve cover powdercoated. There seemed to be some sandblast material in the baffles (don't know if this is related to my problem).

TL;DR:
-oil level fine
-no leaks
-no oil visibly being burnt
-low oil pressure
-car stalls <1k rpm
-car gets hot >2.5k rpm
-p0365,p0011,p0014 (mivec issue?)
-valve cover was powdercoated prior (sandblast material in baffles)
-rattling/ticking noise that is exacerbated with giving it gas
-AFRs looks fine, and the car can build boost

any help whatsoever is appreciated..entirely bummed out.

Engine is toast and you did more damage by driving it when you knew there was no oil pressure. Probably an expensive lesson.

Stop driving it, time to tear the motor down.

This is why detective coating told me to be weary of anybody not removing baffles when powder coating. No matter how good of a job there is a good chance of sand or cleaning material getting stuck.

My vote also. Driving it with low oil pressure FUBARed the engine for good. Bummer, dude. Good luck getting her fixed!.

Will crack open the oil filter and maybe get a uoa. she didn't make noise on a coldstart (also 60psi oil pressure)

You can just drain the oil. With all the metal that's most likely in there, you won't need an oil analysis.

Wait, are you saying that it is a bad idea to start and operate a mechanical device that relies on stable oil pressure...with no oil pressure?

Yeah man, these things happen. Look at the bright side...at least you probably have a usable core. That is more than most people in your position can say. Sorry to hear this, though.

need a new head, crankcase, bearings, etc. going with a straight swap.

besides the timing chain revision or plastic valve cover, are they any surprises I should know about when swapping a 2011+ engine into my 08 (e.g. engine mounts, ECU issues).
thanks for discussing my ill fate xD
the potential swap is a 2014 engine

It will go in without an issue. Use the electronics and ECU from your current motor as much as is possible.
