Hello..long time since I've been here..I'm looking to do a freshen up and have 2 weird leaks to deter..one on top of the fuel pump around the exit flange,I have smelled the oil, I can't sense fuel in the oil,,but.??...can oil follow up the arm through the diaphrams...?, and the other, underneath cylinder 2 and 3 exhaust manifold port, the top side is dry no leaks...the plugs are burning well..I might see a faint oil burn in that exhuast pipe but it dissipates quickly like steam...I'm going to try to figure out how to get some pics on..
