I made a trip after changing my oil using Motul 5w-30. During somewhat long trips, I always check my oil. Never had any leaks and never had issues with low oil. I was heading home and noticed a slight ticking/tapping noise. When I pulled into my driveway, I immediately rechecked my oil and everything seemed fine besides the now louder sound from the engine when I started it back up (video below). I drained the oil again and dropped my oil pan to be greeted by an inch of galley gasket floating around. I ordered Z1's Oil Gallery Gasket Kit as well as everything else I would think I need to replaced since I have my hands on it. I'm about to order a new engine but I want to know where should I look to see if I can rebuild this motor as well. I have some people saying it's engine knock and I have others saying it's VVEL related. Also only codes pending before tearing it down was P0300 (Random/Multi Cylinder Misfire Detected) and P0461 (Fuel Level Sensor "A" Circuit Range/Performance). After Putting it back together P0081, P0075, P0113, and P0300 are permanent. Nothing else. My car is tuned on UPREV, CAI, Test Pipes and CBE. Figured I would make a post on here before just decided to swap motors now. Any input would help me narrow down anything else I haven't thought of.
