Weeping 203

Howdy folks, im mike and i guess ill jump right in. Got a 203 a week or two ago and it's starting to weep oil around the backside of the rocker covers / valve cover and oil pan.

Is this a common 203 occurrence and is there somewhere that I should look first? Is this something that can be remedied by re-torquing the valve cover and oil pan bolts?

Dream sequence Afterthought - [Maby increased crank case pressure?]

I almost want to say that the shady roadside dealership I bought it from used the wrong Walmart oil when they did their half-assed courtesy service. And that's call it causing the system-wide oil "weep".

Could be expansion plug or crankcase ventilation cover if it's on the passenger side. Both were an issue on mine and dripped oil on to the exhaust to create a bad smell in the cabin. Both are common problems.
