60KVA generator is drying engine oil. What can be the cause and what can we do?

Check the gaskets are fitted correctly and there are no warps on surfaces.

defective gauge or wiring./defective thermostat??/ damages ; if the motor got hot enough to melt oil cap and distributor cap , you can bet the head gasket is gone/warped head just to start with, may even have collapsed oil and compression rings/stuck lifters,really gotta love this car to put the bucks in that it will take to fix .... good luck!!!

Any engine that burns oil should be given a compression check and then have the compression rings replaced if they leak.

Why would you be doing this??

Has the motorcycle been sitting unused for a long time, has something caused raw fuel to enter the combustion chamber or is it possible otherwise that the cylinder walls are dry and bare??? If so you might be wise to squirt an ounce or two of light oil, preferably 2 stroke oil into the cylinder before turning it over and starting it BUT not too much of any kind of oil as too much will burn, leave carbon and cause compression rings to stick etc., Two stroke oil is designed to burn above piston compression rings and not cause this problem but an excessive amount of this oil would not be good either. If the engine has just been rebuilt the rings should also not have been soaked in too much oil for the same reasons. if the engine was rebuilt with new piston(s) and/or rings and it was put together completely dry and oil free you would need to provide some oiling via the combustion chamber if you were not going to disassemble the engine and properly lightly oil the piston(s) and rings and reassemble the engine as would be the best and appropriate thing to do in such circumstances. If the engine does not have some need to have extra lubrication because its cylinder walls are somehow dry and oil film free then there should be no need to add oil to the combustion chamber prior to staring and running it.

It is suggested you to run your Deutz diesel generator according to users' manual, thus, it can help prolong the service life longer and less problems occur during the use of the generator. About Deutz diesel generator operation requirements and procedures, please refer the following article: https://www.dieselgeneratortech.com/diesel-engines/Deutz-Engine-Operating-Requirement-and-Procedures.html

The injectors probably were damaged because the unti ran away, it should have shut down on over speed. If it did not then the sensor and control need checking. I would also check the engine oil to see if diesel has found its way into the sump. If it has then the rings are shot and the unit is "self feeding" off it's own engine oil, and no control signal will shut it down, it needs checking out by a pro, as a runanway diesel is extrememly dangerous in the size you are speaking !

Could be leaking from valve cover , or valves are not seated right. Though the piston rings . Or the seals on the valves are bad ( think there called o rings)

4.0L
The Camshaft Position Sensor (CMP) on the 4.0L 6cylinder engine is bolted to the top of the oil pump drive shaft assembly. The sensor and drive shaft assembly is located on the right side of the engine near the oil filter.
The CMP sensor contains a Hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the oil pump drive shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts.
When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts

Reseal the valve cover. Don't use a gasket, use RTV sealer for the best results.

Make sure that the throttle linkage is all there and not damaged/misadjusted, then get a manometer and check your inlet gas pressure. Gas pressure should be 8 inches of water column and stay there running or not.
