Please help me diagnose. I ran this 8th gen civic si k20z3 mistakenly with little to no oil in it, no engine light or codes popped up. The oil level showed at the tip end of dipstick but barely. I drove it hard and hit vtec everyday for 2 weeks before i checked my oil again. But now its making this sound after a long ride. No power loss in the high end RPMs, little power loss low end What do you think it is? Timing chain/Vtc, crank shaft bearing, bent valves?
