After a lot of dilly dallying and a major event (my wife passed away) I finally got some things done on this engine. I replaced the rod bearing after using fine emery cloth (tape) to remove a burr on the journal, the bearing material came off with almost no effort. The journal looked very shiny and clean. Put it back together and had the same knock. (No.1) Got some advice from Brandon314159, and swapped no.1 and no. 2 injectors. Same noise but I noticed something that I hadn't before-when I cracked the fuel line to no. 1 injector the engine sped up, not a great deal but noticeably. It missed and shook a little more than normal but it did run faster. (probably 20 or 30 rpm). My first thoughts are that the timing for no. 1 is off but the rest are OK. I don't know how the injection pump works so I don't know if this is feasable. Does anyone have any words of wisdom? Luckily I have the "D" to drive while I mess with this one.
