I know it's been on here a million times but I went at it from a different angle. The spring in this pic had nothing stopping it from popping straight out of that opening. In fact when I removed the Cam chain tensioner the spring was almost popped out. If it comes out and there is no more tension on the ratchet, it's easy to predict what will happen...kaboom. So I took it apart and drilled a recess into that part so the spring is captured and has nowhere to go. $20 says that spring coming out is responsible for all the engine failures. Hopefully I just saved myself $450. We shall see.
