Look at the draught tube on the top one. No curve or move upwards just to even try and return oil vapour to the sump, just straight down.
When it starts to blow oil it just drops out and straight down.
Oily road.
Go downhill and empty the sump.
New rings every 30000?

Hi Hagar
The engine number on this motor is 9m/u/h/

Have had a few thoughts on this motor. So here is a therory but just that a therory.
During the late 1950's and early 1960's John Cooper used the "A" Series engine in their Cooper Climax Formula Junior Cars ( under 1000cc's).
These engines were dry sumped and had a scavenger pump fitted driven off the camshaft.
I was fortunate to purchase one of these " works" camshafts back in 1960 when I owned and raced a 997cc Cooper Mini. The camshaft had two drive gears one for the distrubutor and one for the pump in line with the oil filter.
Then again I could be totally wrong.

That's the same as mine - 948cc High compression unit (not that I've ever seen a Low Compression one)

Short of whipping off the sump and having a poke around, I've no idea what the bump's for. My completely uneducated guess is that it's just a casting bump, possibly related to the earlier 803cc oil filter mounting, but with no internals behind it.

GR, have another reply for you
