Changing out the OPDA
How to "clock". Very important.
This was this initial "how to". I include it so you can see some of the details of removal/installation.
Removing the air cleaner housing makes life a bit easier.
1.Take photos. Install position is not critical. Alignment between OPDA and engine timing IS critical.
2.Remove cap. T20 torx
4.Insert pin from new unit OR insert something similar like a small screwdriver to keep the alignment.
5.Unplug the wiring connector. Slide red tab. Then press the standard release mechanism.
6.Unbolt retainer with 1/2" wrench. Set bolt and retainer clip aside.
7.Lift OPDA. It WILL rotate counterclockwise as you lift it. Don't fight it. That's the design. It turns less than a 1/4 turn. Note OPDA housing alignment in relation to engine.
8.Find the gasket.
Going to be away for a while? Cover the hole in the engine with a rag.
1.Make sure pin is in place in the housing. Put the gasket over the hole or find a way to adhere it to the OPDA.
2.Reinstall is just the reverse of the removal. Expect the rotation--clockwise this time. If the unit does not slide/rotate EASILY into position (remember that first photo?) the oil pump slot needs some adjusting. Use a large flat blade screw driver to turn it. Small increments. It may take a couple of tries to get back into alignment. When you do get the oil pump slot in the correct position, the OPDA will almost drop into place. Frequently, no fiddling will be required. But it happens (see video #2.)
3.Double check that the OPDA is fully seated then reinstall that damn retainer. It's a pain but it will go. Tighten the bolt but don't go gorilla on it.
4.Pull the pin.
5.Reinstall the cap.
6.Reconnect the wiring. The plug is tight. Make sure it's connected. Slide the red tab.
Reinstall air cleaner housing, if you removed it.
