The oil is not glittery. My downpipe should arrive tomorrow, but I'm afraid that won't fix the issue. I'm on the hunt for a vacuum leak because I hear hissing, and my MPG's are really bad, and absolutely no power when above 2k RPM. There's probably lots of issues, just trying to tackle them one at a time. But like I said, no glitter in the oil whatsoever. I can rev the engine in neutral pst 2k rpm, but the engine won't go past 2k when I'm driving. Also, the idle is around 600 or 700 rpm, but every few seconds it lowers a bit, then stabilizes. Probably just need to take it somewhere.
