6.7 bottom of engine covered in diesel.

[ToddP]

My ‘16 6.7 is leaking diesel somewhere. The bottom side of the engine is completely covered in diesel/oil, it smells like diesel but looks engine oil caked all over. I have noticed it has spread underneath more lately. I check the fuel filter on top on the engine and it’s fine. You cannot see anything dripping while idling so maybe I have a high pressure leak?
Any thoughts on where to start?

No clue. Is it already out of warranty? Engine is covered to 100k.

The truck has been running hot since 45k miles.

First thing i would do is take a look at it.

Some dealers don’t care. Mine doesn’t and it’s worth looking into. Had a Dodge that was dereted since it was new and had warranty work done on it as well.

I took it to a buddy’s shop and the mechanic said I blew a seal out on top of the engine. I’m not sure which one I did not get to speak to the mechanic personally. I was told it was a 36 dollar part but the had to drop the transmission. I did not have to pay labor (18hrs). I was told I need a better crank case vent system. I was told the hot tune I’m running cases too much pressure build up in the crank case.

What is the best crank case vent to buy? Or which direction do I need to go?
