7.3 powerstroke oil leak

[trythis]

Found a puddle of oil under the passenger side dripping off the bellhousing seems to be coming from under turbo pouring concrete this morning so I can't take the turbo off hoping I can keep driving till this weekend leeks pretty bad while it's running though. I have no idea how this turbo works and where the oil would be coming from please help

Likely the ebpv.
Get a non-ebpv pedestal or delete yours.

Okay I've got it unplugged and blocked open that is the e b p v been running it that way most of the summer can you tell me why that would cause an oil leak I just don't understand I think we're talkin about the exhaust bypass valve the butterfly in the turbo

it's either the EBPV actuator (works off of oil pressure) or the turbo o-rings on the pedestal. I wouldn't drive it until fixed because that looks like quite a significant leak.

If you're cheap like me, I would just remove the turbo pedestal, gut the actuator and plug with a pipe cap. Gut the EPBV itself while you're at it. Install new o-rings and keep motoring on.....total cost under $20

Exhaust back pressure valve.
It can still leak with it unplugged.
You need to clean the area and find where it's coming from.

Yes it is definitely a bad oil leak but this is my 94.5 that gets a hundred miles to the gallon on oil. Yeah that's no joke. I have been working within 8 Miles of my shop all summer.
I am expecting that my oil consumption is through my injectors I have changed the external o-rings and I'm sure it's not getting past them it is internal.
So I'm going to swap the ones out of my donor truck and see what difference that makes.
Another place I see oil is on the turbo compressor side
see the picture
I don't know if that is a concern or not possibly a seal in the turbo the shaft is good and solid

Lol not internal to the injectors.
Either ebpv or rail plug. Possibly pedestal oring.
Just because the ebpv is unplugged, doesn't mean anything. It still has a constant supply of oil to it.

If your burning that much oil I'd be checking for dropped piston rings or burnt cylinders.

Are you saying that you have never heard of an injector leaking internally

It was the EVBP actuation cylinder that was leaking this just started.

No there's no way I could be leaking that much oil I may be leaked a quart or two when I sprung this leak at the actuator cylinder. The oil is going through the engine somehow I have redone the injector orings twice.
I'm sure I understand where it seals the oil from the fuel but it is still getting there somehow.
I read a good article on here how about oil leaking past internally in the injectors I will try to find it.

How bad is it smoking?

Thank you for asking since it's been hitting 40° in the mornings it smokes when I start it up now. I assume because of the cold weather , after it gets up to running temperature it does not smoke any color maybe a puff or two between gears.

What about after it's warmed up and you get on the throttle? Also when starting does it have a quick spot in the rotation? (Crank crank crank spin crank crank)?

Yeah we got a big hill that we climb coming home everyday and I will follow the truck and watch for smoke . That big hill is where I would expect to see the smoke and you almost always have some with a diesel but I don't see anything out of the ordinary. Which is strange to me considering the oil consumption. Now here's some information that I got yesterday pretty disappointing did a compression test I had 340 320 300 320 320 320 300 240 I expected to see them all near 400 because the crank pattern is consistent on startup it hits 4 times and it's running above 60° I do have a video I posted about a cold startup in a different trend.
Thank you for your interest .
I am rather sure that my problems lie in low compression I would like to hear your comments though
