I recently purchase an 84 dodge b250 and yesterday on the interstate the engine got really loud. I popped the hood and noticed that something was missing off the front of the drivers side exhaust manifold and I can’t figure out what fell off. Any ideas?
I took the air pump and valve assembly off because they are not available anymore, Tap it and put a set screw in it. The other route of removing manifolds tapping and plugging the eight air /exhaust ports is time consuming
