Is my turbo going?? *Video*

[98gst14b]

Check this video out of my shaftplay and tell me what you think please. A short history-the engine/turbo are brand new-has about 200miles on it. 35 Miles were operated with oil from the filter housing but it had too much pressure, I was blowing oil out the exhaust, then I switched back to the head and had it this way for about 50 miles, I replaced my wastegate spring and re-routed the hoses to my actuator see thread below...I tested it today and heard a weird high pitched squeeling right after I released the pedal after hard accel. Do turbos make this noise if they are going bad?? Thanks for your opinions.

Wow, I would have to say ya. That alot of shaft play. Does it still boost fine? have you noticed any problems?

 

[98gst14b]

it boost 26psi pretty easily no oil burning or anything

 

[JusMX141]

It's not going, it's gone.

The damage was already done with too much pressure from the filter housing. When you moved it to the head, the turbo was probably already cooked.

What do you think I should do? This turbo is 3 months old and has 200 miles!!! Is there any warrenty? How much would a rebuil cost??

Where did you buy it from?

 

[Black94DSM]

Once you get in and out shaft play its over. Sorry bud. I would just send it to get it fixed. It looks like a journal bearing turbo so it really shouldn't be much over 200 bucks to fix.

 

[98gst14b]

Dang....I got it from Peak Boost
Garrett Turbochargers

200 bux aint bad im suddenly not so sad

 

[JusMX141]

Has it been more than 30 days? Right on that link you posted there's the text: "All of our Garrett turbochargers come complete with a FREE gasket set and 30day manufacturers defect warranty."

I'm sure Garrett will try everything possible to get out of a warranty claim because in their opinion they don't build bad turbos....but who knows; maybe that one was built at 4:58 on a Friday.

I still blame excessive oil pressure. Journal bearing turbos absolutely cannot tolerate excessive pressure under load no matter how many guys will tell you to source your oil feed from the filter housing, and this is a fine example of what happens as a result.


Just out of curiosity, what does your oil drain look like....any kinks?

Hi,

Since it looks like the wheel is touching the housing in your movie, you will want to take your comp. housing off and look to see how bad the comp. wheel and housing is rubbed. Any rubbing will hurt your comp. efficiency.

Looks like he's out of luck.

 

[98gst14b]

crap

 

[JusMX141]

Yeah I got too engulfed in the warranty discussion and PM's I was exchanging with the O.P. to look back to the first post. Silly me!

A rebuild's still in the card as long as the turbine's not trashed. When a T3 turbo blows there's not much free movement space before the turbine seal lip contacts the housing. If the shaft has hit the housing, it literally files the turbine seal lip down to almost nothing, and the shaft is unuseable.

 

[98gst14b]

I think I might have lucked out, if I wiggle the wheel around and try to spin it, etc. I cant get the wheel to touch the housing, I dont think the turbo went that far

 

[98gst14b]

Turbo was sent for repair gonna be like $150

 

[greyspyder117]

where did you send it?

 

[98gst14b]

Well....I got word back from Ken at Peak Boost and he informed me that the shaft is scarred, the turbine seal is gone and I lost a lot of thrust. He told me the housings are good though but I need a whole new center section, for $480 + tax. And a whole new turbo is $619. What should I do?? PS. He informed me the turbo ran hot, and was starved of oil. I ran the oil feed according to the RRE instructions for a 91+ water cooled housing.

 

[gstryyder]

could jusmx141 possibly rebuild it?? or give a err... second opinion?

 

[98gst14b]

Well, I have been communicating with jusmx for awhile now about this. But JIC check my oil routing in the link just to make sure that it is tapped in the right hole. After talking to Peak Boost for awhile I was told on warm WOT high rpm I should get 70-90psi of oil. But I just checked pressure right before the turbo and was getting that from the housing...cold idle-30, 4k-60, 6k-80. I was told it was dead to to oil starvation. Just for the hell of it I checked the head, where my previous turbos were. cold idle-25psi, 4k-35psi, 6k-40psi. These were held at rpm for maybe 3 sec's so IDK if it would go up more but I was pissing my neighbors off .

Welp......blew another one, at 478mi. If I knew these turbos lasted 200mi I would have reconsidered buying it. Pretty much the same scenario....in and out play, little up and down, no wheel contact, puffing white smoke, turbine seals bad. This time oil was fed from the head, jusmx chime in??

 

[dsmfa9nutter]

Mail it back to them with a note about where to stick their garbage and buy oem mitsu?

 

[98gst14b]

Im gonna send it to jus see what he thinks

 

[DirtyBirdRacing]

98gst14b, what kind of driving do you usually do? Is this car usually just used for track days? Do you run it hard and then shut it off quickly? Seeing if you might be getting lots of coking on the turbine side seal which could cause it to fail.

Also, did you run this turbo with a fresh oil filter and new oil when you installed it? Bad oil will cause the turbo shaft to become scarred and will cause you to wear the thrust bearing quicker then normal.

weekend warrior, properly shutdown, primed when installed with frsh oil change.
Turns out the turbo is garbage, assembled with old parts

 

[JusMX141]

It was either assembled with old parts, or band-aided together with the previous wheels that had damage and weren't rebalanced. Either way, it wasn't going to last long the second time around.

I'll try to get some pics posted tomorrow evening.
