Couple years ago i bought a L781 w/rod through block 3-cyl air cooled Deutz. Picked up a used one from a dismantler/rebuilder. Had pick of several. Used from a fleet of air compressors. So when faced with multiple choices of palletized used engines with ? hr.s cant hear run and all look to be the same. I went through them all and checked; oil, dirt in cooling fins ( figured if dirty probly ran hot), borrowed a wrench and gave each one a complete turn also trying to check for excessive free-play and exhaust manifold for oil or anything out of ordinary. The one i picked had no oil in the exhaust manifold. I changed over flywheel, oilpan ect.. filled it with Rotella 15-40 from sam's and now it slobbers oil from the exhaust. its dripping all over the place. runs good otherwise plenty of power, not missing, seems worse after idle. originally seemed like just one cyl doing it. I guess it could be just wore-out but it starts good and runs clean at first until oil show starts. it also will run on the oil intermittently, the diesel rattle will increase, rev up slightly and blow a large quantity of smoke. Any ideas ? Thanks.
