That alu plate over the half time gear is a dam for having a higher level of oil in the timing chest, so the old drain hole was plugged and a new hole a bit higher up is meant to raise the level - or so I believe. Time and road tests will tell but this will be not before next year. The oil feed into the crank end is a hardened and spring loaded turning with a 45 degrees taper sitting on the crank end, no extension into the crank then. I have seen that elswhere, don´t remember but liked that a bit - to be tested again.
