@david mack Oil level is falling quick. Just refilled it a week ago, carefully exactly to top dipstickline and run the engine maybe 2 hours since then. Now its at the low dipstickline. I Tried to repalce some of the gaskets, but could not reach some, like the cylinderhead gaskets and beyond. So there is a Hose out the back for airintake, there was an electrical blower at some point, but not anymore. The outlet is big and effective, out of the engine room. The grid is rather dirty i reckon. Thanks!! @ Mike Air leaking in could be it. I will check that. Fuelfilter is waterseperating, hadnt had any Water in there since months and chanched the filter last about 2 months ago. But this particular Problem began at a different time.

Hello, so i got this pretty well used engine in my boat and since about 2 months its doing following: It starts up fine(just handcranking, Starter is broke) but after a few seconds or sometimes minutes it just slowly looses its power and eventually dies. Some times it fires up again,and dies, some times it doesnt Start anymore. I even had blue smoke coming out of the oil cap of the rocker cover. Its not a New Problem and i did a lot of repair already to try to fix it. Injectors got tested and cleaned, fuel is flowing to the injectors (its running fine for a couple hours in between), fuel is clean. It is leaking a lot of oil, but all people i asked just say old Lister do that. But its leaking a lot, our bilge is a real Bad oil sump. Its as well leaking fuel on the lines on the engine itself. I need more ideas where to look or repair, thanks a lot!
