Finally had a chance to drop off the pipe to get the flange welded on for the BOV. I took the pipe off last night then cut off the old flange and dropped it off a local shop this morning. Picked it up tonight and threw on the new BOV. I still have to adjust the spring, however everything seems to work fine. Hopefully tomorrow morning I can run over to the shop and get my o2 bung welded on for the wideband.
As you can see the old BOV was plastic and quite small…

New and Old up close…

Below is the new flange welded on….



Figured I’d jot down some of my notes on part numbers for my Mustang, which pretty much applies to any Foxbody Mustang from 1987 to 1993 with a 302 / 5.0. I’ll be updating this post as I go through what I ordered / need.
