Boost and cranksase ventilation.
Re: Boost and cranksase ventilation.
So those fluted tubes where exactly is the best location to have them welded on the headers? I think I'm going to try this but I see what my 2 breathers will do 1st.

Ya, you can kiss you O2's goodbye as well as your catalytic converters if you still have them with that exhaust evac system.
I've had excellent results with my current setup. No oil leaks. No MAF problems. Nice clean oil.
Drivers side PCV valve is left completely stock(one way check valve no boost leak). Passenger side valve cover gets routed to the intake side of the blower with a compressor oil/water separator inline. Check ProjectTransAM.com for info on the separator.
The reason this works so well is at idle and light throttle your PCV valve pulls good vacuum. At wide open throttle your supercharger intake pulls good vacuum. You've got vacuum on your engine all the time.
I've got 20,000 miles on my car using this system with no problems.

[QUOTE=bowtiepwr]>her is an even older pix with my nitrous set up... but notice the "filter" connecting to my Edlebrock shorties from air pump
Those are actually one way check valves for the AIR System. If you don't need your O2's or Cats that will provide an excellent vacuum source at idle. I'm not sure about a wot vacuum source. BTW Nice looking valve covers. Are they composite?

Re: Boost and cranksase ventilation.
Hmm....
I only have the PCV valve on the passenger valve cover, and a breather/filter on the oil cap location... nothing on the driver's valve cover. Is there supposed to be something there? Noticed a bit of oil leaking from a few locations after my first WOT run (finally have fuel pressure problem fixed...)

Re: Boost and cranksase ventilation.
I went with a capture tank rather than routing the oil back through the motor. I plummed both breather and intake tubing from passenger side valve cover together with a T-fitting and then routed it to the capture tank. I don't like routing the oilly air back through the motor. Even Normally aspirated, the stroker would coated the inside of the intake with oil. Now I'm running the 8lbs pulleys on the D1SC and have seen booSST over 10lbs at 5,800. Just curious if a vacuum setup necessary with a capture tank and venting? (LT1).
Also, if the oil recirculates and coats the MAF, you run the risk of going lean. I recently had a seal go in the D1SC and 4oz of blower oil got blown through the intercooler maf and motor. Burnt #4 piston due to an extremely lean condition. (I yanked the motor this weekend...that was fun). Recommend cleaning the MAF regularly if you are recirculating.
