99 & up 7.3L Power Stroke Engine and DrivetrainDiscussion of the 99 & up 7.3L Power Stroke diesel engine and drivetrain in the 1999-Up Super Duty trucks and Excursions. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 7.3L Power Stroke engine.
Have an oil leak. Pool of oil in valley. About a 3 or 4 in puddle under truck each day dripping off driver side rear corner of oil pan, but only when running. Figured it was was running down back of engine from valley drain hole and sure enough, mechanic dyed the oil and its coming out of pedestal/turbo union. My problem though, I that mechanic immediately recommended new turbo and pedestal because he thinks their both cracked, even though he says he can't see any cracks. "We'd be lucky to ever actually find the crack," he says. $1500 job including materials for replacement with used pedestal and turbo. I think thats a bunch of bull. What do you guy think. I say just pull the turbo and replace the o-rings. What do y'all say?
It's a '99 F450 with 7.3 power stroke. Ebpv has not been blocked to my knowledge.
I'd Pull and replace the Ped with a non EBV one...it could be the o rings or it could be the actuaitor.
I've never heard of a cracked one..

I would try replacing the O-rings first. While you have the turbo off...inspect it really good. If the EBPV is leaking I personally would replace the pedestal with a non-EBPV pedestal and add the high flow outlet while you were at it. Just my two cents.
So what does the exhaust back pressure valve actually do? Help with braking or acceleration under load? Why would I want it? I live in TN.
It is used to warm the truck up faster when it is cold out. I doubt it gets that cold in TN. that you would need one. They can be converted to use as a exhaust brake so that might be a reason to leave it in.

That's what I told mechanic. He gave me some pushback and said they just crack when they're that old. I didn't mention it has 200k on it. He says he'll just replace the o-rings, but he didn't seem happy about it. I wonder what he comes back with. I'm starting to smell a rat.
How cold does it have to get before the valve opens?
Activates with outside temps at around 40F. Then the valve CLOSES under certain circumstances, like cold oil and certain rpm/accelerator pedal conditions. If you hammer the go-pedal, it will reopen and the truck will take off.

That's just BS. There's nothing that would cause them to crack. They don't move, and don't really get that hot. I'd almost guarantee that it's just o-rings possibly caused by a bit of vibration that may have loosened the bolts. Maybe you could look for a new rat ... err ... mechanic.
I had some issues where the o-rings would leak, even with new o-rings installed. The solution was to true up the mating surfaces by using a flatplate with some 400gr paper on it. A quick drag over the paper will indicate high spots, which mine showed the majority of the perimeter.

Great advice, guys. Much appreciated. Has anyone ever suspected a mechanic telling you an very expensive part is bad? If you think about it, a mechanic could have a parts truck laying around and knows he could sell you one of of it for 500% while still seeming to give you "a good deal" compared with new. Also, he could be looking for a good turbo for his own ride, instead of junking it after he removes it. Basically makes me pay for his turbo re
Also, it regularly drops below 30 in winter here, so it's a tossup about replacing ebpv. If I can get by without the extra headache of waiting for the non-ebpv pedestal to come in while my work truck is down, I'll go with just o-rings if ebpv isn't leaking.

I agree...in fact I wouldn't let this mechanic change the o-rings. Lack of trust...he is trying to sell you parts you might not even need and to prove it...well you get the idea.
and that right ther is why truckers have unions and , stick together better than any other group of blue collars . . . and why this site and others like it are so important to us . . . it mite sound corney , but needed to be said . hope its not too political for the sensors / admin. , but im not trying to start no trouble . its just upsetting when you follow the rules , try to put in an honest days work , and someone tries to get ahead at your expense . is it really that bad out there that shops need to do that to suckseed

Hate to say it, but in the current economic state of our country this type of behavior is getting more and more prevalent. I have worked " on the side" for just about 40 yrs now and I see more and more customers bring huge estimates from dealers and independent Shops alike when it only needs a minor fix that takes me less than an hour.
