    You need to check the size of the orifice first. Ball bearing turbo's can get by with as small as a .030" restrictor, but that will smoke a journal bearing turbo. Take one of those and drill it out with a 5/64th drill bit (.080"). If it still smokes drill the other out with a 1/16th drill bit and try it. If it still smokes after that you will need to address the drain or you have another problem such as crankcase pressure or bad valve seals. Make sense?

    Greddy makes them, I just use "key on" for power. When I shut down, I leave it in the on position for a few moments while I'm putting up windows, finding my cell phone that flew somewhere in the back seat during a pull and such.

    Similar to what I did. I just have a switch to turns it on and off when I need too.

    Probably just leave it that way. I have to run mine for atleast 1 minute or else I get smoke. Helps to run it before I start the car too, I think

    Hopefully they will have kept their panties on so we won't be cleaning up the mess when they soil themselves......

    Thanks , the drain is an10 to 8an plug adapter
    running directly to the side of pan with an10 is good?

    Whats the dipstick set up like? Seams like a long route?
    is there an adapter where tube meets block?

    I'm not sure if m50 has the ccv tube on the side... someone chime in?

    I'm sure m52 would work though.

    You Would just run the line to the side of the tube where the ccv connects used to connect. Drill holes in tube under oring seal

    Any pics on the dipstick drain set up?

    Butters idea of drilling plug to larger and T hose to catch can sounds good as well

    - - - Updated - - -

    Will do, T off mid way and run hose to top of motor height?

    Yes. It won't over flow.

    Since you don't have a catch can what about running the vent to the vanos plug with an adapter? Idea credit to 328ifun and Butters.

    Someone please shoot this down if it's a bad idea. I think I'm going to try it.

    Looking at where my manifold sits I can't imagine there's enough room to drain to the vanos plugs. I do think I'll use it as a vent hole though.

    I also think venting to the vanos plug sounds like a reasonable plan but only if the crankcase pressure is not too high.

    Installed a T and ran vent line with temporary filter.
    no smoke but a mess of oil. Seems like to much oil even if a catch can installed
    I believe this an8 drain plug adapter is not working
    I plan to tap into side of pan at highest point with an10 fitting to match hose
    any feedback?

    I was informed by my tuner that if you drill while pan while full of oil, the oil will push out shavings as your drilling
    use grease on tap when tapping to grap shavings
    if any shaving do enter pan, pan is aluminum/soft and will not damage
    he has done many this way
    are you top mount? What is your return?

    Maybe so. I'd be nervous about drilling with the pan on but sounds reasonable enough.

    No I'm bottom mount and I have a scavenge pump.

    Solenoid on electronic boost controller that's not working. That's been my issue with the boost controller. Ran manual boost controller temporarily. And ran close to 10 psi . Felt great but in third fourth gear I believe it's slipping
