Engine + Driveline / Re: Coil packs melting

« on: August 15, 2016, 12:23:40 AM »

I seem to have fixed it by re soldering the power wire making sure to trim back the shield part of the wire to avoid shorting. I bought a multi meter to do continuity but re soldering seemed to fix it. Thanks for the pin out locations I was searching forever!! I'm still kind of scared of fire, should I try to run test still even though it's running fine?

Engine + Driveline / Coil packs melting

« on: August 07, 2016, 10:25:07 PM »

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!

Engine + Driveline / Valve cover gasket leak

« on: January 30, 2016, 12:25:50 PM »

My car weeps oil from the oil fill cap and seems to be seeping up from the plug wells on to the to of th vc..? I will try to post a pic. Symptoms are oil consumption tapping at cold start, intermediate tapping under load and low rpm, and Wet plugs. Before I just change the gasket , it sounds like I have a positive pressure problem pushing the oil, otherwise I can't see how I could have oil marks on top of the vc. Car runs smooth when warm except for the intermittent tapping described above. It does not smoke at start up, but under a hard pull I have noticed a small amount at night if someone is behind me with there headlights on. Can't see any at day time. Does this sound like worn ring blow by, or possibly a simple fix of some breather hoses/ valves? When I bought the car last year po had receipts with labor of all hoses replaced.
