Ruddi444 Posted October 13, 2015 Share Posted October 13, 2015 Noticed a weird noise happening, when I release the blitz dump valve normally or heavily on boost sounds normal, but if I slowly release it , or release it out gently it begins to chatter or shudder first? And something sounds not right like air escaping or something? But I have checked all hoses! Recently fitted a hks mushroom and its a standard glanza so any ideas or shed some light? Much appreciated Quote Link to post Share on other sites
asbo-v Posted October 13, 2015 Share Posted October 13, 2015 Manifold cracked? Have you checked as the standard ones are prone too them cracking. Quote Link to post Share on other sites
Ryan_EP82 GT Posted October 14, 2015 Share Posted October 14, 2015 I thought thats wat the blitz bov does? Chatter low throttle and dump at full boost? Quote Link to post Share on other sites

mart1 Posted October 14, 2015 Share Posted October 14, 2015 I had a blitz dump valve was the same on mine, it just didn't suit my glanza auto so got rid and got an original standard one on it now, much better. Quote Link to post Share on other sites
