Reworked k0-4 from PG. god hates me!!

It's something you messed with while installing the turbo, just go back and double check everything. Make sure nothing is lose. A reworked turbo isn't going to cause something to fail. It's not like it's a HUGE new turbo and he overboosted and messed something up.
The sound is going to be nearly impossible t odiagnose just by hearing it. I say go back and double check EVERYTHING you touched. If you still dont find the problem, put the stock turbo back on and see if the sound goes away. If it does, tada!! its the turbo, if not, then you have more work to do. You need to start trying these things to eliminate possible problem areas one at a time. Good luck!

before we jump to any conclusions here, lets actually find out what the problem is. we know that full boost wasn't hit and the turbo did not ever exceed 5psi. the turbo still spins at idle, and the sound increases with RPM increases, but it doesn't sound to me like a bad turbo. were the turbo itself bad, you would hear a few other things outside of a rattle.
best thing to do would be to obtain a mechanic's stethoscope and use it to pinpoint where the noise is emanating from. not to frighten anyone, but it almost sounds like a spun rod bearing or walked crank. if not enough oil was put back into the engine before going out for a drive, this could easily happen. this is similar to how my buddy's speed6 sounded when his crank walked for no explicable reason. all he had was a test pipe when this happened. they ended up replacing his short block under warranty. its really not possible for any turbo of any size to cause either of those problems though, especially if you never exceed 0-5 psi. something that leads me to think the crank walked is that he says the clutch pedal vibrates. does the sound lessen or disappear when the clutch is depressed?
and if something did happen to the turbo that would cause a major issue we would take care of it, absolutely. i just don't think that is the issue here.

Dear Ken,
When I depress the clutch pedal the is more of a dull rattle that comes to my ears. I was taking turns at high speed which i heard, helps in messing up bearings. I'm taking it to a very good guy here locally. I probaly will be buying in the near future:
clutch,
rods,
piston,
bearing,
crank.....
If you could please pm with the price that would be great. And I know your not to blame, and the turbo has no shaft play and still boost.

when you said earlier that you lost some fluid, what did you mean by that? taking turns at high speeds can starve a #1 or #4 cylinder of oil which leads to premature bearing failure. if you catch it soon enough, real soon, it may be possible to just replace bearings. if it is crank walk, that would really piss me off. that used to happen to old 1.6 miatas and 4G63 DSMs just by virtue of poor design. i've always thought that crankshaft endplay on the 2.3 was a little too much.
keep me up to date on your progress and needs.
sounds like a nasty exhaust leak IMO. check to make sure the turbo gaskets are still in place and not torn. maybe check the exhaust mani too, it isnt uncommon for a new mani to loosen up over time.
its either that or i think i know where that 10 MM socket you couldnt find at clean up time went !!

i agree with Ken, does sound a lot like bad bearings. Then the logic is there; removing turbos involves removing oil lines, but it couldnt have spilled that much oil. Have you checked your oil level?

I've got a crank head trans flywheel and clutch for you for under $1500 for all of it.
