Do LB7 have head gasket issues?

Why is diesel fuel getting into my engine oil?
Some engines may have a crack in their cylinder head which could cause this same problem. But I do not think it is the case with your Caterpillar engine. Please keep in mind that diesel fuel in the crankcase drastically impacts the oil’s lubricity and creates excessive wear in all parts and the turbo bearing.
How can I tell if diesel fuel is getting into my engine?
I would take an oil sample with the contaminated oil and send it to a lab. They will tell you what you already know, that there is fuel in the oil. But what you need to determine is if there are any high levels of any engine bearing material in the oil. That will allow you to judge if there is any real damage that has occurred to the engine.
Can a Caterpillar engine leak diesel into the oil?
I have searched the Internet regarding the problem and it seems that this particular Caterpillar engine has an injector seal that can leak. When that seal leaks, diesel gets into the oil. Do you know anything about this problem?
