Hey all,

I'm currently pulling my engine apart to get to the bypass valve, to check that it's closing properly, and found that my throttle body valve isn't closing 100%.

It's approx. 4mm off closing fully (I can see a line in the carbon where I suspect it used to sit), which is leaving a small gap round the butterfly valve.

Is it worth adjusting so it closes fully, or is this normal?
