Question
I own a 3.1 ltr 1991 olds cutlass. I have changed my wtr pump twice with no
problems. But this time some of the impeller bolts either won't line up or will not
start. I think that at least two of them have stripped the alum housing. How can i
make this work w/o replacing the front cover? Help Philly

Answer
Phil,
  Permatex makes a product to repair threads. It is part number 81668. Sells for about $8.00. It is like an epoxy but you put a "release" agent on the bolt. You put the epoxy in the hole, screw in the bolt and let it dry. Remove the bolt and clean the threads. It states in the catalog it is designed for timing covers and water pumps. The other option is a kit from Heli-Coil but not knowing the thread size and pitch, I can't give you the part number. Sorry.
  ANY parts store, worth it salt can help you. If they can't help you, get back with me. Good luck.. Thank you for your question..
