yes the f150 and sho engines are different variants. the sho engine is based on the transverse 3.5 cyclone engine and retains the vct configuration. the f150 is a longitudinal ti-vct engine thus the 2 solenoids per bank. the sho engine was never updated in this regard.

I'm not sure either. Ill watch it and try to check the bolts holding the halves together.
The only place that i could see a possible leak would be the break between the compressor/turbine side where the 4 or 5 bolts keep the center section together.
I doubt the turbo was built incorrectly.
This is a link to the video I was referring to.
Those/his truck turbosseem to be water cooled. Mine look like there is a plug

This fordtechmakuloco shows the screens you linked me to starting at 3:45 sec if the video doesn't start there.

I don't know if the truck version or year or what is different, but I only have 1 solenoid (cam phaser?) n each bank. Most of the videos seem to have 2 per bank?

Thanks, SHOdded.  I may not have much of anything until this weekend.

not sure where the oil is coming from unless it is from the oil filter, engine oil pressure switch, etc. if  you don't see any oil elsewhere, i would clean it off and keep an eye. possibly ptu venting but the oil would have "that smell", an axle seal leak, or the front main cover (timing cover) leak.

as for turbo videos, ones specific to the ecoboost turbos of your style should be the pertinent ones. these are smaller turbos than normal to allow faster spoolup i imagine less room for "slop" as well. but idk.

not sure where the screens are on the oil feeds, but i would hope at the end closest to the turbo to provide max filtering. will have to see if i can find this info.

I took all the turbo piping off either friday or today. I found no significant amount of oil anywhere.
The bottom of the new (rear turbo) has some  dirty oil droplets on the bottom. I have no idea where it is coming from. I shot it down with brake cleaner and wiped it off. I'll check it again in a few days. The oil return line is new and clean. The discharge hose has a flex connection which was covered with oil. It was never cleaned when they did the turbo. I cleaned that with brake cleaner as well.

I did vacuum out the CAC. I might have got a teaspoon of fluid out.

I was not able to get to the last clamp on the inlet of the rear turbo. I was afraid I would not be able to get it back on without removing the rear cat. I assume i would need to replace the gaskets. I could order them and try again next weekend.

I did put the scope down the last elbow to the inlet and everything looks clean and dry, as well as the outlet to the CAC.
I want to feel if there is any play in the shaft on the new turbo, it would give me some direction.

The purge valve does sound like it's popping while the car is running and the line is disconnected. I will get a vacuum pump to test it properly.

I also watched a makeuloco video that shows the oil filter screens for the turbo.
I don't know which end of the line they are at. Engine side?

I also watched a video of a guy rebuilding a turbo for his f150, the channel was "evil fate industries" he said there should be no slop (side to side) and a search on the internet says there will be some play and the oil will fill the gap.
So I don't know which to believe is correct.

I'm having issue geting pics to my pc to post today or I show you more.

I'll keep working at it.
Thanks SHOdded.

the purge valve should hold vacuum with it disconnected. you won't realize it with momentary tests like blowing through it.

if the impeller looks good, probably is good. not sure how it spins with engine not running/spun by hand. you can always change the oil feed tubes w filter baskets/gaskets (on both turbos) if concerned. the oil feed tubes are a known leak point on the turbos.

yes it is entirely possible there has been oil starvation on that turbo and you are seeing the results in the slower impeller response. good catch there. assuming the turbos are identically matched otherwise.

watch for any irregularities along impeller blade edges that indicate impact from the airstream.

I've been trying to sort this out in my head.
Does it make sense to you (IF the new turbos impeller spins more free by comparison) this could be the reason I never have boost building right away.
It's random when it comes on the first time, but fine after that.
Maybe it takes allot of flow to get it turning the first time.
After that it it remains spinning and boot comes on every time after the first "spool up" on the front turbo?

I don't know if this would throw any codes that I would see when scanning, I have no codes at present.

I hope to have more info tomorrow.

Thanks, Joe.

I didn't tell you, but I have 97,600 miles on the car.

I went through the intake piping on top of the engine after work today as well as the pcv system. The TB looked dryer then before.
I ran across a thread zsho had on checking the canister purge solenoid.
I'll try to check that on Sunday.

The PCV valve looks good as did all the lines, very little if any shine on the inside. I can't blow through the solenoid with it off the car. I thought I read it should have vacuum ,if it's mounted in the car and the engine is running and the electrical plug is disconnected. I don't remember.

Most of the cold side piping looked good, only a little shiny. The only spot I saw any oil was the connection just forward (front turbo side)of the BOV.

I removed the pipe connection off the front turbo. The impeller looks great. There was a bit of oil on the machined inlet. I assume the BOV venting back into the filtered air is where the oil came from.

I turned the impeller with my fingers. It didn't turn hard, but I assumed it would turn easier, like a fidget spinner.
I grabbed a hold of the shaft and I can feel some up/down/side to side play. It's no allot, but I would not think there should be any play. I check it against the new rear turbo on sunday. I'll also see if I can vacuum anything out of the CAC.

This is the kind of thing I keep finding from the dealer I went to.
The hose connection from the  BOV. So disappointing.

I'll also get the engine mount (bracket) ordered.

Thanks, let me know what you think.

I did order a pcv valve from tasca.
I'll look at your links,
Thanks.
I have been searching for the mount all day. It may be just a bracket.
Thanks SHOdded.

I got my tune yesterday.
I wonder if I can use the log file by itself and maybe it'll show something.
It seems like the first time I floor it the boost is random as to when it will build, but after that it's normal.

I plan to get the car up on stands tomorrow or Sunday and go through the piping to clean it.

Thanks, for the links and help.

the pcv valve comes separately and as an assembly. replace the assembly.

is that cracked part from an engine mount bracket? replace mount/bracket assembly if so.

I took a look at the TB after work today, only a bit of oil.

running inconsistent after work and some surging at part and full throttle.

I did notice this.
I don't know how long this has been broken.
