96 oil leak.
 

Hey guys im newer to this fourm. I have a 96 f-250 7.3 turbo diesel 104k on the motor my problem is im leaking oil somewhere up top of the block. i HAVE checks the oild plugs on my heads they are not leaking. when i turn my chip up and get on it you can smell a little oil burning off my manifold. my engine valley has oil in it along with my heads and everywhere else underneath of it. it only leaks a little but its annoying any ideas?

check the plug on the back of the hpop i've seen it leak a few times, fixed a few of them by replacing the oring on the plug
