Is this possible ???
So for the past few days I have been installing bellowed up-pipes . I had the turbo off and the pedestal off to do the install . I had a very small oil leak at the back of the motor that would run down and drip out the torque converter inspection plate . I figured when i replaced the o-rings under the pedestal and the o-rings under the turbo , the leak would stop .
Now I have it all put back together but still have an oil leak except now it is a bigger leak .
Is it possible that once the o-rings go through a heat cycle , that the o-rings would expand and stop leaking ????
I'm asking because when I took my truck out for a test drive , it was leaking pretty bad but when I got back home and shut it down and took off the CAC pipes to get a better look , I fired the truck back up and it didn't seem to leak hardly any more .
Even when reving the engine at 2000 rpm for 30 seconds .
Anybody else had the same situation happen with their truck when replacing the o-rings with the turbo or pedestal ??
Any thoughts or suggestions ?? Thank-you .

I had a pretty decent leak from my pedestal o rings. Enough to leave a couple lakes of oil in the valley. Got some new ones from dieselorings.com.
Fixed the leak right up for about three weeks. Now I have a slow drop... few drops worth over night, but no lake in the valley.
Sort of annoying. I am positive I seated the o rings correctly, so I am wondering if the leak is coming from somewhere else.
I know for damn sure a few drops of oil isn't worth the misery of pulling the turbo again.

I had the same annoying leak as you 90pioneer . I figured it would stop when I put new o-rings in from Bob @ Dieselorings too . I'm going to drive to work today and see what happens . I'm figuring that I'm going to have to get the turbo back out and check to see where the leak is and that that I haven't dis-figured the new rings . What a pain in the a$$ when having to put that marmon clamp back on the back of the turbo .

I was hoping it was as simple as seeing a leak at the HPX . So I checked to see if my HPX was causing the leak but after I wiped it down , I couldn't see any trace of oil at the HPX connectors .

What ft/lbs did you torque the pedestal to? I did mine two years ago and the Ford book says 18 ft/lbs...Bob at Diesel Orings says the Garrett manual (who makes the turbo and pedestal) says 34-36 ft/lbs. I torqued mine to 34.
Now I still had a small leak which I traced to saturated intake boots. Installed new boots and Riff Raffs inserts and I am dry as a bone for two years.

I know I torqued the turbo down to 36 ft/lbs . Crap , I don't remeber torqueing down the pedestal . I guess i had better figure out a way to get in there and check . I had already had the inserts installed in the plenums BUT I did install new boots and clamps from RiffRaff so I don't believe there to be any issue there .
My leak is definately with the turbo or the pedestal . There is no oil in the valley . Just running down the back of the motor .

i meant turbo to pedestal at 34-36......don't go higher than 18 on the pedestal to block. I was convinced mine was leaking but it was the intake boots all along.....

I second spongecop. When I put the WW2 in I did not torque the turbo back onto the pedestal enough and it caused a leak. I would try that before dismantling it all again....like you said the marmon clamp is a huge pain.

My HPx was running down the FPx that I put black electrical wrap on so I didn't see mine at first. It looked like the pedestal but it wasn't on mine. If torq'd they shouldn't leak. Check it and if not you mitt have to change the O-rings.

UPDATE :
I took my truck apart again to torque the pedestal down to 18ft/lbs . I swapped the o-rings that I got from Bob @ Diesel O-Rings ,from under the turbo with the ones from under the pedestal , hoping that it would stop leaking . Well it did slow down alot but still leaked .
I was frustrated and dissapointed with it still leaking
. I decided to take it to Diesel Doctor here where I live so he could try his luck with it .
He replaced the o-rings with OEM o-rings . He said he used di-electric grease on the o-rings when re-assembling to keep the o-rings in place . He commented on the fact that it wasn't leaking to much and that I wanted it fixed as most guys will just live with the small leak . He put it back together and now it's not leaking . He charged me $380.00 cash out the door , $20.00 for o-rings and the rest for labour .
It turned out to be more expensive that I had hoped it would be but all in all , it was worth having the bellowed up-pipes in my truck .
Thank-you gentlemen for your thoughts and ideas .

After I did my Pedestal O rings, I thought it got worse. So I went to my local dealer and Rich gave me 2 bottles of dye to trace the leak. Then I shot degreaser in several areas and hosed that off.
Ever since, NO leaks. I think it may have been residual oil. Didn't take it back to Ford to analyze where the leak was.
It went away. Yay!!
