is this shaft play?

[jdmawd]

ok here is the deal i hava about 1500 miles on my turbo. with minimal boosting other then tuning runs, and the occasional street encounter. the other day i noticed that i was only making 15 psi with no changes to the boost controller . i started looking for a boost leak, but could not find one. so for the sake of argument i stuck my hand in the compressor housing and the compressor wheel moves back an forth about a half inch to an inch. no side to side play but excessive in and out movement. the compressor wheel is not damaged nor is there any contact to the compressor housing. is this shaft play or something else?

 

[RabidDonkeyBoy]

is there oil in the compressor outlet or blue exhaust smoke?

 

[DSMJim]

in and out half an inch? wow that's is very execssive. I would say there is some type of defect there. If it was me I would call up where I bought it and try and get some warranty on the turbo.

The most a turbo should move is a 1/16th of an inch to an 1/8th tops.

i agree the half inch/inch was very modest, it actually moves in and out a ton. this is a new situation, i chech for shaft play fairly often.i noticed this when boost started to fall rapidly.

RabidDonkeyBoy:

there was some blue somke during idle and under boost a while ago. which i assumed was caused by leaky valve seals. strangly after a oil change, that condition went away. i have not looked at the outlet side of the turbo yet so i dont know. i dont know a ton about turbo's, but it looks like whatever connects the turbine wheel to the compressor wheel is not connected properly. there is no side to side movement which makes me think its not a bearing issue. would that be a fair assumption?

Without starting a fight, a large percentage of people who have bought turbos from that particular vendor have had the same problem. I am sure they will be able to handle your warranty claim no problem.

I Know I know, your restraint in this matter is noble. on the topic of not starting a huge flame war, what could cause this type of situation at only 1500 miles and no track time? it cant be bearing failure because there is no side to side movement. is there some type of clamp that holds the turbine wheel and compressor wheel together that could have loosened up? im more interested in the mechanics of the problem.

If you have that much axial play in the shaft/wheel assembly there is a problem. Even though you don't see any sign of the wheels hitting the housings, I'll guarantee that your thrust collar/spacer/bearing has been eaten through the seal plate on the compressor side. Turbine side probably has damaged the wheel and piston seal area.

This can be caused by a number of things, and best bet would be to send it back to the manufacturer for proper diagnosis.

cool that's what i was looking for. what are some causes for this type of situation. im sure you have seen this happen before. if this is user error i would like to know how to prevent it in the future. im sure once i send it back the vender will explain exactly what the cause was. i would just like to know what i can do on my end to prevent this from happening in the future

Excessive thrust wear can be caused by:

Stiff BOV or no BOV (probably not the case)
Clogged Cat or restrictive exhaust (probably not the case)
Contamination clogging up the oil feeds in the thrust bearing

The only way to tell what happened is with a complete disassembly and inspection.

ken is always busting on my ride:laugh: im a good sport about it i just want to know what caused this so i dont have a similar problem again. ill keep you guys posted on the results once it goes back.

Is that suppose to hurt me? If that was what you were trying, you didn't succeed. The Escort makes for a great winter car, it's $22/month to insure, and is great on gas, can beat that.

And yes, it is quite funny when it comes to your car, you'll have an easy time now when you go up against Greenstreak and Dsmman.

It's OK, I'll give you a hand pushing your car down the track when you race Keith and Erik :laugh: :laugh:

yup i actually love this turbo, and cant wait for it to be repaired. dsm-performance has made this issue a priority. i am very happy with the customer service and all products i have received from dsm-performance. i appreciate the offer to help me get my car ready for me and Erik's little grudge match. it seems you are not in the know. because you seem to think there is some type of ill will between Erik and i. we talk quite frequently, and he is the first person i told about this little turbo situation. we actually were introduced by a mutual friend. have a great day, and thanks again for the help. if i need anything you will be the first to know.

:laugh:

So let me get this straight - you had a problem with him for pulling the Mutt of his car and putting on the Green, then you recently told him he was right all along? Ahaha, you tool....Open mouth, insert foot :laugh: MFAO :laugh: And don't try to deny it either.....you're busted :laugh:

I didn't know turbo's were 'wear items' and needed changing every 1500 miles. Good luck with it!

Neither did I, we will see what the cause was once I get it shipped out. Dave (gsx4life) came down the other day, and I showed him the turbo. he said it was the exact same thing that happened to Erik's turbo. (maybe worse)

Seriously for type of PR work you have done for them they should fly out on the next plane and install the turbo for you while you watch and have strippers hand feed you grapes :laugh:
