MG Midget and Sprite Technical - Oil catch tank

I have a 64 MK1 midget with a 1098 and a DCOE 40 Weber. Since there is no vacuum port on the intake manifold, I have been looking at stainless and aluminum catch tanks. Is there any reason I should have a vented tank over a ventless one? Should I look for one with two ports rather than one and try to run a vent hose from the fuel pump blanking plate (a PO has upgraded my engine to an electric fuel pump) or is the timing chain cover vent enough?

I also wanted to say that for the last two years I have been reading these threads and feel like I have earned a degree in Spriget from all of you. It has been both enlightening and entertaining, and after reading many of Prop's threads, I don't feel shy about asking questions.

Are you sure it's a 1098? 1098s have a breather on the tappet chest cover, whereas 1275s have a breather on the timing cover. You could, of course, have a 1275 timing cover, but you should still have a breather on the tappet chest cover, unless it has been swapped for a plain one.

My mistake. It is the tappet chest cover. It is a 10CG and according to Horler's book it is from Fall of 63 while the chassis is from January of 64.

If the catch tank is NOT vented how does the engine breathe?

Duh. When you put it that way it seems so simple. Thanks.
