I was priming my new build engine today (on the stand with the valve covers on to avoid a mess) and when I first started priming it I was only getting oil on the passenger side (running down the block on the inside). I don't have any help to run the drill while I turn the crank so I just started turning it in small increments and then ran the drill again. I eventually got oil on the driver side but only from all of the exhaust rocker arms, nothing from the intake rockers (at least not enough to flow running down the block). So I put it back at TDC and ran the drill again and like the first time there was oil flowing on the passenger side. However, what I didn't notice the first time was the oil was only coming out of the exhaust rockers just like on the driver side. Is this normal?
