mitman2501 Posted September 2, 2016 Share Posted September 2, 2016 Hi all newbe so have a few Qs So when on idle I can hear a loud knock that last seems to be coming from the low end of the gear box. This doesn't happen when cold only after a drive. Gears are fine in fact feels lovely also not long had a new clutch fitted! Any ideas!

Zeezeebaba Posted September 2, 2016 Share Posted September 2, 2016 Anything underneath fouling the shaft or similar? Quote Link to comment Share on other sites More sharing options...
Richf Posted September 2, 2016 Share Posted September 2, 2016 Did you have a new flywheel fitted with the clutch ? What do you mean by "low end" engine or prop end? Quote Link to comment Share on other sites More sharing options...
mitman2501 Posted September 3, 2016 Author Share Posted September 3, 2016 (edited) Newbe Qs Only on tickover the car is stationary I can hear a knock sound coming from gearbox now and again only happens when warm and the cars in neutral. I can hear it more with the bonett open, but can feel the knock if I hold the shifter drives fine not long had a new clutch fitted by last owner. Any one?

350_Jer Posted September 3, 2016 Share Posted September 3, 2016 Hi, I was a little worried when I first got mine, but they all seem to be a little rattly/noisy from the transmission from what I've read on here. Have a read through this: http://www.350z-uk.c...le#entry1231370 Helped put my mind at ease! Quote Link to comment Share on other sites More sharing options...
Zeezeebaba Posted September 3, 2016 Share Posted September 3, 2016 This may sound silly but does it disappear at slightly higher revs e.g. With the air con switched on? Is it very intermittent and sounds like the car is going to stall but doesn't? Quote Link to comment Share on other sites More sharing options...
mitman2501 Posted September 3, 2016 Author Share Posted September 3, 2016 been reading about the throw out bearing it's common and been told not to worry about it, but it doesn't sound Gd Quote Link to comment Share on other sites More sharing options...

mitman2501 Posted September 3, 2016 Author Share Posted September 3, 2016 No it's only when warm after a drive this starts car drives fine Quote Link to comment Share on other sites More sharing options...
Zeezeebaba Posted September 3, 2016 Share Posted September 3, 2016 Once you've had a drive let it idle then put the a/c on. If it stops doing it it may be a normal feature of the car. Mine on normal idle used to do this when warm as the revs fluctuated slightly and the knock could be heard around the gearbox area. Putting the a/c on means it ticks over at slightly higher rpm and the intermittent knock ceased. I've just had all my bearings and clutch replaced and it no longer does it.
