possible oil leak culprit

So with the turbo off I was cleaning the valley and took the cross over oil line off, i noticed it was wet around the head and took the fitting off and found this.
this is the drivers side

this is the passenger side

O-ring looks in much better shape. Oil is on the drivers side of the block, not much in the valley. Oil cooler is dry in the back so Im thinking this little o-ring could be the problem?

Re: possible oil leak culprit

Those O-rings aren't just any old o-rings, they need to hold up to 3000+psi at like 450degrees. Go to you local parts store and ask for high temp o-rings, they'll be much stiffer/beefier.

You can buy those o-rings from ford, I think they are about 2 or 3 bucks a pop. Or you can order them from Guzzle

Re: possible oil leak culprit

yeah, pink...orange...doesn't matter, you'll be able to tell the difference in how the feel from a normal oring. these ones are not nearly as elastic, feel a whole lot stiffer.

Re: possible oil leak culprit

So I out new rings on and it was like a new truck, but it started the poor idle again and sure enough the drivers side o ring was torn. I lubed the hell out of it when I put it in but it looks like it shaved the o ring when it got tightened down. I see or feel no burrs in the hole, any ideas?

Re: possible oil leak culprit

What did you torque it to? I believe the torque spec is 16-18 lbs-ft for those plugs...
