Question about the appearance of new turbochargers

I recently purchased a new Garrett GTB2260VK turbocharger. The turbocharger looks great overall, but the inside of the exhaust side appears to be slightly sooty, and I'm wondering if that's normal.

Okay, here's the translation:

"I'm not talking about the possibility that the charger was faulty and the seller misled me. Does anyone have any other ideas?" The seller described the loader as brand new, and the fresh air side appears to be in that condition, but the casting on the exhaust side is rust-colored, and as mentioned, it's slightly sooty inside. You can also see the imprint of the metal gasket on the flange.

So, a really new Garrett turbocharger looks like this:

Yes, that's exactly what I had in mind!

If he had been honest, he would have written that he had it installed temporarily for testing purposes (because the workshop was too incompetent to diagnose a faulty mass airflow sensor).
Turbochargers don't grow on trees, and these are the most common new ones you can find on eBay.
If the oil in the turbo is still dark now, then the seller probably needs to provide an explanation .

However, the inside of the exhaust port is slightly sooty, and I wonder if that could be normal? I mean a different scenario besides the fact that the loader was installed for a short time and the seller deceived me. The seller described the loader as brand new

, including a test run, for which the loader naturally had to be installed for a short time. Because even something that comes new from the factory can still be broken:roll:.
With a successful test run performed by the seller, the loader essentially becomes even more valuable to the buyer.

The question is, why was this thing taken apart again instead of just leaving it attached to the engine?
The thought that the loader was damaged during the test run, for example, because of the realization...
"Before connecting the oil lines, the device should be filled with oil, and the oil lines should actually be connected before the engine is started."
"Zu spät kam" is obviously completely irrelevant here .

The castings may have some light surface rust, which is generally acceptable, but still indicates storage that was too humid and therefore, essentially, not ideal. A slightly oily feel to the touch would also be okay, as it means the packaging used oil for preservation. Otherwise, the exhaust side should look the same as the intake side. Absolutely no traces of motor oil or Russian oil.

Even professionally reconditioned turbochargers looked almost like new parts. The connection flanges were always freshly machined, the housings were cleaned but usually showed some light surface rust again. The turbine housing and the pressure sensor for the wastegate were always new, so it seemed they were only using used housings. And even here, the inner surfaces of the oil channels were metallic and shiny.

Just stop talking about it! I had the same thought! The oil channel is completely verschandeln on the inside, meaning it's slightly oily, but the oil itself is clean.

Send the scrap metal back. You can't buy chargers at the harbor.

I recently bought one myself from a dealer. "Quote:"
"This is a new part, as used in the manufacturing of vehicles."
Son's core components wouldn't even be installed by Dacia.
He got that thing back faster than he was here with me.

. . . .. . .or, alternatively, take it to a real expert who can meticulously examine it (bearing clearance, balancing, etc.) before it's attached to an engine.

That's interesting! The production date is March 2010, which means the charger is likely from a test engine. I'm going to take some pictures.

If you buy a new part, for example from STK Turbo Technik, you won't have any problems. Because then a completely new one will really arrive.
I've never had any problems with this company, so I wanted to give them some praise.

Okay, problem identified! Removed the discharge side cover, and looking through the viewing hole (VTG), I can see the lower edges of the compressor impeller blades - they are all damaged, indicating foreign object damage! At the exit, there were just two small scratches that made me suspicious.

Here's what likely happened: There was engine damage with foreign object ingestion in the old turbocharger. A new turbocharger was ordered, installed, and started. They probably assumed the turbocharger failed on its own and didn't realize that the engine damage and its particles were the cause. More particles from the engine are being forced into the new turbocharger, leading to another turbocharger failure. The loader was immediately removed and further dismantled.

Okay, the "fresh air" page is fine!

I'm vomiting!

Take the loader and all the documents related to the purchase to the POLICE! File a report and a criminal complaint according to § 263 of the German Criminal Code (Fraud). Since the attempt itself is punishable, I would not negotiate with the seller about taking it back, cancellation, or a replacement. You can already order a new loader. It may take some time until the case is resolved and you potentially get your money back. And you also want to repair that vehicle...

If the seller acted in good faith, which I, as a private seller, acknowledge, then I'm not the type to go to extreme lengths or file criminal charges against someone right away. We are, and will remain, human beings, so let's start by talking to each other respectfully.

Mistakes can happen to anyone, and he wrote to me before the auction ended that he had bought the turbocharger for his son, but that it had never been installed. You can't expect a layperson to know that turbochargers must be perfectly verschandeln in the exhaust tract to be a new part; I wasn't even 100% sure myself! At first glance, the loader appears to be new.

As I said, I initially do not assume that the seller intended to deceive me maliciously or deliberately concealed defects in the item. I have sent him an email and requested a proposed solution. Let's see what happens.

You can't buy loaders in the harbor!

Yes, there is more than one dealer there who sells GENUINE NEW parts .

Once, please send me a private message (PM), mulle. I already thank you!
