Ron240zxt Posted May 5, 2004 Share Posted May 5, 2004 Hey all, Got a question concerning the breather assembly, What diam. hose is required or recommended, -8 / -6 maybe larger? The hoses are going into a catch can, vacumm source is from the intake piping before the turbo after the filter. I also need to know which way the check valves need to be positioned of the valve/block breathers? Any help would be appreciated. For the ones that dont know my car, it is not "Stock" Nor have the factory manifolds, so plumbing is alittle difficult. Here a picture or link to my engine bay so you can see what i have to work with, Sorry about the mess.

preith Posted May 5, 2004 Share Posted May 5, 2004 If emmisions are not of a concern, I would leave it vent to the atmosphere. I was running mine with the lower breather (in the block) removed and freeze plugged, and a K&N breather filter on the top. Quote Link to comment Share on other sites More sharing options...
Synlubes Posted May 6, 2004 Share Posted May 6, 2004 I was running mine with the lower breather (in the block) removed and freeze plugged, and a K&N breather filter on the top. Ditto here. 25mm freeze plug in the block and K&N filter off the valve cover. I blocked off the block due to a "mature block" blowing some oil out at track events. With just the valve cover vented, no problems. Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted May 8, 2004 Share Posted May 8, 2004 if your car is blowing oil out the block vent tube... shouldn't that be a sign of another problem? -Ed Quote Link to comment Share on other sites More sharing options...
Synlubes Posted May 8, 2004 Share Posted May 8, 2004 I blocked off the block due to a "mature block" blowing some oil out at track events. I should have said, blowing oil out the block vent tube. I also run 6 quarts in the crankcase at track events and the problem only happens thru turn 10 at Summit Point (fast long right hander). Note "mature block" meaning, - old - wore out - on its last leg - many thousands of miles - needs work - hoping I don’t blow this thing while I’m here (on track) But hey, running Amsoil 20w50 and it just keeps going and going and going . . .
