Cruez Posted August 11, 2003 Share Posted August 11, 2003 Ok, almost got the car up and running again... need some final pointers... 1. There is pipe coming out of the crankcase that goes into the PCV valve before entering the intake.... which is two completely different sizes at each end....(pipe and pcv valve) what have you guys done instead of the factory pipe? 2. The vacuum hose between the valve cover and the thottle body..... Since I have the 240sx TB on there now and no place for that vacuum line to go.... do I put a filter on the valve cover or block it off??... should it even be vented to the outside air?...in its stock form, I noticed an rpm drop when you took the oil cap off....

Cruez Posted August 12, 2003 Author Share Posted August 12, 2003 Come on.... Nobody has any insight on this? Quote Link to comment Share on other sites More sharing options...
Dayz Posted August 12, 2003 Share Posted August 12, 2003 Those are for emission purpose only, if I'm right. Every vacuum that you can put anywhere, block them, like the one on the TB. On my former engine, I blocked both!! Hope it helps... Dayz Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 12, 2003 Share Posted August 12, 2003 If you vent the valve cover, you should vent the crankcase too. If the PCV valve is installed, you'd have to block that as well. Otherwise, yo can leave it all connected, and install an oil trap, and maintain the PCV system. That will keep oil odors and mist down under the hood.

Cruez Posted August 12, 2003 Author Share Posted August 12, 2003 Ok, I want to keep the pcv system... What about the two different sized ends?...any ideas? And if I keep the pcv sys... I am assuming I should block off the vent for the valve cover...right?? since I have no termination point for it anymore... Quote Link to comment Share on other sites More sharing options...
TimZ Posted August 12, 2003 Share Posted August 12, 2003 The factory pcv hose was actually larger diameter on the crankcase end. If all of your pcv stuff is in the stock location, just call courtesy Nissan and get a pcv hose. Sorry - what was your setup again? My advice will differ on what to do with the valve cover, depending on what you've got. Quote Link to comment Share on other sites More sharing options...
Cruez Posted August 12, 2003 Author Share Posted August 12, 2003 N/A setup... 10.4:1 comp Haltech E6 Shaved intake 240sx TB etc.. I don't need any of the stock vacuum lines (ie, distributor, egr, etc..) Just for the pressure regulator, brakes, and MAP sensor.. Quote Link to comment Share on other sites More sharing options...
