Unfixable Oil Leak
It seems that I am going go have to resign to the fact that this is going to be an issue. I don't know why it is leaking from the rear of the engine. Sealed it twice already. Replaced the turbo pedestal but I still see leaks.
First time, I had it sealed, it seemed to stop for a while but it came back. This time we found it in the EBPV and used the kit to fix it. Again it is back so we replaced the pedestal last night. Cleaned off all the oil and it leaks again. This time we fixed the mating surfaces with anerobic sealant.
Anyone have any words of wisdom?

Don't think so. It was an anaerobic sealant since it was to be in an area where there was no air once the turbo got mounted to the pedestal. Also used it between he pedestal and block.

THAT should have fixed it! Did you allow enough time for the sealant to set up before starting the engine? If it was still liquid, there's a possibility that it was forced out by oil pressure.
That's a great idea, using an anaerobic sealant! BSA and Triumph should have used it on their case halves in the '60's! It would have solved a lot of their oil-leaking problems. ;-))
I notice that Ford is now using this on the HPOP plugs in addition to o-rings, too. Loctite 680, which is a retaining compound as I recall, which is a little out of it's intended usage, but should work.
What specific product did you use on the pedestal?
Of course, your leak may be completely elsewhere, too.

New O-rings, new pedestal. EBPV not leaking. Just seems like it is coming from the back again.

Those are fine. We dyed the motor and it seems to be leaking from the turbo pedestal area. Why the new pedestal doesn't fix it, we don't know. Mechanic has exhausted all he knows and is having me take it to the heavy truck shop where they fix these things all the time. Just hoping to get more things for them to look at.

Pop, I am not sure but I believe it was a loctite product. This was done at a Ford Shop after hours. I do know it was red. The mechanic said he had used it for many other applications.

Yes, I need to remember that. Near future, I need to fix the leaks on the up-pipes, pedistal o-rings. Up-pipe has some soot build up on drivers side so I figure it's leakin' . Gonna do it all at once,may run in to something else while I'm in there. Did'nt realize that about rtv not sticking to aluminum.
