New stroker motor and ever since I have had a pretty big leak dripping off the passenger side header flange which then drips on to the header and all over the starter. You can clearly see wet oil on the bottom of the header flange right by the middle cylinder. The valve cover is bone dry all the way around. The car does not smoke under boost and the oil is clean, however it does have intermittent blue smoke from exhaust at idle which I attributed to a bad turbo seal. Breather at front of valve cover is also dry. Could the head gasket be leaking oil? Car runs great, no smoke under boost. Coolant is also clean.
