Some further work on the latest Daimler Sleeve Valve engine.
Having removed various fittings, the sump has been lowered to assess piston removal.
The previous engine would allow the pistons and rods to withdraw downwards past the crank. Unfortunately this slightly later engine has an oil deflection tray which does not allow access to lower the pistons. To remove the tray, the block has to be removed, followed by the the sleeves (these require the removal of a pin from the little con rods, this pin is held by a very fiddly taper pin, as on the previous early engine). Once the sleeves are withdrawn up and away from the piston, the tray can be removed and the piston rod assy can be withdrawn. Contrary to normal practice the sleeves must not be cleaned more than the absolute minimum as the grooves machined into the sleeves deliberately promote natural carbon build up to form a "natural " seal.
