Did you run it before the oil change?

Shouldn't have to bleed anything. That's weird. loosen the oil feed line to the turbo with it idling and see if you have oil. Sounds like a seized bearing. You didn't dislodge the adapter at the filter and maybe fold off the oil line or something like that? I'm sure you can get the turbo fixed for a lot less than a new one.

The reason I asked if he ran it just before is because the oil also cools the bearing as well as lubricates it that is why a cool down is suggested after a long hard run by letting it idle for a while. If not the heat from the exhaust side could cause some of the oil in the bearing to burn & crystallize seizing the bearing in time.

no you do not need to bleed off the turbo at oil changes.
sounds like the problem was there before the change.
just to be safe i always take off the supply line and fill the chamber with oil. I would make sure the the supply line is functioning properly.
man these systems need a oil priming setup.
the model # should be on the intake housing or cast in the back side of housing

i always let it cool down after a pull and put it away running perfect when i pulled oil lines off turbo the sump was dry and when i first installed it i remember it had to be reved up alittle to purge supply line to turbowith just adding some oil to turbo as it took it away as i had the supply line into the pail. i am not some green motor guy yes first rx1 but if it can be a lesson learded for some one else for the time it takes and how often the oil needs changed pretend its a new install and purge line to turbo as that is what this site is for (info). so take it for what it's maybe worth$$$$$$$$.

I was told these turbos can run several minutes at full speed without oil with no damage. I have had mine off several time and not once did I bleed it. You may have had a bad unit to start. Take your air filter off and see if you can free it up with your fingers, also see if the bearings feel rough. What brand turbo is it? Mine is made by Garrett.

Priming is not necessary. You are pushing 60 psi off the oil filter adapter into a non closed system( the case is vented ). I think Jeff said something like 44 oz. a minute. Oil gets to the bearings in a hurry. Even an external oil pump should accomplish the same thing.

When I installed my rear mount i just cracked the line at the turbo as soon as I started it to make sure...lot's of oil. When you say you didn't have oil until you poured some in, that seems a little strange, with 60psi you should have oil right now. I would double check that supply line before you toast more bearings. I have seen lots of hydraulic lines that have been damaged when made, with a flap of rubber inside, from the fitting installation, that would restrict flow. Might be worth checking. One other thing I found with mine was that the seat was pinching off the return line, had to reroute it a little bit at the rear, that wouln't have helped, if the oil can't get back it would also restrict the circulation of cooler oil.
This give me the creeps.MCX have oil inlet/outlet and oilairhose.Could the airhose been kinked?
Best way is to check that oil is feeding after oilchange but then you´ll have to rip the seat and heatcover off every time.

The trade off is the cool underhood temps, cool intercooler, less weight on the nose, more boost, more hp. I think the hose you have to watch for pinching off is the air hose, sorry about that.

It's easy to check if oil is circulating from turb. Just pull the return line off where it goes to the oil tank, if it has oil coming back you know it's coming from the turbo. I check mine often by just feeling the line warm up while it's running.

bleed line into pail before install of new unit. insatalled turbo filled oil take on bottom of turbo never looked back all week end ran perfect. i realize that it doesnt need to normally be bleed but at an idle there is only 7 psi and after i fired it up to warm it up to recheck oil level i never really reved it up high then pulled it outside the next day to load up in the trailer i never heard the pop valve go when off the throttle when pulling air filter it wouldnt turn. i am not looking for opinions as am putting this on here as i will bleed my turbo every oil change so i know its got lots of oil, which is not very often and for the 15 extra minits it is good to have a look at it any way even just for leaks etc. just glad i was able to ride it this week end and kick some #*$&@.
