My Ulsteroid is fitted with an early coil engine and has always had an issue with oil leaking from the rear main bearing but this has now got a lot worse.
Although I built the engine myself some years ago I can't really recall how the rear bearing is sealed and it looks as though it could potentially be either a felt seal or an oil thrower which, as I understand it, directs any oil into a cast aluminium cover from where it drains back into the sump.
If it is this oil thrower set up then I'm at a bit of a loss to understand why it would get much worse relatively quickly.
As I've hardly driven it for 2-years now and every time I do so another problem arises I really don't want to take it off the road and strip it down yet again unless I have the parts I need to hand.
The engine number is M 132714 which I think means it probably dates to 1929 or 1930 but would anyone be able to date this more exactly and / or guide me on the likely parts required?
I'm fairly sure it is oil from the engine rather than the gearbox as it's very black as it trickles onto the garage floor.
