need help with boost leaks asap

**Shane@DBPerformance** · 03-03-2009

Often BOV and throttle body elbow flanges are warped and need to be run on a belt sander to make them flat. I usually use only RTV and no gaskets on things like bovs and throttle bodies that don't want to seal. I have had better luck with just RTV vs gasket + RTV, but every case is different.

the thing with the tb is that when I did the head I sanded that very well (not with a belt sander) with a perfectly flat sanding block and even removed the studs from the intake mani and sanded that good and checked them with a straight edge and there wasn't any noticeable gaps
but obviously I didn't do a good enough job
