thegoth 5 Posted January 4, 2012 Report Share Posted January 4, 2012 If you mean the lozeng shapped silencer, yes. As i thought mine might be leaking.With the use of jubilee clips, it's easy enough to replumb the ISV with the existing pipework. Doesn't sound any louder for it! Link to post Share on other sites
Jogort 0 Posted January 4, 2012 Report Share Posted January 4, 2012 So it's no issue to remove this ? I replaced mine a few months ago after it blew off :-O So I just remove and use some jubilees and extra hose if needed ? Always seems to be hissing anyway. Link to post Share on other sites

russj249 2 Posted January 4, 2012 Report Share Posted January 4, 2012 I ran mine like that for ages.. one day I started it and it blew the box to pieces, so bypassed it and was all ok, and I did get a sucking noise that sounded like an air leak, but it actually went strangely enough if you put both hands on top on the inlet manifold.
