VADER Posted October 1, 2011 Report Share Posted October 1, 2011 Leak sound like it is coming from around the throttle body but a little from the underside. I don't have the car yet. I just bought it and know nothing about these cars or engines so any help would be great. By the way,,, my name is Kris and am a new owner of a 1993 Z34 Black with a grey gut 2 dr. coupe. Whats this I read about an intake manifold swap??? Any before and after pics available? Quote Link to comment Share on other sites More sharing options...
virtuetovice Posted October 1, 2011 Report Share Posted October 1, 2011 Try checking the PCV valve, if it popped out the leak can be quite loud. Quote Link to comment Share on other sites More sharing options...
