As Geo, I have also made some good gaskets from stock sheet material. There are a lot of good products out there, unfortunately, ya gotta go looking and compare. Also, I don't use the oil pan gaskets from any of the big vendors. I have found that oil pan gaskets available from NAPA are the best quality. Remember, most gaskets are only a vehicle for you sealant, it's not really the gasket that seals. That's why, when I use Permatex Aviation, I will saturate the gasket thoroughly, with several applications, and seldom get a leak. The key word here is seldom.
