We have a problem with one diesel generator , it shows very high lube oil consumption, you can't keep running the engine without add constantly lube oil to sump tank
The following items have been checked:
- Exhust gas is normal
-There is not pressuraized crankcase
-Oil coiler hydro tested satisfactory
-Oil seal (crankshaft) is ok
-No cracks at the sump case
-Turbo chargers ok
Please provide a technical advise , what we should check further !

When you say "very high" how about a number like in gallons or liters per hour?
Oil has to go somewhere, so you're sure it's not going out the stack or the breather? It's not going into the coolant?
How many hours on the engine since overhaul or any major service?
Do you have another generator of the same type? What is it's consumption?
When did the problem start to occur? Has long has been happening? Getting worse or staying the same?

Thank you for the feed back

The rear crankshaft seal and wear sleeve need to be replaced
Once again thank you so much for your attention
