So I had a customer tow in his 2010 750LI. Now he said it was running rough and the reduced power light was on. The tow truck driver, however said it was not running when he got there and there was copious amounts of oil under the vehicle.
When we put it up in the air this is what we found.
Number 7 rod broken. It hit the oil pump so hard the oil pump was pushed through the oil pan. then the remainder of the rod was punched through the left side of the block.
.........really nice pics of new block and blahblahblah.....
And although it's a sexy thing the engine costs 27650.00 for the part alone.
All in all it will cost about 35grand to get it running again.........
Anyway this one is under warranty. The #7 injector on this DI engine hung open and it filled the cyl with fuel causing hydrolock. There was a pint of fuel in the intake on the right bank.
