i took my turbo off to clock it for a different manifold and when i went to do the hot side i noticed this. now in order to fix this will i have to buy a new cartridge aka a new turbo or put the plates you loosen to clock the turbo and continue to run it as is. if i choose option 2 will it have a negative affects on the turbo or not just wondering what to do.

 

I have no idea what caused that, but it looks like you need a new center section and turbine wheel. I guess it could be the pics, but it looks like your turbine fins are bent and missing chunks. If the compressor side looks half as bad I would just buy a new turbo.

was ur turbo getting proper oiling because maybe oiling could be an issue

 

i would hope so i was running a -3 line to it no kinks or any thing in the feed line i was being feed from the oil pressure sending unit

 

Looks like a bad casting honestly. What kind of turbo is it? I'd send pics to the manufacturer and see what they can do for you.

 

nom,nom,nom turbine hungry

 

Honestly with the small amount of soot I would say you are losing hardly any exhaust gases through there and it obviously wasn't enough for you to notice in spool time or power. So try for warranty and if they won't warranty it, run it.

 

looks like a poor quality turbo. In to see what brand it is

 

something in the tune causing high egt's or possibly something went through the engine. ive had a turbo like that before, seals went bad and the turbine wheel ended up getting "melted"

the rust most likely from condensation, + heating/cooling/ and sitting around. you should spray the center and exhuast housing with wd-40 or something if the turbo is going to be doing alot of sitting around.

 

I'd be more concerend with the bent turbine fins

 

its a precision sc61 its about two years old i dont know i blew a motor last season with this turbo but it was only the rings that cracked. so i dont know how anything went thru the turbo

 

That could've been caused by bad casting, or excessie exhaust gas temps. But I'm leaning more towards the casting.....personally I would just buy a new cartridge if the housings are still in good shape.

no oiling issue would cause a hole in a spot like that.

to OP: do you still have a warrenty on the turbo ? if so use it, precision will probably give you a new unit

 

There's no other explanation for that than bad casting. Oiling wouldn't cause the cast iron housing to crack. I could see excessively hot exhaust gasses helping the problem along, but not ever causing this entirely. I would try to contact the manufacturer of the turbo. This may not be an isolated event and if not, i'm sure they'd love to hear about it sooner rather than later...

 

Did you buy the turbo used? maybe someone cracked it slightly when they were trying to clock it or they clamped it in a vise by that part and started hammering away at something. cast iron is fairly brittle.

 

yea its was used from one of my friend that brought it new i did not have any crack or any thing like that. and i mean i live in the north east so i did drive the car in the winter but damn ill contact precision if they cant do anything ill just get a new turbo. that just a set back

 

When a turbo gets clocked at that point, usually 1-2 bolts can't be turned out far w/o hitting something. So the housing gets wacked a few times, bolts turned out more, etc. If the person doing it went overboard, they could possibly smack it an all the force would go to that lip. If it was out far enough, it might not bend the fins, but any bit if a crack at those temps and it would sheer off completely.

 

the heat shroud shoudl be able to seal against most exhaust gages form escaping the turbine housing. As someone mentioned, it doesnt look like you had a big leak. I say use it as is until you decide to upgrade or replace the whole turbo.
