Topic: Those 4 small o-rings?

[Swoop]

The ones under the cam towers. I know that two go around the oil orifice thingies.....the other ones do not have holes in the head just a recess. What is their purpose?

They seem redundant....but I am sure there is a reason.

Thanks

Good question, I just did the same as you and fitted 2 new ones in the recesses, because that's how it was when i stripped it.

It's my understanding that it's the end of the oil path through the cam towers.  So the oil there is under pressure.  It would prevent leaking and a loss of pressure.
