oil out the dipstick

Probably the motor isnt broken in yet. You do need to run a pcv on one cover and a breather on the other. For the mopar performance valve covers I found that the stock pcv grommet works fine for the knock out on one side and for the other a push in breather - I used a K&N with the corresponding grommet that fit the knock out in the cover.

A cylinder balance test might be useful as well if you know someone who has it. It cancels the firing of one cylinder at a time and you read the rpm drop. What you are looking for is an even amount of rpm drop on each cylinder.
