The stainer that I removed from the car (1929) was of a much finer mesh that the replacement I have just bought.
Can anyone advise how fine the mesh should be?

Hello Brian,
The mesh size doesn't really matter! Its only there to stop the big bits,like, nuts and bolts and the odd cigarette end getting into the sump and then into the oil pump. The racing boys did away with them all together.

Many thanks John for the graphic description!; I'll crack on and fit it.

The size of the mesh needs to be sufficient to let the oil fall through but not too many big bits.

Having recently expolded a piston, some of the bits of which punched holes in the gauze, I was quite amazed to note how many bits the holed gauze actually caught.

Worry not.

Perhaps not all the racing boys, John. Many here fitted a thick aluminium plate which helped stiffen up the crankcase. When racing, I fitted the sump strainer from my '23, which to those unfamiliar is not like the standard strainer Brian and others have fitted. Instead of the flat skeleton frame covered overall with mesh the early cars had a tin slightly-concave solid dish with three circular tin "wells" along it's length, the sides of each well being the only parts covered with mesh. Apart from the slight stiffening effect, one could not invent a better anti-surge device. Today's trivia. Cheers, Bill in Oz
