A few weeks ago did an engine swap on my 2001 E46 325Ci. Had a professional mechanic who's very familiar with engine swaps and owns an E36 help me.
Have been driving the car happily for a few weeks. Last Friday put in half a tank of gas and parked in driveway that has a slight grade. Done this hundred of times before.
Came out, got in car, turned the key three times and started on forth. Always had started first try. Smelt gas and on getting out of car saw a fair amount of gas on concrete. Backed down driveway, parked on street.
The next day had car up on ramps looked underneath vehicle and under the hood, all appears good. No loose fittings, no splits or punctured hoses, no residue from spillage. As if nothing ever happened. Car drives fine, no trouble lights. No smell of gas.
If there wasn't a stain on road I would think I was dreaming. Anybody got any ideas.
