Regarding the injection timing , no I didn't set the throttle to full load . I think I will try the bubble method next though . Re the front seal , I did mark the balancer and crank and in installing the seal, the bugger deformed so badly going over the spacer that I have to get in a new seal . Here in the Fraser Valley a Mercedes is a foreign creature and it usually takes a day to get a part in . I have ordered a new spacer so I can slide the greased up seal over the spare spacer first then slide the spacer onto the crank to guide it . Unfortunately today is my Monday and , as I work 10 hr shifts with a 2/12 hr commute daily , I don't accomplish much until my days off .
Thankyou for all of your help . My beloved spouse finds MB ownership takes me away from too many of my farm chores as well .
