Fuck the F4, I'm more concerned with why you know that sound....You know the sound an automatic transmission makes when you jam it in park while rolling?
Yeah that's about what the rattle in the F4 escalates to when you rev it :rolf:
Okay, so I tore it down, reset the timing, rotated the engine several times to make sure it stays in time, and rechecked the valve clearances. I see nothing wrong with the engine now, so when I put this fucker back together I expect it to run better :lol:
I feel confident it needs the FPR and I'm sure it could use the throttle body sync, but at the very least I'd appreciate it if it wouldn't run like an air cooled beetle :lol:
