engine oil leak questions....

[71biggreenk10]

So, the rocker came in....and it went in rather easily. I did a full running lash of all the rockers, just to be safe, because when I took the valve cover off the first time several of them were loose. I was skeptic to believe that an intake valve not opening could cause an excess of oil build up in the cylinder, but I ran the truck for about 20 minutes, and took a drive about 3-4 miles and there was no more smoke pouring out of the tail pipe. Thank you guys for your help.
