Oil leak
Well hear I am again fix one problem now I got another problem last time it was fuel now it's oil so what I got goin on is a oil leak that looks like it's coming from on top the motor on the back I first discovered this nice surprise when I went into the store and came back out and seen two 8 inch round puddles of oil laying on both sides of the motor like I said at the back I thought oh **** rear main seal but upon further inspection it's coming from somewhere on top and rolling down both sides of the motor looks like near the turbo what could this be possibly a line or a check velve or seal or o ring on the turbo? Is there a common thing to go bad on these trucks to cause a leak in that area? Thanks in advance.

Could be the turbo oil drain. If I remember correctly, it is a tube under the turbo that returns the oil to the motor. I believe it has one or two o ring seals. It would show up as a leak off the back of the engine.

Look straight down behind the oil filter. There's a gap between the rear of the oil cooler base plate and the turbo pedestal that crosses the entire block. If that metal isn't coated in oil, then it's something further back. It would be easier if you have am inspection camera, because it's very tight with a lot of junk in the way.

Hey guys I did some more digging around and I found my oil leak it's seaping out from the base of the oil filter housing what is involved in fixing this can I just change a gasket or do I have to change the whole housing? Thanks

If it just the tall cylinder section then yes just a bit O-ring.
The PITA part is you have to disconnect all the fuel lines so
that you can lift that section up and pull out the old seal.
Make sure that it's the lower seal and not the one for the cap.
The cap should get a new O-ring at each filter change.
Also a cracked cap can also be a leaker.
