Default Pure turbos stage 2 Wastegate rattle - 08-30-2017, 10:35 AM

Hi!

I recently bought a set of pure turbos stage 2 high flow from a forum member, they were supposed to be almost new. This is the setup of my car right now:

-Bmw 335i n54 12/2006 AT with 120.000km
-Pure turbos stage 2 high flow with inlets and outlets
-PCV, chargepipe, bov.
-Lpfp stage 2
-VRSF 7'' Ic
-Autowerke Downp1pes
-6hp21 gearbox
-M factory diff
-Simota intake
-Precision coil over kit
-New 1 colder degree spark plugs
-Motul 300v engine oil
-Additional oil and water cooling system.
-No meth or e30. Only 98 rom(93 in usa i think)
-Tmap sensor
-Brand new jb4 g5 iso + mhd + xhp flash tool.
-Awron display

The problem comes when we start the engine, the wastegates rattle in almost all positions, except -15 degrees. They pull great at 25-26psi but in 1 or 2 minutes at idle there's lots of oil smoke coming out of the exhaust. They are 100% the turbos. How is this possible? Even if used, this kit was supposed to have the rattle noise fixed.:broken heart: .

Has this happen to someone before?

93 octane no meth or E30 getting 25-26PSI? I thought you should be limited to 20-21 PSI with that fuel.

Sorry to hear about the issues, I am getting a nearly identical setup so I will be following this closely

I think octane is different in europe. I have 98 oct here.

The turbos doesn't have 200 miles, they are from the first group buy of 2015.

I think there is a malfunction on the waste gates. I'll write tomorrow pure turbos and send them a video to see if they have other reports from early stage 2 turbos issues.

They pull great, not a single problem on wot. Smoke only on idle and that hateful rattle noise, worse than oem.

The wastegate rattle is normal for any Vacuum operated wastegate.

The smoke is from your lack of a proper PCV setup.

oil contamination will be there response most likely if you have smoke. Well thats what they told me about mine. Get rid of them and grab a single rhd manifold from a guy in Australia. He is making them up for $1600 AU plus get his modify steering rod for $200 AU.. There is so many of them getting done over here now since he has started building them. 101Duck is his nick i believe

We already replied to your 3 emails.
As we said, we always take care of our customers as best we can. As for the smoking, there are numerous reasons N54's can smoke. Kinked or bent oil drains (the internal sleeve can be damaged and not be visible externally), cracked VC, PCV setup, etc. We can check the turbos, and evaluate regarding the source of smoking. Then we will have information to report back, so we can figure out the source of the problem. First step is sending them in for inspection. Feel free to send them in for inspection, thanks!

If we told you that, then there was oil contamination. When the bearings are all grooved up, that's from oil contamination. It looks like this:



A few common cases are:

A motor that previously had stock turbos fail, then the customer doesn't flush contaminants out of their oil cooler. Then they install pure stg2, and the contaminants in the oil cooler system damage the new turbos.

OR

Built engines that are assembled, but not cleaned well enough after coming back from the machine shop. Boring and honing debris is still in the engine...

First component to be affected by contamination is the turbos. No other components in the engine spin 150,000+ rpm!

Thanks guys

It looks like lack of oil! If oil did that, can only imagine what the inside looks like!!

Just curious Pure, how exactly does one properly flush out the oil cooler when installing new turbos?

Through replacement.

Just kidding, you need some equipment though. Easiest route would probably be to send it out and have it done.

I know whenever we sell engines on n63 cars with spun bearings, we replace the turbos, oil lines, and cooler. Screw flushing. No way to be 100% sure.
