cracked lower case
« on: July 23, 2016, 07:42:40 AM »
 I have a 75 400f. I was tighting  the lower motor mount bolts and I cracked the case right on the oil gallery just below the oil filter. I am a welder so I'm going to try and weld it.  Has anybody else done this? What is the proper way to bolt the engine in? Does it matter which bolts you tighten first?

Shouldn't matter which bolts are tightened first. Upload a picture so we can see the damage. It could probably be TIG welded. I've heard of people welding the cases from chain damage and collisions. All it takes is a competent welder and cleanliness.

Please post pictures of the cracked case, with the motor still in the frame. Tightening the mounting bolts shouldn't have damaged the case, unless something was incorrectly assembled.
