Although the noise has "gone away" now, it's still got to be worth a look.

When replaced, the problem has gone. Its a nice quiet burble from the engine.Mike and Poppyhttps://www.blogger.com/profile/14252646448078744534noreply@blogger.comtag:blogger.com,1999:blog-30116820.post-50177106019502388302011-06-08T15:20:40.193+01:002011-06-08T15:20:40.193+01:00Hi Geoff.
