Guest steve09 Posted September 23, 2006 Just recently heard a knocking noise coming from the bottom of the engine just behind the number plate,seem to hear it more on tack over anyone know what this could be? Share this post Link to post Share on other sites
mickie 3 Posted September 23, 2006 maybe something to do with your crankshaft, if i were you i would get it looked at pretty quick Share this post Link to post Share on other sites
matt1900 0 Posted September 24, 2006 if it's a proper knock, then i'd say big end shells are shagged, if it's more of a rattly knock that isn't consistent with engine speed, then it could be the release bearing on the clutch or input bearing in the box.

Gtautotech 1 Posted September 28, 2006 (edited) I've been told you put your foot on the clutch, and the knock should go away if it is the input shaft from the gearbox Is this true? Edited September 28, 2006 by Gtautotech Share this post Link to post Share on other sites
Gtautotech 1 Posted September 29, 2006 ANYONE? I double checked my cambelt last night as i had some pinking that has now gone ( think the belt was too loose ), i've now only got a small rattle from the bottom end/gearbox i tried the foot on clutch thing and the noise didnt stop so think ill have to remove the box then start the engine again to see if its still there Share this post Link to post Share on other sites
Gtautotech 1 Posted October 3, 2006 it was my big end shells and the crank sheels are even worse Share this post Link to post Share on other sites

Faz85 0 Posted October 3, 2006 I've been told you put your foot on the clutch, and the knock should go away if it is the input shaft from the gearbox Is this true? Thats correct mate, if its the input shaft to the box, then the noise would "dissapear" when the clutch is pressed in, and if it was the clutch release bearing the noise would "appear" when the clutch was pressed in. However, these noises are more of a grumbling than a knocking. Hope this helps Faraz Share this post Link to post Share on other sites
