I just ported out the intake plenum to fit the Z1 upgraded TB's and i'm paranoid about the little metal shavings that I can't get out. I've flushed the plenum out many times and got as much as I could but there are still very tiny pieces of shavings still in there. There are no big chunks or anything, just small pieces of metal "dust" here and there. Will that hurt the motor if any of those pieces get into the engine?
