Hey I was wondering if one of you guys could explain why my 312 ford thunderbird "Y" block is bending push rods? I know it is because the valve are sticking for some reason on that head but what is making them stick. I have driven the car about 7500 miles in the last 3 years with not as much use in the last year. It is stored in a dry heated garage year round. I had one bend this spring and I removed it and replaced it and then pulled the other valve cover and adjusted all the valves on both heads and then visually inspected the rocker arms which are very clean, no deposits. Then I treated all the valves to a double dose of mystery oil on two seperate days, put the whole thing together and gave it a tune up and reset the carb and timing. Just today I took it for a 10 mile drive to my shop, gave it some fresh 93 octane gas, and added another half quart of mystery oil to the crankcase oil. When I went to come home I started the bird and it bent another push rod. I limped it the 1 mile home and tore off the valve cover to discover a different one bent. How can I fix this problem. Besides carry extra push rods? Thanks for any help you can give. Randy
