Oil Leak

[kramdrof33]

Hello, everyone!
I recently bought a used 1996 F-350 w/ 7.3 TD.

Everything works well, except on the drivers side rear valve cover, there seems to be an oil leak (seep).

It covers the valve cover from about halfway back, and seems to be centered on the rectangular riser on the cover. (crankcase breather?)

What should I be looking for? The turbo is housing is clean except for the tube from the turbo to the cover.

I cannot find a good reference on the crankcase breather system, but I removed the oil filler cap and there does not seem to be excessive blow-by.

Thanks in advance for your help!!!

HPOP, EBP valve, and turbo pedistal O rings are the 3 most common oil leaks on a 7.3.

Maybe I am misunderstanding your post but to me it sounds like it is just oil that has been sucked up into the intake pipe and is leaking back down. When I bought mine and did the D.I.Y intake I was surprised at the amount of oil in the intake pipe which made a mess on all the boots of the turbo system and valve cover so I did the ccv mod. Here is a link to another post that talks about that mod.
7.3 crankcase breather mods
Oh and by the way
There is a lot of threads on the ccv mod if you do a search for them.

Thanks for the info....from what I am reading, as long as it is only minor, it is normal, and I will go with that. I am not planning on completing any mods until I know this truck is good to go. There is absolutely no drips from this leak, it is just enough to gather dust and dirt on the valve cover creating that sludgy muck on the top.
I was a heavy equipment / diesel mechanic, but I have not done that work for years....amazing how quickly we forget things that only yesterday were second nature.
Also, anyone know a GOOD 7.3 PSD manual? Direct from IHC? I have the truck manual, but it covers all engines.
I will keep digging on here for more info.
Thanks Again!!!
