If there is oil in the rear air filter then your rocker assy is worn =
out. Warm up the engine, then remove the valve cover and start it up. =
Almost no oil should come out the top of the rockers. Yours probably =
will squirt a lot of oil out of the rear rockers. This will then be =
confined to the inside of the valve cover. Then the breather will suck =
the oil into the rear filter and your new engine will burn oil just like =
it did before the rebuild.

We see this all the time and have rebuilt rocker assys in stock

Unless the rocker shaft is worn, oil should just barely seep out around =
the rockers. It would be really hard to get to the vent tube.  With a =
worn rocker shaft, oil could squirt high enough to get into the tube, =
but I think you'd see blue smoke. =20

If you're not seeing blue smoke, I think I'd be looking for leaks.
