So, last night i took off my oil feed lines to add some thread sealent since they seemed to be leaking a bit of oil. After putting them back on i drove around for a test drive to see if they were still leaking. After boosting a few times i hear a really strange and apparently terrible noise. So then i boost it again because im retarded to see if it happens again...sure enough it did. So then i decide to limp it home. Well then it started doing the noise even under partial throttle. Once i get home i open it up, everything looks fine visually. So then i take the air filter off and rev the engien while shining a flash light into the turbo. OMFG.....the turbo came to a dead stop everytime i revved the engine (which was causing the noise). So i took the oil lines back apart and it looks like something apparently fell into the turbo inlet (dont ask how) that was partially clogging the oil feed.

Now it is fixed, but the turbo whines a heck of a lot more and there is significantly more shaft play. The compressor wheel has some scraping marks on the housing too This is a turbonetics 60-1 journal bearing turbo. Should i be shopping for a new one or will this one last a bit longer?

I'd pull it and send it in for a rebuild

what happens if i decide not to fix it immediatly? I have a problem that my friend who's garage i usually work in just moved to boston.

If you already worn the journal bearings down to a point where it will contact the housing and continue to drive on it, you are driving a ticking time bomb. It is only a matter of time before the turbo contacts the wheel hard enough to catastophically fail and risk sending a compressor wheel through your engine. A simple rebuild will not be as good as before because as soon as there is wheel rub, your clearances are increased, which decrease your turbo's efficiency. I would get a new turbo if I were you.

Too late, if its contacting housings its junk. Time for a new turbo.

so what about this post has anything to do with a Rotary Engine?

in anycase you say it scraped the housing already.....so shavings already went through your engine......hmmmm

recomendation rebuild or new turbo

rebuild quote is 400 bucks. I bought the darn thing for 500 used. maybe this is a sign i should buy a gt35r? anyone have a turbo for sale? 60-1 size or a little bigger maybe.

pretty tough to send any pieces of a turbine wheel... into the engine....it has to first go through the intercooler...
think of it as a big air filter

I'm with the logical thinker... Did you guys think the intercooler was hollow?
