Hello All,
I replaced the engine in my E38 with a used 5432 this winter and although the "new" engine runs great there is one small problem. It starts instantly when cold, or even hot if I just shutdown and restart in a few minutes. If I go for a 2-4 hour sail and then try to start the engine to motor back into the harbor it doesn't want to stay running. It will almost catch, as if running on two cylinders, but not quite, and die 2-4 times before it will stay running. Once running, its fine and seems completely normal, but it takes a few seconds to clear out from the attempted starts.
-Fuel filters are clean, and new.
-Plenty of fuel
-New fuel tank 4 years ago.
-Electric fuel pump, new, functioning perfectly
I have tried starting with and without glowplugs, with and without fuel pump, etc. Nothing seems to make a difference. More annoying is that once I have returned to the dock and shutdown for 15-20 minutes it will restart instantly. I cannot duplicate the issue without a long shutdown period.
The engine does not smoke, make any strange noises, etc. I have a decent amount of experience with diesels but I can't figure this one out. The next step is to start swapping parts like injectors, delivery valves, etc.
Any ideas would be appreciated, TIA, RT
