It did this about 7 years ago and i remembered speaking with a mechanic and he looked on his forom. It HAS to be a factory cap. Aftermarket one blow right thru.

Ac Delco and Duralast distributor caps are made by the same co.. Wells, after 3- Duralast caps, put a Delco on, that's when I found out same company makes both. So, now we wait, If after a heavy rain and no spark...I just read a service bulletin regarding the very issue, screens in distributor have to be popped out, told dealership this and they blew me off. As I said now we wait.....
