Most probably I identified clicking. It comes from torque converter. I will confirm that once it will be replaced.

 

Hereby videos.

 

I am not sure if I understand rocking the prop. Does it mean to rock the car forward and backward?

 

It means to move the driveshaft back and forth to see if you can
isolate any sound it may make.

 

Hi Zdicho,

The idea is to grasp the driveshaft with your hands and try to rotate it clockwise and counterclockwise, then try to push it up and down, then side to side, then pull it forward and rearward. You're looking for excessive movement or backlash that would indicate a problem with the driveshaft center bearing or U-joint, the transmission output shaft and forward driveshaft flexible coupling (flex disc or giubo), the differential pinion bearings or rear driveshaft flexible coupling, etc.





Cheers,

Don

 

Thank you for hints and explanation gents!

Tomorrow arriving toque converter! Keep me fingers crossed please

 

Used torque converter arrived but does the same kind of clicking noise... Does anybody have the possibility to access torque converter connected to the gearbox on the shelves and check if it is clicking this way?

 

It sounds like you might be dealing with a common issue in the Jaguar XJ8,
where the torque converter can cause a ticking noise. This can often be
due to wear and tear or issues with the torque converter lockup mechanism.
If you have replaced it with a rebuilt, then it sounds like the rebuilt did not
adequately address the issue.
