weird oil leaking rear main seal or oil pan arch - maybe PCV valve

Nice ,you found it...Is it running,as you hoped?... When the heck,is your summer? (lol..)

yes it´s running better than expected, maybe the 3,91 rear end is a bit short now (had to play with the kick down adjustment to get it driveable on German streets, as it mostly resulted in uncontrolled wheel spin, when hitting the pedal at the wrong rpm/speed) but it makes a lot of fun compared to the money i´ve spended for the junkyard magnum engine

errr.. summer in Germany good question, indeed *lol had a lot of rainy and cold weather during my holidays, and now as i´m back to work for 2 weeks now... temperature is climbing to 90° F and maybe more on the weekend (which will be fine as there will be our anual CBQ on a camping site with a lot of nuts car guys - mostly mopar freaks)
