major oil leak, need help Options

[ericoneal]

I finished my pushrod tube seals last night and prepared for a short "shakedown" run this afternoon. Checked oil while cold, and it was at first level mark. Added .5 quart which took it to just above full while cold (odd).
Now this: Attached is a silver box located on my fire wall, used for crankcase pressure. I think its there from when the car was carbed, but the PO had installed Megasquirt FI, but there are still three hoses running to this. It has always been 'oily' but never really leaked. I checked the hoses and wiped it off. They seemed tight. Again, never any real problems from here, so I thought all was good.
After a few miles of spirited driving, I get home and saw the attached. Oil everywhere, pooled on engine, splattered on firewall, etc. Pretty sure it is all comgin from here.
My question is, if the hoses are indeed tight (i did not touch them), what would cause this? Pressure overload from the crankcase? Too much oil?

IM at a loss.

Yup, same here. I seem to get a different reading everytime I check.
I drained all of the oil overnight last night, then refilled with EXACTLY 3.2 quarts (no filter change) and the dipstick says I am .5 quarts over.

Good news is that I took her out for a short spin and no exploding breather box and all pushrod tubes are sealed except one. The only one that didnt "pop" as I put it back. Gonna try to get back in there and remove and replace to see if that fixes it. Probably the first time in 40 years that my car has only dripped one drop of oil after a drive.
