Opinions ranged from tappets, main bearings, idler / tensioner noise etc, however Russell used a long screwdriver as a stethoscope and correctly identified it as piston slap. He suggested the engine would probably out live me and was nothing to worry about at this stage, but being a picky so & so I wanted the noise gone, so he pulled the engine apart and sorted it .

It's worth mentioning, Russel is mobile and has been known to travel a fair distance for jobs. This week he is due to be in Liverpool (though I guess that plan may change with current restrictions). Having said that though, I guess a long trip just to listen and diagnose may not be the most economic approach.

Dry tappets?
