How do you genius know if your engines were correctly assembled so that your auxiliary ports function ?_When you service those auxiliary valves to be certain they rotate & open, how can you be certain that you have maintained their correct timing ?____ Your beloved Mazda factory permits you to install the auxiliary port valve Shaft if the valve is correctly positioned, or 180 degrees incorrecty positioned.
Respectfully, John Earl Robertson.

you can tell if it goes fast above 4000rpm or not

well you can always take the hood off and run next to the car to see if they move at 4k rpm?

Or put a little dab of grease on the rods that move and see if the grease gets smeared when you drive your car hard.

Or a zip tie on the shaft will also work as a tell tale.

Guys, he is asking how that you know the sleeves are installed correctly, not how to tell if they are working. I had this same problem when I rebuilt my SE.

When you put the sleeves in, you are not sure if they are correct or 180 degrees out. It seems from my experience that if the sleeve can easily attach to the accuator and go back together, you probably have it right. I positioned mine and rotated them in the direction that the accuator moves them to see if they ended up in the correct spot. The opening in each sleeve should face towards the center part of the engine when accuated. The manual does mention something about lining the rod in the sleeve with a mark on the intake gasket, but I didn't see one.

GSL-SE Addict, Spinner. Thank you for comprehending my question. Your perception & analysis are superb. You quoted the workshop manuals instructions to me for installing those auxiliary valves in a partially disassembled engine. Anyone can do that blindfolded. Again, I present my question:How can normal humans devoid of x-ray vision, know if those sleeve valves are correctly Positioned, or, 180 degrees wrongly positioned. in an assembled engine ?________The actuating rod will easily engage & rotate a 180 degrees wrongly positioned sleeve valve. Keeping those bores clean so you will enjoy a 6 ports engine, is intensive maintainence. If one is distractraced while performing that onerous chore, one can suffer a malforming engine. 73's. W4DFW.

The pin on the sleeve (where the actuator attaches) one end is wider than the other....

I believe that the wide end of the pin is pointed down. Max7 has a pic of this, he helped me with the same question some time ago.

JIMMY54, thank you. you are describing what you see during reassembly. You cannot see any of what you describe in an assembled engine. So, in an assembled engine, which of the two positions, right or wrong, do you position the sleeve valves prior to installing the rod which rotates them ?________ I don't want to do a days work every time I unseize those sleeve valves which must be kept clean for them to rotate freely. Thank you for trying to help me. 73's W4DFW.
