no oil problem, help,

[BLue n white R1]

Ive done a few searches on the forum already, with no luck. How Do I check to ensure OIL is flowing in my motor, As i have someone crank Im looking inside the oil cap at the cam lobe and I dont see any oil. I just finied my sr install and dont want to kill anything.

If the cam lobe was silver, with no score or scratch marks, its ok.

well.. long story short.. I let this SR sit in a s13 for a year because I didnt register the car..and one day I descided to start the car, and when I did.. i didnt prime the oil pump.. and it started to screech, so I pulled the motor.. and found that the head cam bearing to be really badly err... yea the cam basically ate away at the cam bearing, so i picked up a used Head from a friend, from a good motor, and had it cleaned and redone, and reinstalled everyting including a new oil pump. I just want to ensure all is as it hsould be before I start it. any suggestions?
