After looking @fmorelli's PCV thread and reading through the replies I had the idea of re-designing the PCV system using inspiration from him and @Panzerfaust.
I've ordered the ACfab PCV fittings AN10 for the high side and AN8 low. Please have a look at the schematic below of the setup...

Hey there lads. Never thought I would have to post on forums for help but here I am. I have a 2008 335i (N54).

I need some help diagnosing an idle issue. The idle fluctuates pretty bad and comes close to stalling out. There are no check engine lights and I did a smoke test and found no vacuum leaks.
Any idea why the car will not throw any engine lights?
Thanks in advance.

Hello guys. I've been having trouble with the MOTIV flex fuel kit install. Followed all the instructions but when I connect the flex fuel module to the dme harness i lose conection to the throttle body and it gets stuck. Flashed the flex fuel tune with mhd and reseted throttle adaptation but the...
Yet another intake manifold option! Someone finally made an ITB setup for the N54 and S55 with 52mm throttle bodies. It would involve custom fab intercooler piping and would eliminate the stock throttle body (I'm assuming). Made out of aluminium and nylon and comes at a price of 4299$ (AUD?). On...
I honestly have no clue where to start this. I've been trying to self tune my N54 for a little and I cant ever seem to get everything right. Added fuel, saw the decrease in afrs (from 14-13). Did a few pulls and it felt good with no timing correction. Bumped up each load target table by 10. Did...

I have gone from a stock 135i (N54) low pressure fuel pump due to low psi (52-42psi) readings at idle and throughout RPM range (rail pressure would drop and cause limp mode), to a walbro 450 and have retained the bucket and Venturi to keep it close to stock as possible and...
