I haven't noticed any oil leaking. Looking where the 1/8" hole appears on the case has not shown it's ugly self. My question is just how many of you with trucks like mine have this problem? A true ratio would be nice to see as opposed to worring about this problem. I'm hoping of course that I will put a million miles on mine without any problems at all, Huh.....

From what I've read here, most if not all will have it at sometime. Most seem to be on 60k miles and up. Just a matter of time I guess. GM quality once again.

For what it's worth I'm at 91k miles with no hole in the case yet, but I do have my fingers crossed!
