Engine Breathing

Hi, I am just about to get my MM running and seem to remember that the engine wasn't totally oiltight (front/rear crank) and it will probably be worse once it is running! I wondered if anybody has experimented with negative crankcase pressure by feeding the breather pipe to the inlet manifold? It seems to me that a bit of negative pressure might help keep the oil in? Any thoughts?

It is called chassis lubrication, an effective rust preventer. They usually drip a bit, just cover the drips on the garage floor with 'Kitty Litter'

Additional thought.
If you feed a breather straight into the inlet manifold without some kind of filter you may find the car blowing out clouds of exhaust smoke. I know, I tried it with a 1275 A Series. The neighbours thought the garage was on fire!

I suppose the thing to do is to try and remove the gases from the sump without the oil. Which I am sure is easier said than done!
