Subject: Re: cross shaft oil supply
The part indicated in the image after a second inspection was found to be only some slight restrictor, it has not a full bore but is half open but a wire can be pushed through. And it was not the reason for the whining sound.
I also checked the axial alignment of the exhaust camshaft, first trying with the adjustment screw on the front of the "P" plate, with no effect. Then I removed and refited the brass gear which drives the rev counter on the rear side of the exhaust camshaft. (On other 2ltrs this sits on the inlet camshaft and there is a thrust pad on the exhaust one instead). But at the same time I tightened some screws on the carburettor flanges. The noise was gone ! But I can not tell which of the two was the reason. Club member John (B29) helped much again with suggestions. Other discussed source of a whining sound was the dynamo.
