Morris Minor Owners Club

Only noticed this on the way to the National and on the way home.
It starts at 20 in 2nd, 30 in 3rd, and 40 in top so I assume it rev related allowing for the wiggly speedo but the sound is like a noisy tappet or possibly two it doesnt get any louder with speed just faster and the performance is as normal and nothing seems untoward apart from the noise I have checked the valve clearances and they are fine, any thoughts, its a 1275cc by the way.

Blown exhaust manifold gasket can give a ticking rattle. Feel for a blow with the engine running in this gasket area.

Timing chain - or dizzy ?

Not the timing chain as it only does it when moving and the dizzy is a new one, well check the manifold tomorrow.
