oil leak

[mighty mouse]

I have a 2000 f-350 with the 7.3 superduty diesel engine. It has aprox 270,000 miles on it. I took it to my mechanic for a slight miss. I live in Michigan and it was a little cold but not bad. He let it sit in his driveway over night and when he started it the next day it smoked somethin bad and oil was coming out of the exhaust. This doesn't sound good he's thinkin rebuild engine. He say's he checked to see if the turbo was leaking and it's not. Any suggestions.

my first bet would still be turbo. sounds like a seal in the turbo might of let go..

thats pretty quick to jump to the rebuilding of the engine..........i agree with the statement above

Yeah check everything else before you do that.

I asked the mechnic how he checked the turbo and he said he took the filter off and checked the fan and if flowed freely and he didn't see any oil on the fan.
What would be the true way to check the turbo??

[Tony V]

I would say that was if the turbo was blown.. Have him check around the Pedistal... He may be wanting to make a quick buck off ya

[MrJohnWayne]

to fully check it you need to pull intake and exhaust. the seal on the compressor side could be fine, but the seal on the exhaust side could be bad. Won't tell from just checking compressor side....

This guy did rebuild the pedistal. I'm going over to watch him take the turbo off and then we should be able to tell.
I want to thank you guy's for all your input. It gives me some hope. I guess the rings could be bad but I just haven't heard of that happening on a diesel with 270,000 miles.
tanx again and I'll keep you posted,

All o Rings can go bad.

[mighty mouse]

Yes I understand that but he's talkin bout piston rings and I understand they go bad too... but ya don't hear bout that much from diesels. (And I know there's always exceptions and thangs).
