Bent shaft on 71hta

What gets me is you say the "whine". The 84mm comp cover makes a whining sound when spooling up. It sounds quite high pitch. I am not sure if you have had one on before. If it is not moving in and out and only moving about an 1/8th of an inch side to side which is about 2-3mm. It is with in spec. I believe.
I not saying that it is not messed up. I am just curious...
Is it smoking? Any more pics that show the damage to the blades?

I'm not putting fp's oil line down, its just that economically speaking they use jic fittings and hose that is available anywhere. I only had search for the bspt. I dig what fp does
The shaft is clearly bent and 3 blades have dug into the surge port to the point where there is blade that rides in the surge port grove. I can get pics tomorrow of that. bearing hardly feels bad. I bet there is something else ... If fp blames my feed line for no other reason than it not being theirs then I will feel different. Afaik I built it precisely in function.

I have just purchased and installed a 71hta, along with my homebrew oil line. I primed the turbo, it had good oil pressure, and within minutes of driving the tell tale whining of compressor wheel touching housing was evident. I pulled my fp84mm intake, and it was evident that 3 blades have been worn against the compressor housing, and the shaft is visually bent. What gives?

Did you read anything? I cracked the banjo with the fuel relay out and oil was just a coming.and as stated earls inline filter , and -4 fittings and hose. what makes you suspect the an oil feed line ? anyways.

Why do you ask? Should it?
The oil line restrictor is required if the turbo has a ball bearing center section. I think that Ratty's HTA 71 is journal bearing equipped. Isn't it?
Since he's gonna have to send it back to FP to be rebuilt anyway, now would be a good time to get the BB upgrade if he has the spare cash on hand.

Turbo oiling needs specific pressure. The fact that you cracked your connector "and oil was just a coming" does not provide any useful information to assess whether you had adequate pressure.
I'm just asked you for the same kind of information that a turbo supplier like FP would want to know to assess what happened and what might have caused it...
Where did you feed the oil supply from? Head? Oil filter housing?
Either way, FP will take it apart and let you know what they find.

You' re right it didn't provide any useful information except it was getting oil pressure from the filter housing. Just as fp recommended.for this turbo if I planned to push it. which I did.
Yeah, I'm pretty bummed this happened, but at the very least it's a learning experience and not just an expense if I did make a mistake.

I was going the same route with making my own line....after i totaled it all up along with restrictor it was about $25 short from being a FP line. So i found one in the for sale thread for $150.
