In assembling the third piece on a 912, there is a paper gasket which is used between the case and the third piece. In addition, there are 4 seals...2 which go between 3rd piece and the left case side, an additional smaller seal just above the crankshaft gear and then there is a seal that seals the oil collection tube from the bottom of the crankcase to the oil pump. this is the one I am concerned with. Gasket kit comes with four .9 inch (.145 diameter) o rings. Seems inadequate. Seems small and although critical since if this tube is not sealed properly, oil pump would be sucking air. any thoughts or advice. Are these the correct seals?
