    Fixable or not?

    The flywheel on my 94 Deville Concours broke a few months ago. While it was in for repairs, the mechanic told me that the broken flywheel cracked my block, right near the oil pan, so now it drips oil when the engine is running. My first thought was to just buy a reman or used engine, but I was wondering if you guys would know if its possible to fix the area by welding it?

    Would I be better just buying another block, and if so, what are the prices I should expect for a used or remaned engine? Thanks for any help

    Aluminum is very hard to weld. It is porous, which means that when it comes into contact with stuff like oil, it will soak some of it up. This means that you'll never be able to get the welding surface perfectly clean. So basically what I'm saying is that the weld will look like bird crap and it will be hard to get good penetration with it. I'm not saying that it is impossible to repair it by welding it, just that it would be hard...
