Iv'e read a lot about the starter problems here but have not read about adding the drainage hole, even tho it was recommended to Dealers by GM way back in '92.
Just sayin, if you have to do the job, maybe you should follow GM's recommendations on how to fix the known problem.

It sounds like a worthwhile mod, to do while you're in there, even if the original hole is clear. Thanks for sharing (of course, I'll never remember this until right after the next time I put the plenum back on).
