Yea but if idve said that id be wrong!

They dont make a similar noise, they make the same high pitched ptshhh as all other piston BOVs, the chatter noise you often hear when running them BOVs IS chatter, and nowt to do with the BOV apart from it not letting enough air out to stop chatter, i explained that in the post.

There was NO in that post at all, only in the reply to the one when u got stroppy n tried to give me grief.

The wasnt at you specificly, it was cause i hear this soo often from people it drives me mad, a bigtime car tuning urban myth.

The way your replys were worded you was getting huffy for being corrected, not cause of how my post was worded (there no or any kind of pisstake in there at all....).
