No possibility that that c clip is in there right? WG still tightened up and all?

fwiw, I emailed Dustin at emotors, asked if they recommend oil restrictions. Here is his reply:
"YES, DEFINITELY – WE WILL BE UPDATING OUR AUCTIONS TO INCLUDE THAT INFO – WE CURRENTLY DON’T CARRY THEM BUT THAT SEEMS TO BE THE PROBLEM – OVER OILING J" |
huh, wow crazy how that works^^^^^^^^^^
|
The instructions that came with my Garrett (journal bearing) called for a restrictor, I've been using a 1/8 pop-rivet(with the nail part removed) in the oil supply line fitting as a restrictor for two years.

Ask him to explain exactly what over oil is. I bet he can't give you an scientific explanation. That's because there's no such thing as over oiling or over lubricating a bearing. AAMOF the less time a given unit of oil is actually inside the chra the better. If you must run a restrictor in a journal bearing turbo then there's either some kind of pressure build up in the oiling system or the seals are worn in the turbo.
I've read several times on the DSM forums that the eBay 16Gs aren't balanced even though they look like they are - and the turbine and compressor wheels are excessively heavy compared to a name brand turbo. The instructions from Garrett? Because they're website says journal bearings do NOT need restrictors. AAMOF their engineers say that too. :dunno: |
Well everywhere I've read has talked about using a restrictor...especially with the egay turbo's. I've also been using the pop rivet.

m2cupcar,
I did'nt say the instructions were from "Garrett" I said the instructions that (came with my Garrett) the instructions were from the supplier. |

So I got this response from the seller.....
That model GT28 should be the journal bearing type and in which case I would have no explanation as to what the noise could be, unless you were mistakenly sent a ball-bearing (of which we've stop producing) and those would be the bearings. As long as it works and makes boost with no smoke I would't worry, but if it gets to the point were you'd like to return it within 30days of original purchase I'll be sure to send you the correct type.

that's a pretty cool reply from the vendor. from what you described to me earlier it sounds like you have a BB turbo. needs more video of you spinning it by hand....
|
The only reason I can see for a restrictor is to keep from blowing oil through the seals when the oil can't drain out fast enough and builds too much pressure in the bearing area.
|
So if it is a ball bearing turbo and the problem was caused by too much oil pressure wouldn't you have oil blowing through the seals directly into the intake and exhaust? Got symptoms of that? Chalk it up to a piece of shit product then.

Over lubrication is a leading cause of bearing failure. |

I'll get a video tomorrow. __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
No lateral shaft play could be bb. How does it spin right now if you spin it by hand? And you gotta wonder why they stopped selling the bb turbos... ;)

That said, please explain over oiling of a journal bearing turbo (and I'm not speaking of excessive pressure blowing oil past the seals). :hustler: |
So yeah, I think I'm gonna go ahead and return it. The noise is getting louder, sound slike some juiced up electric car driving by. I just hope that they send me something with the same specs.

There is no such thing as too much lubricant. Trust me.
