Just a couple of comments, Susie.
1) When you anneal copper you make it softer. It fills in gaps pretty well if the block is rough in the surface between the oil pump and the block. Does a nice job of sealing.
2) Oil pumps are torqued to a given value on the block typically 30 ft/lbs
Pontiac developed that torque spec (assuming the paper gasket) for the oil pump retention bolts. It has worked for many years.
3) What does the company that sells the copper gaskets recommend for a torque spec with their copper gaskets. Just wondering.
4) How many times can you torque that copper gasket?
(If the Pontiac paper gasket is not torn you can put the oil pump right back on the block, torque it to 30 ft lbs and it will seal just fine again for another 50,000 miles.)
That being said the paper gaskets are cheap, the copper gaskets ??? never looked at buying one.
Maybe you can help me out of these questions Susie, because you have looked at their product.
