I had a fuel delivery problem with my 86’ 635csi. I pretty much narrowed it down to clogged fuel injector(s). One of them was clogged alright. I found this in the top of the #2 cylinder injector. The problem is I can’t figure out where it came from. I replaced the fuel pressure regulator since it seems the most likely place from this to have come from.
Any one else ever see one before? Its about 3/16" long, and 1/8" diameter.
