BOV ? not the everyday one. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

i have the Sard BOV and after my car warms up, the bov makes a broken noise (tss tss tss tss tss), but after a while it then starts making the normal solid sound (ppppssshhhh). my car is less laggier and more responsive with the broken sound... it feels like my BOV has to warm up too..(which seems wierd) anyone know why? perhaps my BOV is a little too loose? i dont stall or stumble or anything.

thanks

is it on hotpipe if so it may be heat related, metal expanding when it gets hot, maybe the flang sepearates or something

yes it is on the hotpipe.. but for those familiar with SARD BOV, it is not your conventional WELDED flange... it is held on by a hose and 2 clamps (one to the BOV and one to the welded nub on the hotpipe.)
im also wondering if it has anything to do with the dual drive design?
