Required replacement when OH
This is the O-ring that is installed on the outer circumference of the valve seat. If the O-ring is worn out, it will cause unstable oil level and overflow, so it should be replaced at the time of regular overhaul.
When removing the valve seat, use thin pliers to pull out the valve seat without unnecessary force.
After cleaning the Valve seat, carefully press-fit it with lubricant and replace it as if you were press-fitting the Valve seat by tightening the Screw.

It's still an OEM Product
I guess I shouldn't have used the Universal Product, but I didn't want to be stingy, and the OEM Product was perfect. View detail
This is a regular replacement product.
This is a regular replacement product.
But I haven't replaced it in about 7 years (sweat).
If this O-ring is damaged, a decrease in the density of the Throw region is said to occur.
When we were struggling with Setting, it was pointed out to us and we decided to replace it.
In my case, this was not the direct cause of the problem, but it is a component that should be addressed as a regular replacement.
I would like to replace it regularly with Rip seal and various Screw O-rings in the future.

It goes well
I thought it was about Overhaul and prepared it.. Leaks from Valve seat will not be able to get out of Idle as it will be Idling. It is also good when fitting in. The O-ring that I removed was flattened. View detail
