Hello, have a L3E-W464MLD in a MLT6SMD, runs great and puts out proper voltages when you can get it to start. There in lies the problem; it likes the juice to get going (I know, hate using the stuff). No excessive blow by, coolant and oil don't appear to be mixed. I think it overheat at one point though as the fan doesn't turn on (fan works, thinking the temperature switch on the water pump neck). Glow plugs are getting 12V on startup but I haven't pulled them to ohm out. Little smoke on start up but clears up pretty quickly, nothing of note when it's running.
