ok,
had a go at getting the bov off, no avail.... its wedged in my guard and i snapped an allan key, looks like i am going to woirkshop tomorrow.
there was heaps of mud, etc near it from a recent drift day that i went off a few times at, i think the dirt is what has made it seize, it must of been getting stuck open when it was hissing just before it siezed.
thanks for the help guys.
Evan
