Oil in exhaust on e7 350


Stretched out
 Share

Recommended Posts

Started in on restoration of my 91 R yesterday. Got charge air cooler and exhaust unhooked from turbo and found oil on both sides of turbo. Going to take manifold off today to see what it looks like. Have no water in oil and no oil in water. So I don't believe it is the head. Do you guys have any suggestions, thanks

Both sides meaning what, there are 4 inlet/ outlets, intake air, charge air, exhaust inlet, exhaust outlet.

Sounds like your turbo is passing oil. Grab the propeller nut and check for up and down play.

What he said,sounds to me like spun turbo bearings.....

Lack of planning on your part does not constitute an emergency on my part....

the turbo can still be tight and push oil like glenn said plugged air filter will cause this .if you don't know the history of this truck I'd reassemble with old parts for now change air filter clean turbo and manifold and run truck under load and reinspect also check draft tube for excessive blow by. (You could change turbo if you have a good one before test running, seal maybe too damaged on old turbo to reseal) I'd hate to see ya rebuild the heads only to find out you needed a in frame

No oil on air intake side and air filter seems to be clean. I just bought the truck so I have no idea of the history of it. Pulled pan and appears to have bearing rolled in as they are stamped but that's all I really know about it. I thought about going ahead and pulling head off and doing inframe. Already have charge air cooler and radiator out of the truck.

I'm sending the inter cooler off as it has few spot where fins are shoved in. Likely will need replaced. Where is my best bet to get an in frame kit and reman heads. Waiting for price from Mack but didn't know if there is better place or not. Also I read on here before that an e9 turbo will work on an e6. Will it also work for e7 or is it that even recommended. Not worried about getting more power out of it. But figured I would check into it if it doable while it's all tore apart

the wet draft tube is normal if you can use it for a leaf blower that's not normal.... seen a few that would clean shop floor!

you could check pai or ipd for kit prices don't know who your local dealer is should be able to find on line
