Check for spark around the boots and where they plug into the cap. Next time it comes time to replace them try the AC Delco Part No. 9608U $62.99. These wire last a long time. They are 8MM wires with a lifetime warranty too. Order them online and pickup at the store for a 20% off.
Plug wires are brand new and there is no visible sparking.
I just did a running valve adjustment using some old steel cut out covers. The rockers are definately getting oil at idle and when the engine is reved.
This issue is stumping the hell out of me.
