Daston Posted March 2, 2007 Share Posted March 2, 2007 Hi guys Had my car for a couple of weeks now and have noticed somthing that I am not too sure about if I floor it in 2nd gear it sounds as if my bov is dumping as if air is just shooting out of it, my boost gauge shows that pressure is increasing tho but surly this isnt right.... My bov is a blitz one not sure on how old it is tho is there anyway I can make it harder to open as to me it would seem that its opening prematurly.

Guest boostcontrol Posted March 2, 2007 Share Posted March 2, 2007 I had a similar problem(?) on my last car (S14a), thet was a bailey BOV. Never suffered any long term effects of any kind, but nobody i spoke to had any clue what it was. Sorry.. not a very helpful post this. Link to comment Share on other sites More sharing options...
uk-rich Posted March 2, 2007 Share Posted March 2, 2007 are those blitz ones prone to leaks ? Link to comment Share on other sites More sharing options...
Guest mk47 Posted March 2, 2007 Share Posted March 2, 2007 Not too sure on the blitz one, but recently I had someone having the same problem.. turned out the bov required a new spring (around a tenner) and that solved it. Link to comment Share on other sites More sharing options...

Homer Posted March 2, 2007 Share Posted March 2, 2007 The old style Blitz ones were prone to sticking, they can be easily dismantled and oiled up a bit. That worked on an old one of mine and is still working to this day on another members car. Link to comment Share on other sites More sharing options...
wez_p Posted March 2, 2007 Share Posted March 2, 2007 unless it's just enough of a leak for you to able to hear but not enough to stop boost increasing, is it possible it's just the sound of the induction/turbos? my Apexi induction makes quite a bit of noise when you give it some Link to comment Share on other sites More sharing options...
Daston Posted March 2, 2007 Author Share Posted March 2, 2007 yeah it goes from a whining noise to a whooooosh when boost goes over 0 bar. Link to comment Share on other sites More sharing options...
robwilliamst3 Posted March 2, 2007 Share Posted March 2, 2007 Yes the blitz DV's sometimes gets bunged up and causes this. Also Blitz recommend a replacement "harder" spring for anything over 1.2 bars. The blitz part number is 70997A Link to comment Share on other sites More sharing options...
Daston Posted March 2, 2007 Author Share Posted March 2, 2007 how hard is it to take apart to unbung and is a good old squert of WD40 enough? Link to comment Share on other sites More sharing options...
robwilliamst3 Posted March 2, 2007 Share Posted March 2, 2007 http://www.mazdas247.com/forum/showthread.php?t=123618234 Sorry wrong link... that’s a for a HKS Looking for the blitz guide. (a little later) Sorry can’t find it! But I remember it was just a simple case of removing the 4 top bolts, then Removing the spring and plunger and using some wet and dry and wd40 to clean the bore.
