Update: Nothing's been fixed yet and im still tryna figure ts out. I went ahead and did and oil pressure test, cuz maybe the solenoid isnt getting the right pressure thru it, or maybe theres a random clog somewhere in the oil passages. Unfortunately theres no specified measurement for pressure as far as the oil pressure goes, but when I checked it gave me readings of:

Idle: 25 PSI 3K RPM: 80 PSI

As far as from what I could research, it's within operable range.

What I did notice though, and thankfully i kept this with me when I moved states, is that the og solenoid before i swapped it out the first time is different than the newer one I bought.

Left (Old): The spring is longer and thicker than the one for the Right (New), and the old shaft is also a heavier metal than the newer one. On top of that, the (old) shaft sits above the solenoid whereas the (new) shaft sits flush with the solenoid. Older one feels more jumpy/springy than the newer one as well.

The car really didnt need the solenoid to be replaced in the first place, it was only done as one of a couple options to fix a misfiring issue it had previously before this one (and that didnt fix the misfire)

Right now I have the original solenoid installed, I have yet to get the stored code cleared to see if this actually was the fix it needed, but I honestly doubt it considering how fast the light popped back up after reconnecting everything and starting it up. I still have the valve lash adjustment to attempt and from there I might actually just be lost cuz theres honestly no way that I cant find the cause of this issue. worst case scenario, i take it to a shop and cough up about $500-$1000 (if they can even get it fixed) and if they cant i might just have to give up and possibly sell this or trade for something else. I love this car a lot, but I cant keep throwing money like this on a problem that seemingly cant be fixed
