Troy,

I have a problem with the pushrod cover O-rings moving out of their seats. Have replaced the O-rings and made sure to fit them properly, but they still tend to get out of position causing the engine to draw air/lean. Perhaps possible glue a piece of alu tube on the pushrod covers to increase the surface area in contact with the O-ring, or is there another fix?
