Yeah it's normal for anything to wear out over time and obviously when you increase the strain on a part it will wear out quicker. There are plenty of variables that go into how long a turbo lasts.

 

There is a bunch of info on this site that pertains to removing the stock turbo oil filter and replacing it with an aftermarket version. @k31th or anyone else, would you mind doing the honours and linking some stuff, perty please?!

 

I had a turbo make your exact noise on my xr6t and I replaced it immediately so I can't say firsthand how long yours would last. I personally wouldn't run it stuffed for any longer than I had to. You could nurse it for a while but it won't get any better and eventually the compressor wheel will touch the housing and start adding ground metal to your intercooler. The bearing assembly will be adding a small amount of metal to your sump and eventually add quite a bit more.

 

In short, it's farked and you should replace it asap along with checking or replacing the oil feed.

That'll do. :thumbsup:

 

As for replace, repair or upgrade there are a few choices. I prefer the upgrade path as some or most of the cost of an upgrade is already accounted for in a repair or replace.

 

For repair there is an aftermarket journal bearing option, an aftermarket ball bearing option, a genuine chra option, along with a few billet wheel aftermarket chra options. These can be easily replaced at home. You could take the turbo to a turbo specialist and get it repaired. There was an advertiser on this site a while back offering repairs and upgrades. From what I gather any repair is using an aftermarket bb assembly but I'm not a turbo shop guy so I'm not 100% on this.

 

Replace is pretty straightforward. You track down a stock turbo and replace it. GCG turbos do a stock replacement. You can replace it with a used turbo. I wouldn't bother with 2nd hand myself but if the shoe fits then it can work.

 

Upgrade is what you make it. The best cheapest option to upgrade is to drop a gtx supercore in. This could involve hotside intercooler piping replacement, fresh air piping/air filter replacement and obviously tuning in any case of an upgrade. There is a bolt on gtw3884r upgrade available from a couple of shops. Then there is full aftermarket upgrades of which you'll find details in the 500rwkw+ threads.

I put an earls kit on & removed the factory one about 15months ago and checked the filter just 2 weeks ago while I was fixing a leak from a fitting, all clear. How quick could this happen from oil starvation? I'm now thinking I could have possible used too much thread sealant and blocked the turbo oil inlet hole??!??

 

Upgrade was my first thought (new turbo, fuel system, valve springs, oil pump gears, retune through CMS.) But then remembered I'm broke.

 

I'm country based so no turbo specialists nearby. An at home rebuild or second hand unit are looking like the most likely options atm, retune is a 6hr drive away. Will hopefully be doing above upgrades in 12 or so months.

No oil at all would fark it very quickly. A reduced amount of oil would be ok with gentle driving but boosting it would fark it quick. I don't think you would have blocked it but anything is possible.

Sounds like a plan. You can definitely replace the chra at home. From my recent browsing there is a journal bearing chra for around the $300 mark and a bb chra for around the $600 mark.

Lights in under the hard cover. Had the stuff sitting in a corner for a few years now and finally got the motivation now its getting dark earlier to do something about it.  Took a fair while longer than I expected to get done but fairly happy with how it's come up. Very even light in the tub too.  My only wish would have been a spotlight that could illuminate the tow hookup, but the angles don't work. I'll have to come up with a plan B there.
