Hi everyone my started making a knocking noise straight away I thought that I had blown something in the engine. I had my mechanic have a quick look, at idle the knocking is there depress the clutch the noise goes away so he thinks it might be something in the clutch which only 40 thou old exedy had. Idea's anyone.
Cheers.

We have a ute at work with a worn thrust bearing. Makes a clicking/knocking sound which doesn't sound healthy and is only when idling. It's like a $60 part however, labour will be the killer here. Would be a good time to upgrade the clutch if you haven't already.

Throwout bearing is a goner.

I've been told by a mechanic that it might be the spinning cog in the gearbox
That engages with the clutch has spat a tooth or two.And was told that I should not use a heavy duty clutch as the clutch is the breaker saves the box

He's right about the second part.
Use standard clutch with 5 speed gearboxes.

Mechanic has got the gearbox out and says the box needs to be stripped and may start to cost to much and I may need to get a second hand one from the wreckers. Would it easier to maybe go a STI 6 speed.
Any suggestions would helpful.
Cheers.
