We had an E30 328i w/ 5spd come in our shop one day, complaint was, he was driving and all of a sudden a terrible clatter and died. Well it seemed to crank over with a bit of a limp but it sounded like it had good compression and wanted to run. Looked in the oil cap, cam was turning, had spark, had fuel just flooded a bit. I gave it a shot of brake clean and it fired up. It was making a nice knocking sound, and running rough shut it off. and there was a nice oil puddle under it. I then found it had lost the oil pump drive gear and cover. (where a conventional distributor goes in a euro M20) Everything looked undamaged what i could see. Poped a couple of used ones in and now it had oil pressure but still knocking. We figured it prolly spun a bearing since it lost the oil pump for who knows how long. Dropped the oil pan.....WHOLLY CRAP! A whole connecting rod was laying in the oil pan! The piston was in a ton of pieces, wrist pin still with the rod. Bearing even looked ok cept for a couple of dings. A rod cap bolt came out and it snapped the other. Then the crank must have whacked the free rod and took out the piston and poped the oil pump drive! All that happened and it still ran! Another we had a kid mis-shifted it and whacked the valves and it snapped one of the exhaust valve heads off, kept driving brought it to us. Pulled the head (was stuck to the block) and found the most unbeliveably hammered piston/combustion chamber ive ever seen. It eventually slammed the valve head through the piston top sideways where we found it. Still ran....
Very tough engines!
