I have only had 2 Hemis and both sucked oil through the intake gaskets. Never had that problem on any of my wedges. I have fought it and fought it on both Hemis. On the first one, I slowed it down a bit but never got it stopped.

Paper gaskets will let oil wix through them. The Superformance gaskets helped mine a lot.

On my current one (World block, MP Eddy heads) I think I have it slowed to a crawl. Haven't added oil for about 600 miles. But I do notice blue puffs at cold start-up.

Check your intake ports in the heads for oil.
