Some days my truck will make 32 lbs of boost and others it struggles to make 24-26 lbs. the vgt command and actual seem to be reading correctly, do you think its still a turbo or something else?
Hello I was hoping to get your help. I have an excessive amount of oil coming out of my speed sensor on my turbo. I have replaced the o-ring on the speed sensor but it is still coming out when truck is running. Is there supposed to be a lot of oil in the sensor port?
@@DIYKAI do you want honk it’s possible to be leaking into the turbo? I’m getting excessive pressure build up in my radiator and it’s pushing coolant into the reservoir. I’ve done a pressure test and combustion gas test already.
@@HanktheTank349 if your building pressure it would not be from the turbo....pressure test will only show you a leak.....you might have some head walk or a head gasket starting to go out....have you checked the torque on your head bolts I have seen them loose before
@@DIYKAI I haven’t checked the torque on them yet. I’ll look into that. I have to rebuild the turbo anyways, the bearing is making a high pitch noise… which is why I found your video. Thanks for your help
@@BigDaddyLanny just make sure you have no chipped fins and the shaft is smooth….witness marks are ok as long as when you run your finger nail across it don’t grab
My turbo Identical.. except. The gear tooth has lines on the turbo to lign up with. One is full vgt other is none. This is in the cummins manual and used during calibration. My vane cartridge has two snap rings. Both are in the hot side snail and impossible to remove. Looking down into the hot snail, first ring is inside to capture center cartridge. In addition to the outer clamp. Second one locks the vane plate into place. These are cummins holset turbos. So not sure why yours is missing these.
@DIYKAI this is a 2018. However the earlier ?2016? Has dame build just different hot snail. Still has the c clips. Only way I can think to get the vane disc out is to destroy it.

Check all your boost connections and the intake manifold gasket they are common to leak
What's the name of the tool?
the one that drives the seal is this one:
amzn.to/3ttSDc8

No Zero oil should be coming out of the turbo have you checked for shaft plat in and out and side to side
Awesome video!!! Very detailed and connecting yourself on a couple things, even better. I REALLY want to see the second half. Keep it up man!
Thank you! Just as a quick update the turbo has gone cross country twice and is still boosting 36+ PSI EASY
Damn how TFdo you get the turbine housing on the fucking thing. You can’t see inside the mf where the nozzle blades go
What part are you trying to assemble?
What year truck is this off of? Mine is a 2018 but I think it has a he300vg
2012 but they should be similar
Quick question for you… have you ever seen the coolant side of the turbo leak?
@@HanktheTank349 from the line connections yes

@@HanktheTank349 your welcome and good luck this one is still running strong just ran it up the east coast
I heard you say you got the rebuild kit off Amazon but where did you get the new vgt part of it? Links would be great.
I will drop the links in a few thanks
turbo rebuild kit:
amzn.to/3OBYIuG
VG Nozzle & Ring:
amzn.to/3QmLX8E
Thank you sr
Your welcome!
How come you don’t post the difficult part that’s really smart
What difficult part?
Where did you order your parts from? Great videos also.
Thanks we ordered everything off Amazon. We can provide the links of you need.
Great video!
Thanks!
The local turbo guy says the turbine has to be rebalanced, is this true?
Not true at all…..mine has well over 20k now and still boosting 35psi +
@@DIYKAI anything I have to be cautious of? I took mine apart and didn't want to go past the turbine removal because of that lol
@@BigDaddyLanny just make sure you have no chipped fins and the shaft is smooth….witness marks are ok as long as when you run your finger nail across it don’t grab
@@BigDaddyLanny clean off as much carbon as you can with very fine Emory or nylon avoid scratching the shaft
@@BigDaddyLanny now if you were replacing the turbine shaft or impeller then a balance would be fine
My turbo

My vane cartridge has two snap rings. Both are in the hot side snail and impossible to remove.

These are cummins holset turbos. So not sure why yours is missing these.
What year and model truck?
What’s the turbo number? Cummins made 2 different turbos to my knowledge
I have a special calibration tool so it didn’t matter for us
@DIYKAI this is a 2018. However the earlier ?2016? Has dame build just different hot snail. Still has the c clips.

@@turboflush yes we had to collapse it and deform it to remove. 2016 was the later style turbos....2013 they started to change them
