I have an engine that I just rebuilt. It was bored over .020 head surfaced and o ringed and block surfaced. Engine has about 600 miles on it. Every time I run it hard it will pour oil out of the blow tube. It has jd's tappet cover on it and I orinally thought it was just because that wasn't baffled so I put a 90° elbow on it and a 180 fitting and it still did it. So I took a 45 off the 90 and ran it up over my brake booster then down and it still does it I was wondering if this is something common and need to just move the breather to the top of the valve cover or if there is maybe a piston ring issue. It starts right up so I don't think it would be that.
