Oil leak 14 liter Detroit 60 series

I would check the oil feed line coming from the block to your fuel pump. It should be a stainless line with a brass fitting that will sometimes back out.

 

The only thing I would be concerned with is if the oil is blowing out of turbo, through ata into intake. Pull the hose from turbo, check for oil. Otherwise whatever it is, it’s probably a minor, hose connection, as mentioned, or a sensor leaking from somewhere, maybe valve cover on the very front side, or more likely at the corner, its most likely coming from a forward source, blowing back along the manifold.

 

More than likely you’ve got more than 1 leak, Front cover or compressor oil supply hose/ fitting upfront, and sensors up above starter or rear structure ( bell housing to block) , on rear, Unless last turbo blew, or was leaking, pushing oil, into air to air cooler, and ata wasn’t boiled out ( cleaned) and oil is getting pushed through it now by new turbo. Excessive idle, especially low idling, will cause everything to seep oil. Low idling will also destroy turbo bearing, seal will leak oil into ata.

 

When the last one blew, did it push oil into cac? Or just pipe? Did they boil cac? Or did you replace it? Or was it OK and reused? So this BG is the 2nd replacement, after the first one blew? Too much of a coincidence. I wish I knew more, someone will have some ideas for you I’m sure. Id guess the cac needs a good cleaning now.

 

Do you let the truck idle for a good 5 minutes with the engine fan going before you shut it off? All that heat and dry spin from shutting it off right away will kill a turbo pretty quick.
