Isuzu DMax loud idle noise

Urgent Help!

I have a 2014 2wd manual Isuzu DMax eith 142xxx kms on the clock. When in idle (and generally when the car is warm), the ute makes a loud crunching type noise. When I push the clutch in, the noise goes away.

Have taken to a mechanic who said gearbox bearing is collapsed so need a new gearbox & would put a new clutch in too.

Went to a Gearbox specialist for another opinion, they said it is not the gearbox at all, it is only the clutch that needs replacing due to a clutch bearing.

Anyone else have a similar problem and what was the outcome?? I dont want to replace something that doesn't need replacing!

Cheers!

My money is on the clutch bearing. First mechanic heard you coming

Same situation with me. Is it done? I used to change all the bearings in the gearbox, change 1 set of clutch and change the pilot bearing as well. Problems still exist. Only when it is hot. When it's cold, the noise is gone. Someone told me, clutch cover, but that is also a new replacement, up to 2 times I change it in 1 year because I want to get rid of that sound. But that sound is still there.
