Had the oil changed on this truck for the first time since i 've had it. All of a sudden now i'm getting oil leaking above the fron diff. The breather tube doesnt have a cup on it so i assume thats where the oil is from, but this is a lot of oil and its blowing down the side of the truck to my fender. what can i do about it. never had the problem till my oil was changed

 

Check the oil level. It sounds like they probably just dumped in 12 quarts. 12 quarts would be fine if you could drain every ounce of oil in the engine. I start with 10 1/2 quarts and add if necessary. Overfilling will definitely cause it to blow out the breather tube.

 

Make sure it's oil not diesel.
When my CP3 began to leak I thought it was oil film...
engine block, drivers side, can't remember how that relates to front diff off the top of my head
