Crank case pressure! Showing the data!

[@Mr.SlipperyX]

well done. well done

[@Mr.SlipperyX]

always learn a ton, now i need more data i can prob check the health of the motor long term

[@onebads2kracing]

Yes sir!

[@danielpugliese7003]

If you use connect a catch can to the inlet of the turbo you can use that suction to create a vacuum on the crankcase

[@ThatOneCatNyx]

Only issue with that is if he has a MAF in blow through position the oil can destroy it. Some OEMs do that- but they have a MAP sensor post turbo, and a MAF pre turbo.

[@onebads2kracing]

This can draw in oil deposits as well and lower the octane of the fuel

[@danielpugliese7003]

@@onebads2kracing not if you have a decent catch can

[@onebads2kracing]

@danielpugliese7003 you’ll still pull in oily air no matter how well built the can is.

[@inovatv1]

Wonder if you should just leave the original catch can hooked up as well?

[@onebads2kracing]

I actually tested it capped recently and only built a additional 1-2 psi more :)

Would you be going to start using Valvoline P&R for this car?. 😂😂😂

Hey dude- I have a BMW E46 330 that I am building an M50 2.8L stroker with dual VVT and a big single turbo. My setup has a valve cover with a built in Air/Oil separator that I plan to hook up to a venturi vacuum generator on the exhaust- with a check valve. My last setup had no air oil separator and vented straight off the top of the valve cover to a 1in barb fitting. Said last setup would spew oil vapor all over my engine bay- so I ran a dump hose under the car as a temporary fix (that ended up lasting over a year until the car was totaled XD). I'm very interested to see if adding venturi exhaust suckers to your catch cans as a vacuum source would furthur reduce your crankcase pressure- even seeing if you get constant vacuum on the crankcase while in boost. Oh P.S. What did you use to datalog your crankcase pressure?
