Before you go digging for a turbo leak - how much oil are you losing between changes? If its less than a quart - I wouldn't even bother. Oil in the valley can't come from the turbo internals, so you may want to look for that leak first. Clean the valley to within an inch of its life, and then monitor where the new oil shows up. If its in the back, it could be the turbo pedestal o-rings. Mid section look for HPOP oil lines or an oil rail plug. Up front, look for HPOP o-rings.

No matter where on the top end it leaks from, everything in the valley runs back and out the drain hole in the back passenger side of the motor and down the back.

I just went through a turbo pedistal leak. Good advise on above posts. I cleaned mine up & parked truck facing the sun. Then I crawled up on passenger side battery after engine had run for 10 minutes. I looked below the turbo & walaa! I could see the oil literally pumping down the side of the pedistal. All of the oil went into the valley, out the weep hole & down on my starter. Went to ford, got the O-rings for 21 bucks, including the three inch oring on the front of the turbo, & slapped em in. Good luck. I suggest you find the leak, cause stealerships are know for mis-diagnosing oil leaks & replacing extra crap that wasn't in fact leaking. BGJ
