Gearbox issue?

Recommended Posts

The other day i was driving the car pretty hard and it started making a ticking noise from the front of the gearbox/back of the engine.

You can hear it while the cars ticking over and driving, also it gets louder when you dip the clutch. Yesterday there was a loud scraping noise like something rotating and then it went. Now the gearbox has a slight shake when ticking over and moving off. Has the input shaft bearing gone maybe or something on the flywheel? I haven't heard anything like this before so its been quite hard for me to diagnose the problem lol

 

Edit this is a W58 box

my old w58 started doing that.

 

i also thaught it was comeing from inside the bell housing,

 

i changed the clutch , thrust baring and pilot baring. put it all back togetrher and it was still the same , so back off and delved into the box itself

 

turned out the be the barings in the centre plate of the box

A pilot bearing just goes round a nd round, it's fixed in the end of the crankdhaft. It only goes round when the clutch is depressed enough to free it. With the clutch pedal "up" it doesn't even turn. Sounds more engine related to me, a misfire probably. Try pulling each injector, coil pack or plug lead off in turn and see if there's a dead cylinder.
