Two thing's come to mind any chance the 1/4- 20 1st back and the 5/16 -18 on the end of the pan ,,coulld be backing off squirting out and up into the air passing thru the bottom,, of the airstreme near the block and up to the head and pooling till there is enough gravity to pull it back down making it apear to come from the head??????only while moving??? loc titite and or thread sealnt might be applied ,,,SECOND, also if those two plugs are from #1 and 3
and are oil fouling is what you suspect it could be coming thru the valve intake /exhaust seals O RINGS leaking and weting the thread's to the header bolts at the back of the headers on at least #1 and #3 cylnder,,,also re added in the light of another post problem was the oil leak acellerated by poor engine positive crankcase ventelation hose colapsing, bad pcv valve or lack of the vacumn at all,,forcing the oil to push out any where it can find the least resistance crank seals, valve guide's, pan flange/ timing cover' ,just a guess ,,,,MIKE,, THE REST OF THE PICTURE IS BREATHTAKING ART WORK ALL OF THE BLUE OF COURSE,,, NICE PAINT SCHEME CAN NOT WAIT TO SEE THE REST OF IT SOME DAY,,,,
