Addicted To Boost Posted February 7, 2011 Report Share Posted February 7, 2011 Just clean the area really well and be sure to get the new brown silicone oil pump drive seal from GM... that one won't leak. Other than that, grab a throttle body gasket, its nice to have the TB out of the way when doing this job. Quote Link to comment Share on other sites More sharing options...
