Hi guys,



I am rebulding my engine and started with the rotors. I was following the knightsports rebuild video and when it came time to install the oil control seal springs i realized that instead of 2 blue big seal springs and 2 white big seal springs I have 4 big blue seal springs. Its the same with the small ones all are white. So I stopped and have ordered the missing parts.



But here is the confusion. Looking at the Knightsports rebuild video the guy installs the white ones on both the rotors on the gear faces and the blue ones on the non gear faces and on my rotors that i got from Mazdatrix there are blue marks also on the non gear faces of the rotors but in Atkins rebuild video the guy puts both the rotors side by side one with the gear face up and the other with the gear face down and installs all the blue ones and then the white ones on the other faces. Meaning one rotors gear face has the white oil control seal springs and the others gear face has blue oil control seal springs.



My car is a 99 spec FD.... who do I follow?



Thanks....

The springs are directional. As the rotor turns, the oil control rings drag on the irons, putting a force on the springs opposite direction. The springs are designed to lock into a groove on the rotor and the oil control ring. With the springs installed right, the oil control ring cannot be turned in the direction opposite to rotor rotation.



Spend a minute messing with a rotor and it should become apparent. The blue and white denote which side of the rotor they springs go on, so you should have a small white and a large white on one side of the rotor, and a small and large blue on the other. I dont remember offhand which color goes to the front or back though.

^ he is right follow this video its show u how to install them if the springs have no color code on them its pretty easy . good luck

There is also something done wrong in every how to guide and video out there. You do not actually line the spring up with the notch in the oil contol ring, it has to be just behind the notch, because as the spring gets compressed it gets longer and it will actually miss the notch when you compress the oil control ring into the rotor. In the FSM it shows it has to be in the notch, what it doesn't show is the technique to get it properly into the notch once the rings and rotor are half compressed into a assembled motor. So everyone thinks you just line it up and its A ok. Thats the problem with videos that are just people's misinterpretation of the poorly translated FSM.

I never see paint on springs in the field, so for every engine I've ever built, I visualize what the spring has to do. After I install the oil rings, I turn the rotor in my hand in the direction of rotation and make sure that the oil rings lock in place.



Even if you don't get it locked in, the ring will only spin around until it locks in, and then it's set. One or two rotations won't hurt a well lubricated O-ring. And if you don't need to lube the snot out of the O-rings to get the (heavy cursing) oil rings into the rotor, the O-rings are shot and the engine's going to smoke.

It will lock in if it spins, but by that time the o ring is usually stretched out if it didnt matter there would be no point in the line up procedure if the spring put itself into place with no other consequence.
