Can anyone suggest reason for oil leak drop by drop from the joint gasket of turbocharger and exhaust turbine of a Cummins DG.

This leak is not there when ran on no load and observed only when DG is loaded to50% and above.

Thank you.

Excessive crankcase pressure is the most likely cause.

Using wrong oil could also be a cause.

The link that SE provided give a very logical and simple way to diagnose this problem.

Good Answer SE.!
