Ok I used ot have all my emissions equipment and I recently decided it was extra junk that I didn't need especially since there isn't anything driven from the belt. Just that weak motor and air tubes to leak ugly fumes everywehre and make my engine look ugly... I have shorty headers that had the fittings welded on but the air system has those ugly black spread out looking fittings up above the manifolds laying on their side and acting as a fitting between the metal portion of the system and the rubber hoses. After unscrewing this piece I am left with a large threaded male area. Does anyone know of anything that would work as a threaded female cap to thread onto this part to effectively block off these holes. (Until I can get some long tubes...) The part number shows on the picture and this is from a 95 camaro z-28 convertible 0bd1. I destroyed the other one of these removing it due to heat warp. I also stripped some of the threads on one of the fittings on the header.. Other then that I need a cap that threads on the exact size of what you see in the picture but capped off. I bet a ton of people have done this before. I already had egr blockoff plates. I had to leave that rear hose connected but put the block off in between. That dang egr is hard as heck to get at and a lot easier to get the blockoff plate back on. I think that some years had different sized threads for some of these fittings.. Just thought somone might have a 94-95 and have the same problem possibly... Thanks guys.
