I have a 91 325i with a m42 swapped in it. It has a cop conversion. This weekend I replaced the valve cover gasket. One of the studs would not make torque spec but it was only one and all the others torqued to spec. I waited a day before I tried to start it and it started to miss on #4 while I was warming it up in the garage. I held my and and ear by the suspect stud but didn't notice and vaccum , all of a sudden the #4 coil pack puked black goop out of the side and started to smoke like crazy. I thought it was just a bad coil pack so I found two extra at the local yard. I got home and tried swapping them around and managed to melt two more coil packs. I tried splicing in a different coil plug on number 4 and no change. I even tried swapping in a extra ecu and no change. The car has new plugs with the gasket change so I tried and old plug in #4 and still nothing. I know it's not firing because there is fuel on the plug. The coil is getting super hot so it has to be getting power right? I have no clue what to try next at this point please help!
