New turbo, (6262 DBB) Oil in compressor

[TurboSmart]

Just finished installing a brand new, out of the box, turbo (dual ball bearing, water cooled)
Upon starting the car and driving it around, I noticed that oil was coming from the compressor housing to the intercooler.

Using the turbo oil restrictor (came with turbo) and the same dia drain hose. Drain is NOT pointing straight down as it hits the exhaust flange, slightly pointing to the engine.

Could this issue be oil drain related, too much oil pressure, or the compressor seals are shot?

Any pics of this?

BB turbos usually have a general 40psi max pressure, but that would require an oil pressure regulator like this ....

Usually the supplied restricter fitting does limit the volume enough to not see many seal issues.

Are you seeing any blue smoke out the exhaust?

 

[TurboSmart]

Yes..but not from the turbine, its from the intake.
Exhaust side is bone dry.

Could it be that my air filter (KN) is too small and is causing a restriction?

You're not pulling vacuum from the passenger valve cover or PCV valve into the inlet pipe are you?
This can easy create an oily film you'd notice in the compressor, I had this years ago.

Nope, valve covers vented.
Actually both valve covers are "driver" side, no hole for the vent.

Didnt had any issue with the old turbo.

 

[SCOOBY DOO]

Was the drain a direct shot on the previous turbo...cuz Patrick will likely ask...so I'll ask now to save him time.

 

[TurboSmart]

Kind off
Same diameter hose and fittings, different angle and curves. No more than 45 degrees at the turbo
But previous turbo was journal bearings, thus more oil flow
This one uses the restrictor.

nobody has ask
what brand and size is this turbo ?

so you have somebody 4 bolt or Vband header this is why the return line is a little different. the picture is a clearer today.
KN filter over oiled can put clap down stream, If it 3 inches its not to small I don't care how short it is.
GNVYus ask a valid ? If enough oil is getting sucked past the compressor wheel to smoke you have big problems.
It is a Chines built turbo,People have had good luck with Chines products.
I would make sure the air filter is not over oiled. Buicks as a general rule don't make a lot of oil pressure to push past the seal with a restricter in place.
Be prepared to here the old saying you get what you pay for

One thing for sure you spent lots of time and money to fit this turbo on a Buick. you had to build a header a downpipes wastage you must have a lot of respect for the manufacture to go this deep. Have you contacted them about your problems?
Use Buick guys know what to expect from the Buick spec turbo's but you have ventured into uncharted territory
Dynoman introduced Comp turbo with go success. Good luck with this

turbo flange was already 4 bolt. I was looking to replace my journal,tired exhaust leaking (worn oil seal) turbo.
this would be the third time rebuilding it and the turbo shaft is unserviceable.
Was cheaper to buy this other turbo than rebuilding it.

Correct Oil Feed Setup for Dual Ball Bearing Turbos​

Dual ball bearing turbochargers are renowned for their efficiency in boosting vehicle performance. To ensure their optimal functioning, it’s imperative to have the right oil feed setup. An oil restrictor or even an oil pressure regulator is highly recommended for these turbochargers. These devices ensure that the turbocharger receives a consistent oil pressure of 40 – 45 psi at maximum engine speed, which is crucial to prevent potential damage to the turbo’s internals.
This came from there website A good Buick will do this at 2500 RPM and around 70 psi at 5500 again I would look at intake side of the turbo and make sure the oil is not coming from the air filter, look at your MAS and confirm it free from oil contamination.
Today we are pledged with pore workmanship around the world trying to work with a warranty clams in this county can prove to be difficult enough.
