Turbo oil drain problems w/AAM kit

If the crankcase is vented correctly you would seem to have a problem with excessive blow by.
Personally I would take a long hard look at how your crank case ventilation is setup.
You mention you dont have the AAM setup connected, what exactly is your setup.
Post some Pics.

AAMs PCV setup had a gold check valve between the valve cover vent and the intake before the turbo. The issue is when the check valve was there I would get some strange issues when it came to pressures inside the crankcase. So I deleted them and vented the valve cover to the atmosphere. Unfortunately I can't take a picture of my setup because I have the motor back out.

I called AAM and they think I have positive crankcase pressure as well. They gave me a procedure to do to test that out but since my car isn't running I can't do that. So what I'm going to do is do a leak down test to see if I have unacceptable leakage. I don't suspect that though because my compression numbers are actually really good, but I'm going to test it just to rule that out. I'll let you guys know what I figure out. I don't plan on having the engine out very long.

Once again you really need to be sure of your pcv setup.
Boost pressure into the crankcase will also create this scenario.
The dipstick incident is the key to whats going on.
One can imagine with that much pressure, an oil return line has zero chance of functioning properly, regardless of its size. Its a wonder both Turbo's aren't crying oil.
Sounds like your onto it now though, good luck with it Mate.

I have the same problem 'Smoking Turbo's' with the AAM kit BW 71/63's.
Brand new built motor done right at MA-Motorsports.

Had to remove my car from AAM after 2 years - seems they were using my car as a Test Mule - they blew the (built) motor on the Dyno after 3 months of testing - then tried to get away with it.

The car is now at MA-Motorsports and the rebuild / build is almost done.
The AAM turbo kit smokes like a bandit due to poor engineering regarding the placement of the turbos too low and too close to the oil pan to drain properly.

Fast Intentions kit doesn't have this issue.
Looks like I'll be having to go the Scavenge Pump route to solve yet another AAM induced issue.

Should have gone with FI .... hope this helps the 'new guys / gals' considering going boosted....

MA-Motorsports just installed an RB-Racing Scavenge Pump ... helical gears and professional racing grade construction and quality.
Will comment once I take delivery of the car and test drive it ... Not expecting any disappointing surprises - MA-Motorsports has been top drawer all the way.

WOW, I knew someone had an AAM kit car in the shop. Didn't know it was yours. Good luck with it.

Wait what? Blew your motor? Test mule?

yep ... long story short ... when dealing with AAM be very wary and keep a tight hold on to your wallet. Check their invoices for double billing and made up charges.

They congratulated me when they let me know I was 'selected' to be a part of their sponsorship program --- tho' when I read the agreement/contract after the fact I realized that they had taken over complete control of my car.
To qualify for that 20% discount on parts I had to agree to supply them with professional photographs of my car - I had to advertise their shop at car shows and at the race track - and I had to allow them use of my car as they saw fit - including testing new products.
Failure to do so they could go back and charge me for the discounts I had received from them. By the way - their prices are marked up substantially from the start to begin with.
Think about it.

They used my car as a test mule to develop their Stage II turbos, their Intake Manifold, and their Twin Fuel Pump.
They had my car on the Dyno for 3 months . eventually blowing the motor.
after which the sent me a bill for $5000 + to do a Leak down Test and remove the heads to check the piston rings.
NOPE

Their Stage II Turbo's smoke excessively and the IWG's don't work will with the EcuTEK Tuning software (Boost Spikes)
MA-Motorsports installed External Waste Gates in order to correct the boost spikes and had to install a scavenge pump to correct the turbo smoke - the side effect of this was that the $6000 (yes, $6000) AAM Flex Fuel install and Tune was now trashed - kaput - useless - a huge waste of time and money.
Their Twin Fuel Pump is too complicated to work reliably (I had to replace it with the Twin Fuel Pumps from CJM Motorsports (PHUNK)
Their Intake Manifold does work acceptably but it is a compromised design in my opinion.

This is just the tip of the iceberg concerning my 2 year never ending build and horror show experience with AAM.
I was a CA$H COW.
They dangled me from the yardarm for 2 years and although they promised the world - they didn't deliver.
MA-Motorsports had to undo their work and start from scratch.

This is where you would like to see some bodies swinging on the gallows.
