Bought this kit for my 2001 Toyota Avalon. I was there when a professional rocker cover gasket mechanic attempted to install a spark plug tube gasket. After repeated attempts to install the seal, as numerous videos on YouTube show, the seal did not start completely. There was no way he could put it on without damaging the seal. What happened to the first seal he tried to install. I was happy to have a spare Fel-Pro kit on hand. The pipe seals fit, with minimal tapping to set them in place.
