          Anyone care to have a look at the pv video? Is it supposed to move and vibrate that much?

            @irongamer727 Looks like exhaust gases are leaking past the rubber oring from the bush.

            That are the bush is excessively worn and needs replacing.

                  @irongamer727 I've not seen that before no. You will wear the mechanism out like that.

                    Is the powervalve supposed to open at a set amount of revs? Mine opens just over 6k.

                          @irongamer727 Yeah, the valve muffles the exhaust sound, when you pin it, you're blaring the combustion through the expansion chamber.

                              What do you think might be causing it to be that loose? Everything, even the screw holding the pv sides together is securely fasten.

                                It's leaking oil and even exhaust gases..

                                  Yeah, it'll be down on performance if that's the case.

                                  Are you sure the other side of the powervalve is fastened properly?

                                      @irongamer727 there's play between the pv and the cylinder. Is that normal?
