Oil leak questions

So i just intalled a MBRP 5inch exhaust in the process i noticed

1. Standing oil in the valley beneath the turbo

2. oil trail of wet oil down the back passenger side of the motor covering the majority of the starter.

3. Possible oil in the exhaust side of the turbo (my buddy stuck his finger on it but couldnt say for sure)

4. Possible oil coming from the tail pipe, I'm not sure if its just soot the has caught some condensation.

Someone told me that the bearings might be going on the turbo?


My buddy has told me that the oil leak in the valley is very common ...this is my 3rd powerstroke but i never really did much to my previous PS so idk about this particularly.

I tried using the search tool but "oil leaks" "exhaust" and "turbo" make up 99% of this forum


my mods are in my sig

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'd get the top end fixed before I went any further.

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
