On a side note.  Where can one source a pack of these huge honking oil drain plug gaskets?  This brass one has long since passed its days.
Every time I got to the parts store all they have is the wee one's for a car plug.

You need to discover why the crankcase is pressurized, whether improper ventilation or blow-by.

Have you read the plugs?

Valve stem seals are new.  Passages are clear.  Smokes at acceleration.  But not every time.

You stated that you removed the pcv and ran a draft hose.   Did you watch the end of the hose to see how much smoke comes out of the hose?   Usually smoke after you decelerate is an indication of bad valve stem seals.  You could also have bad valve guides.   Have you had valve covers off and check to make sure oil drains for the heads are clear?

The vacuum source on the ECZ-B intake does draw from four runners, 7-8 and 3-4 but the main draw will be 7 and 8 runners because of it's (vacuum boss) positioning on 7-8 runners. It is not meant for a PCV vacuum source as the engine crankcase fumes will overload those cylinders and not be distributed equally among all cylinders.

Also, any oil leak (gasket/seal) in the engine assy will not only leak oil but will lessen the affect of the PCV System as the internal vacuum draw will be lessened through the valve/system with outside air and also possibly disturbing fuel mixture ratio.

Just for discussion, describing Mummert's Valley covers as "bling" is pushing it. Quite often original valley covers from engines that were out of chassis or say from a salvage yard have distorted or damaged valley covers that may not seal properly.  But, more importantly the rear vented model is designed to replace the side of block canister unit & permit use of a rear crankcase draft tube or better yet a baffled PVC setup..  That's hardly bling!

Skyhunter: Don't know if this helps at all, but, your statement that " the rear of the manifold only appears to feed from two cylinders, is incorrect. That orfice should split inside & feed from 4 cylinders.. As others have indicated you may have a defective PCV valve & or a serious problem with engine internals. Need to check out those possbilities.
