Engine noise

Post by Nvm » Tue Jun 11, 2013 9:27 am

Hi everyone ( who reads this)
Advice needed...
The issue(s)I have are
1) the idle revs sit at about 600. Not overly concerned but might relate to the following...
2) just done a 200 mile run and the engine sounded different than usual. It
sounds a bit like when you tape card to your bike so it hits the spokes (when i was a kid, obviously I don't do it now). Not very loud but there all the same and but sometimes can't be heard.
3) when reducing speed so no pressure on accelerator and coming to a stop it
sounded like issue two above but more rattley reducing down. It starts and increases with acceleration then I can't hear it and issue 2 tends to start.

I tried to describe best i can but. Do you have any ideas, Cambelt or something else?

Cheers all nvm

Hi
Have you tried driving a short distance with the passenger seat held back, and the hatch open so that you can hear the sounds a little better (a suitable accomplice in the rear holding the seat is good) ???

Hi,would be worthwhile checking All the belts and the crankshaft pulley,also the exhaust manifold for broken studs.



Cheers.
