Today I worked on the B7100, and buggered it up more than fixed it. I have developed a considerable oil leak at the front of the engine, and began looking into that. In the process, I noticed one of the new injectors was leaking slightly. In addressing the injector leak, I snapped the bypass line on the front injector. I was able to solder it back together, but I don't think that will last. I have been reading older threads on oil leaks on front of engine, and trying to determine how much more I want to put into this old girl. I have grown fond of her, but the new L2501 will be delivered before too long, and this just keeps costing me more money. Not sure when to pull the plug and call it quits.
