I drove around for about 3 weeks with a massive exhaust leak comming from the UP that i bought from ebay, the UP broke at the flexpipe. I put my stock UP back on yesterday and now my car is making a wierd noise. It sounds like a belt squealing but it only happens at half to full throttle at 4k and up. I hope its not the bearings inside the turbo. The car runs fine if i dont give it full throttle. It still boost up to 18psi where I set it. I can pop the hood and rev it to redline and it doesnt make any noise, it only makes noise when im under load, ya know, moving. And I noticed some oil on the turbo, right between the hot and cold compressor housing, so I tighten up the oil line fitting but it was already tight. What do yall think is wrong with my SUBY?:wtc:
yup..if it sounds like a kitten is getting tortured in your engine bay its an uppipe leak..have fun with it..get next to people with thier windows down and hit full boost and watch the reactions :rofl: thats what i did when my uppie was leaking
NO, I just fixed the exhaust leak by putting the stock Uppipe back on. Now its making a squealing noise at half to full throttle, and at 4k and up.
I know its easy to have the EGT sensor back out and cause an exhaust leak. That little bolt that holds it in sucks.
NOOOOOOO. I just fixed the leak, I put my stock pipe back on. Now the car is squealing at 5psi and up, and at half to full throttle, The damn exhaust is not leaking anymore. It making a really funny noise like a belt squealing.
I know what an exhaust leak sounds like. but what does a bad turbo sound like? And what does bad bearings in the turbo sound like?
You can hear an exhaust leak at Idle, My probelm is in a specific RPM and boost range. I dont know if its my turbo bearings squealing. I have to be in gear and moving to hear the noise. I can take it all the way to redline and hear no noise if I stay under 5 psi, but if i go beyond that, it squeals like hell. Does anybody with REAL turbo knoledge know what my problem is?
