Hey, my name is Zack Glacken, I bought Kevin Miller's old duramax and just had an injector stick open and mess up my piston, Thomas Lilly recommended me to talk to you about gettin it fixed. So, I wanted to see if you would be interested in working on it? The injector has already been fixed and put back in, I checked the compression on the cylinders and #4 has no compression. I was told that I have a hole in my piston.
