Hello gentlemen. I had my 7.3 checked for any leaks recently. A lot of work was done to this engine about a year ago and many of the bolt on items that might leak were replaced.
The shop said it looks like my turbo is leaking oil internally. Does this video show that there is a problem?
if the video won’t download or play, here’s a couple screenshots.
If it's leaking internally you'll usually see light blue/gray smoke @ tailpipe only during idle and then initially when you first take off from a stop.
Blurry pic looks to show normal CCV oil vapor pooled on the boots. Unless you are loosing more than 1/2 gallon per 5k miles your oil seals are probably ok.
Thank you gentlemen, that’s a relief to hear!
this engine has just over 200K miles on the clock and it runs terrific. Acceleration is strong and idles very smooth.
The only performance thing I have a little concern about is the initial acceleration after starting fresh from a cold state. When I start out each day, I let it warm up for about a minute then drive about 50 yards to the intersection of traffic. Acceleration is like it’s starving of fuel or air. Once I get past that first acceleration in the morning, it’s fine all day. This is a bit of a pain but it runs fantastic otherwise.. is this normal?
Before I spend hard earned money on a trans cooler and gauges (exhaust gas temp, trans temp, fuel pressure), I want to be sure the engine is squared away.
I’ve been restoring this truck for the last 4 years.

pretty much normal.
I let it idle until it goes to high idle,
hit the brake, put it in gear, and idle out to the street, about 400 feet.
turn left, wait for the train to go by, hit the highway, and hit the speed limit thru town, 45 mph.
at 1 mile, town is behind me, and off I go to the speed limit again, 65 mph.

I would give it a bit more warmup. You have 15+qts of oil and like 6 gallons of coolant that need to get moving around.
Does it sound any different when it's low on power? The EBPV can fail and act like theres a banana stuck in your tailpipe.

The sound is almost hollow like maybe something is open or closed. When I step on it it gradually picks up until whatever the cause engages, closes, opens, fills up or empties... you get the idea). Like the days of naturally aspirated carbonation with the choke closed and then opens after a few seconds.

I hope this doesn't confuse...
I'd unplug the EBPV valve under the turbo and see what happens. You don't need it until your below 0F ambient. It might set a CEL, I can't remember. I unplugged mine 10 years ago and deleted the entire thing about 4 years ago.
Is it using oil between changes? I can't see the video and the pictures are blurry, but it looks like the typical CCV oil that gets into the intake side. You will see smoke if the turbo is leaking on the intake side if the leak is big enough. You won't see any smoke if the leak is on the exhaust side, which is what I had on the one that came off the Excursion. It was using oil between changes I could not tell where for many years until I pulled it to do some maintenance and upgrades.
