Oil all over the back of my truck.....or is it?

Hi guys,
My truck is having issues. I either have an oil leak or a problem with unburnt fuel (or both).
It is an 02 7.3
226k miles
ALL STOCK

I am 99% sure that I do have a fairly major valve cover leak which I will be checking/fixing this week (oil looks to be running down the head and block from above).
But I do seem to have an excessive amount of either oil or fuel (can't smell it) on the tail gate and raer bumper of the truck.
If am very concerend about pic #3 the end of the exhuast is pretty wet....What would cause that?

Any help would be greatly appreciated.







There are also spots inside the RH rear wheel arch.....can't be from the exhaust...surely...

You might have a HPOP o ring leaking. I had oil that looked just like that when one of my o rings blew.

The oil on the pipe is kinda weird, but check in the valley of the engine for a ton of oil. There are about 3 places it could be leaking from. Does any of it smell like fuel?

No, there is no fuel smell.
About 6 months ago I replaced the the o-rings on the back of the fuel heater.

I put a pan under it last night (RH rear of engine) and it has oil in it this morning....so I definately have a leak. But that doesn't exlain the exhaust tip.

Mate, I am hopeing it is something like that but it would be weird to only be at the tip of the pipe.
To me it looks like it is coming out of the pipe on to the bumper (but I am hopeing that I am wrong).

maybe its oil coming from inside the turbo and the pedistal o rings are shot too? Can you pull off a CAC tube and check for a ton of oil in the intercooler?

i have been looking at the pic and i agree... it looks like its commin out of the pipe.... like Dan said... check the turbo for a blown seal esp on the exhaust side. pull the intake tube and check for excessive shaft play, and/or binding of the wheel on the housing
