FMIC Bumper trim question

[98gst14b]

On a 98+ front bumper the fmic is halfway covered by the bumper, I was wondering has anyone trimed out their bumper to get more airflow? Pics neone? Also another random question, can a vented bov and leaking headgasket caust knock? THanks

I hope you don't think air goes into the FMIC...

my expereince with the single diaphram 2g bov is when vented it likes to suck in air. Leaning out your already pre-metered fuel mixture will cause knock while not under boost.

If your head is leaking oil into the combustion chamber, yes that will also cause knock. Oil reduces the octane rating of the fuel. Reduced octane will of course cause pre-detonation under boost. I've had friends lose motors over it.

Did you post in the wrong thread or something?

Remove your bumper support and the black plastic strip at the top of the "mouth". Pic in my gallery.
