I have always had a policy that when I have a motor out, I drop the oil pan, clean it, and replace the oil pump and timing cover seal. I got lazy one time and went with the old one............guess what went bad in a little while and I had to change in the car ? I broke my own rule, and it bit me.

As Shawnlee said, it is so much easier to do while out, and these are meant to be one time covers. To paraphrase Dirty Harry, "how lucky do you feel ?" For the $ 50.00, do you really want to gamble?

BTW, I just replaced the plastic one on my '99 Vortec with a chrome timing cover off of an earlier model Chevy. Summit said it would work, and it seemed to go on ok.
