Replaced the breather box and o-ring due to oil leaking from box. Now have very bad leak from cap even though the cap seal was also replaced. Any ideas?

Check all your vacuum lines, flame trap, and the entire PCV system.

you must remove the small rubber hose,from the back of the inlet manifold first,now remove the black rubber hose from the top of your breather box, over the top of your engine it goes over the camshaft cover,just pull this up to remove ,clean all of those hoses ,they will be blocked with carbon.

Did that after spotting the new leak. Any other ideas?

Make sure the nipple at the intake manifold is clear. If you sense pressure at the hose at the manifold, the system is not clear at that point, otherwise track the pressure back to its source.

... rather the system is clear to that point and there's no vacuum at the manifold tap.
If there is no pressure, work forward.

use an engine oil flush, to clean oil ways,drain and refill and change oil filter,what colour is your oil,is there smell of burning,take off the oil cap,look in,can you see black carbon on your cams in the cam cover,the flush will remove that,you may have blocked oil ways and dirty filter on the oil pump,so oil flush will remove that.
