The turbo is a Precision SC34. It has around 2k miles on it. I noticed it stopped boosting and thought I had a bad coupling in my intercooler piping. After checking them all I see this...



I assume I am correct in saying that some sort of seal has let go? There isn't any oil anywhere, just soot from the exhaust.

Any idea on what failed?
Is the part replaceable? (If so, how much?)
Will the turbo need to be rebuilt (again)?

I have clocked this before: Could the bolt have just loosened over time (albiet a very short period?)

This could possibly be the death knell for me concerning my build

Thanks for any input

 

Looks like something from an exhaust standpoint. Unless that is dried oil, hard to tell

 

Nahh, its straight up soot, not oil. My oil system for the turbo is good.
FWIW, there isn't any oil/soot in the inlet of the turbo.

 

i can't really tell but it kinda looks like the turbine housing has come away from the cartridge. possibly forget to tighten the bolts when it was clocked?

 

This is my guess as well. It has happened to me. It was a very careless mistake that is going to cost me alot to get a new wheel put on my 6262.

The turbine housing separated from my cartridge and jammed the exhaust wheel into the turbine housing.

 

3rd vote for Looks like a bolt or two may not have been tightened or come lose when clocking the housing. Check it and see! Hopefully the wheel hasn't made contact with the housing!

 

Im hoping against hope thats all it is. I've got some brake clean at the house: I'll clean it up, tighten the bolts (hope I can get to em all with it still on) and see what happens. I'll update this afternoon.

If its busted, I just may very well sell the whole thing, if not just sell the car.

 

Try taking off the coupler & take a pic of the turbine fins... are you 100% sure the couplers along the intercooler piping didnt come loose or better yet one of your couplers may have a small slice? any boost leak test performed yet? any hissing during the test? Reason I ask is i had a frien who had a similar situation, but he never performed a boost leak test just assumed the turbo was on its way out bc it was old, found out the black stuff was exhaust soot due to his wastegate flange being cracked, and gasket for the turbo manifold where it bolts to the turbo was broken also..... check all these things & post up a pic of the compressor fins, if they are not harmed, im willing to bet its a boost leak your experiencing...do the boost leak test asap.

 

Wow...i think im a victim of the clocking turbo bolts loosening as well...car stopped building boost on my 3rd pass 1st time out with the car at the track...I though a rock or the rubber from one of my vacuums did this..kinda makes sense now... smh

 

Always makes for a shitty experience. Never fails. lol

 

so when that part ****s up the motor doesnt get any of that metal it just goes in the exhaust right? im interested if it will still work

 

Lol these pics hurt to look at.
Op why start a thread with out checking at least your bolts if there loose.
Why start a thread without even taking the damn couplers off and down pipe. Your here hoping someone is gonna tell you exactly what to do when you already know what to do.. start trouble shooting bro.

 

If its the compressor wheel that separates, the aluminum chips/shavings are going to get into the motor. If its the turbine wheel that takes on damage, everything will be blown through the exhaust.

 

Correct. Either way, the answer is NO. don't try to keep running the turbo. As you've physically destroyed its ability to move air.

 

Fixed

 

so is it of good measure to use some thread lock. blue locktite on the housing bolts, the down pipe bolts, heck even the head bolts for the manifold? im worried ***** going to loosen up

 

^^^^Arrrrrrrrr, thats naughty... I don't think he likes people fixing his posts (j/k)

 

Ooops lol
I dont think loctite will work on the high temps of the turbine housing. Not sure I never had the problem. Im sure those pics of the housing seperating is the cause of clocking the turbo moving on to setting up the intercooler piping and forgetting to retighten the bolts on the chra

 

I have used Blue loctite on my manifold studs because I had issues with a few of the nuts coming loose. After applying the loctite I didnt have an issue. I use it on the intake manifold nuts also. Ill probably be putting it on the turbo housing bolts as well just to prevent this from happening to me again.

 

Loctite might work at that high temperature, but I wouldn't fudge up the threads by using it because it's probably going to get baked. I'd just use lock washers on the bolts.

 

Ya it does bake up on the threads but it doesnt gum them up to where it will cause damage tot he treads by any means. Its definitely a big cushion from vibrations too.

 

FOD dude you can totally clip those and blend them... i do it all the time to turbine engines.... just cut sand repeat

ummmmmmm LOL those bitches are done.

 

My reply in bold. How about not flaming people, eh? Ish happens and this is the first time Ive ever encountered this problem
-----------------------

Well, yesterday I went out to see if I could get to the bolts without pulling the turbo: I can't (big surprise, I didnt think I could). So I said screw it and played Halo instead.

So I've gotta get time to do that (pull turbo, ect), which since I'm trying to paint my del Sol, I have no idea when that'll get done because frankly I don't want to do it in the first place.

I'll update when I actually do the work (le sigh).

 

OP if i were you, i'd at least pull the intercooler piping off the turbo, take a light and a camera and snap some photos of the fins while you still have time to make a decision about which direction you want to go...tax season will unveil a ton of deals in the market might be a good time to know if your turbo is done...then you can just source another one and pull it off just one time..

You didnt have time to check the bolts but had time to grab you camera take pics make a thread and play halo????? Am I getting punked???
Take your car to a shop and stop trying to play mechanic.
