I have heard many times that these l28 EFI engine will stall if you remove the dip stick/ pcv hoses while the engine is running, however mine will stay running without any of those things in place. Does anybody know why that would be? I recently replaced the pcv valve to see if that was it but that made no difference. I've been told vacuum leaks will cause this however my manifold vacuum readings are proper through the whole rpm range. Starting to think it's gotta be piston rings or something...
Doing my weekly check under the hood of my 82 ZX, and my valve cover PCV hose is splitting. I'm thinking over how the whole system works, and wondering if i'd get more performance if i removed the line completley, plugged the hole in the intake boot, and run a breather filter on the valve cover outlet port. I'm assuming i would get a bit more power since the engine will not be sucking in spent oily air, but what do you guys think?
