This is the Sump for the 6.3 M100 Engine .On the right front corner. Oil was leaking through the weld and the side of the pan was full of cracks. All were leaking.

The welds were very porous and leaking badly.

The easiest way to fix all of the cracks and bad welding was to cut the bottom off and make a whole new bottom and weld it in place.

The Engine was rolled over to get the Sump off and to replace the crank seals . The crank shaft had to come out ,but bearing damage was revealed.

Careful measuring of the crank revealed it to be free of any damage  so will be cleaned and reinstalled.

The Bores are ok and only needed a light hone to restore the crosshatch pattern. The rings are worn and will be replaced.
