I got the spring off the exhaust valve on cylinder one of my 79 2F engine, but the only way I could get the valve seal off was to get a screwdriver under the lip of the seal and pop it off. When it came loose, it launched itself like a missile. I spent an hour looking for it, but have yet to find it.
I oiled up the valve stem and new seal, and put a straw over the stem and tried to seat the new seal, only to discover the metal base of the new seal won’t fit over the valve. Attempt #1: I put a deep socket just big enough to fit over the valve stem and pushed and then tapped on it, but destroyed the seal. Attempt #2 was just like the first attempt, except I put a flat washer on top of the seal and tapped on the washer instead of directly on the seal. Same result.
The seals are Toyota OEM part # 90913-02033. I have checked multiple sources, and they all list the part number as the correct seal. They were purchased from a Toyota dealer.
Any idea what the heck is going on?
Here is a picture of the seal.
