Blew up the HX35 Turbo already!?

- Blew up the HX35 Turbo already!? I made a poor and dumb decision to let a "boost leak noise" go for a few days without doing anything to try and fix it. I thought that the boost leak noise was possibly coming from a very tiny crack in a intercooler boot on my 24 valve cummins and thought I could get by for a few with it. Come to find out, there was a hx35 turbo oil drain leak. One of the bolts on the hx35 turbo oil drain had worked itself loose a little bit allowing the turbo oil drain leak. By having a little turbo oil drain leak on the hx35 turbo, it was making the turbo run hotter than it should be from not getting oiled properly to cool it down as the turbo spools up. Due to the turbo heating up from lack of proper oiling, that most likely caused the whining sound that I originally thought to be a boost leak on the 24 valve cummins. The hx35 turbo oil drain is now tightened back down and I also installed the new hx35 oil feed fitting that I ordered. I will keep an eye on it this week and take it easy on everything to see if it clears up the whining noise now that the oil drain is tightened down again. I'm hoping that I didnt damage the hx35 rebuild kit that I just installed on the turbo by not looking into the whining noise sooner. I could have very well just ruined the turbo and have to pull it back off the 2nd gen cummins to rebuild the hx35 again, from not thinking to check the oil feed and oil drain sooner. When the turbo doesn't get oiled properly, it doesn't get cooled properly and heats up from spinning so fast while creating boost and the lack of oil WILL cause the whining sound that I heard. It could also be that tiny intercooler boot crack and possible boost leak, but I have a feeling it's from the lack of oil. There may be another hx35 turbo rebuild coming soon, or a bigger hx35 turbo upgrade. We will see how this week is and keep an eye out for more cummins turbo failure symptoms, and make a decision based from that.

I'll be making some phone calls today about some stuff. hmmmm... wonder what it could be about!? Any guesses?
new turbo ? haha
How much oil pressure have you got, the oil flow to turbo is controlled by a orifice after the supply pipe in the housing, that didn't get blocked somehow ?
Been a while since I've stopped by. Great videos btw finally got my 12v running great love diesels now. Sorry about the turbo problems, all about trial and error hope you get everything running perfect soon. I know you'll keep us updated! 👌
Jevin Burgess I'll get it all straightened out. Just a dumb mistake on my end from being lazy really haha.
Can’t wait till I get a Cummins till then I’ll keep watching and learning
I see no reason why a drain leak would make a turbo run hotter.
You're absolutely right. I was just thinking out loud out of frustration rambling on while recording sounding like a fool 🤔. Not really thinking about what I was saying all that much. I've been called out for that a ton of times now.
Good video. I wonder if the turbo was pre Oiled before your installation I had Oiled my replacement turbo apron install. It's a constant battle keeping up with the diesel but when you get it dialed in its going to be unstoppable. Don't get discouraged & send it !
Abraham Salcido I oiled it when I rebuilt it and before installing. Not sure what's causing the issue but itll get figured out and be better than before!👌
Hx40 is calling your name!
kenny etenne 👌🤐
No, No, No! Hx40 has a weak center shaft known to fail. An upgraded hx35/hx40 hybrid built properly is a solid option, but money would be better spent on numerous aftermarket units. Affordable ones are out there.
Soooo what was the reason the bearings got smoked? I’m about to rebuild one myself
the country looks like a nice place to live
It is pretty peaceful for the most part!
Wtf why does the turbo spin so freely? That’s impressive. spins like a ball bearing. my holset doesn’t spin for shit
Your set screw will not reduce the pressure applied to the diaphram , it will only change the rate at which the pressure will rise .
I’m stuck at work trying to get a turbo or rebuild and have to drive to work everyday in my hy35 with it squealing just like yours. Its been 2 weeks and still running. I’m far from home to do anything else about it.
The bolt being loose wouldn't mess the turbo up
Was it a boost leak? What did you end up doing?
oh crap !! how much money do you have to put into this cummins !!! most weve spent in repairs on our 6.0 is for a wheel hub. those old 24 valves are supposed to be really reliable right ? time for a 3rd gen i think !!
That Powerstroke Bloke the 24 valve is a great truck. But it's just time for all that maintenance to be done and I want to add some fun parts into the mix as well. I've gotta keep content flowing for the channel some how! I would love a 3rd gen, but I'd still go right through it and start replacing things. I'm almost done replacing everything I want to on this truck now, so we can start thinking about bigger and better mods down the road.
sweet man !! looking forward to that !!
The spec on Holset HX and HY radial movement is 0.013" - 0.020" pretty lose in my opinion...
Theres definitely a tiny wiggle In them when they are freshened up or brand new. I thought it would be a bit tighter but I just ran it anyways. Itll get swapped for something different eventually anyways.
Just get a 63/68/14 from smeding Diesel in Texas, only 995 on Mdc Diesel
Brandon Zervos I'll check them out today! 👍
Do you have one? Looking at one of them or the aurora 3000, or stealth 64… so hard to tell from the videos available
It sounds like all the hx35 I’ve had also I’ve never had an adjustable boost elbow mine have been plugged from day one
Josh Stephens this was completely my fault. My own stupidity not looking into it sooner. My negligence killed this fresh rebuild haha. It'll be straightened out though.
I plug mine off to getting ready for compounds tho
pure panoRAMa What was your fault? Did I miss something or the correlation between adjustable boost elbow and plugging?
I wouldn’t beat yourself up over this a leaky drain on turbo will not cause failure now if you starved the oil feed That would cause failure I use to truck pull Cummins trucks for many years over spooling and high drive pressures are where the most common problem occur
cmorga43 morga I was just saying that I thought I messed up the hx35 build by not paying attention to the noise I heard a lot sooner. Something happened where the journal bearings are now cooked and the turbo needs a rebuild again after a week.
Suzuki Every Wagon Turbo
I changed Turbo of my Car three time but i still facing problem turbo oil sucking..
My car Turbo blow oil ... plz guide me. Why again and again Turbo blow oil
If guess oil pressure needs to be bumped or there's just a oil issue. Even if its maxed out it shouldnt be blowing. Smoking turbo means the oil seals are toast. Or you are burning oil from the engine?
What turbine housing is that you have on it is it smaller than 12cm?
12cm yes
A loose bolt wouldn’t mess up a turbo. It was that cheap rebuild kit bud. If there were an actual supply line issue maybe but all a loose bolt on the return would do is make a mees
If it stil builds boost you should be alright
Music is awful.
Lol dude, have a leaking drain has no affect of oil flow TO the turbo. It needs a proper rebuild! Send it out to have it rebuilt and balanced. Also stop saying DAT every other word. Seriously if this was a drinking game I'd be smashed 5 mins in!
Sorry man but I can’t listen to your motor mouth very long
