That is my worst case scenario. This engine was purchased through Checker Auto Parts in July, 2003 and sat covered in my garage until installation in summer, 2011. So the 12 month warranty came and went before it went a mile. I had the entire rocker assembly loosened while in storage so the valve springs wouldn't become fatigued. I've been trying the Band-Aid patches to rule them out before disassembling a new engine. I've been HOPING that these valves would loosen up with some miles on them but haven't seen any improvement yet. I'm going to try another Band-Aid and add some Marvel Mystery Oil to the gas. What the heck!
