Thank you Peter and Malcolm for your suggestion. I will, of course check. However, you will see in my original post that this noise is a distinct light tapping noise that occurs between drive and overrun, exactly when one would expect a big or little end rattle to occur.

Between drive and overrun is when problems in transmission such as prop shaft occur.

Interesting. Leon drove the car yesterday for the first time since the engine was overhauled and thought that the noise was in the gearbox.

If it is the gearbox -4speed?? My guess would be excess endfloat in the layshaft bearings.

Check the oil level in the box before doing anything else.

Aye
