1JZ stock BOV.. normal sound?

hi all.. got a JZA70 auto.. quick question about normal operation of the stock BOV.
The car is an auto, im sure this makes a difference to the following.
Say im running perhaps 5psi boost, on release of the throttle to say 20% (when backing off or whatever) the BOV will release in multiple passes, ie it releases once, waits a split second, releases again, waits a split second, releses again, waits a split second etc etc .. you get the idea.. until all the pressure is released, getting gradually quieter each time. I cant get a sound file so heres a the best i can do...
'Psch...pssschh....pssssccccchhh ....pssssscccccchhhhh.....pssssscccccchhhhhhhhh' . Sometimes it does up to 15 times in the space of three or four seconds before it stops. Sometimes it even gets 'stuck' and carries on forever until i release the throttle completely, whereupon it sorts itself out.
On a high boost (say 12-15 psi) and a total foot off the throttle, it will release in one go.. a quick, short PSSSCCHHH burst.
Right.. is this normal operation? Could I have a nackered BOV and the repeated released be the turbos stalling? I've got stupidly expensive hybrids and dont want to nacker them.
Anyone? Remember this is an auto...
Cheers
