Little help?
 
I've posted a couple threads already on this question and NO ONE can answer me, so I'll attempt to make it more simple.

I'll post a pic of my throttle body from the front, and will someone else please post a pic of theirs? It's an SE, and I want to look at someone elses car to make sure I have this oil metering pump connector rod thing put on right.

It's one of two things keeping my car off the road and that's not cool.

The OMP control rod is attached to a brass connector which is at the front (of the car) side of the main throttle butterfly rod. The OMP rod attachment point is on a spring mount, and when in correct position, this mount should be on the driver's side of the throttle plate rod that the butterflies are attached to.

Once you know this is on the correct side of the butterfly rod, then the 90 degree bend is inserted FROM the driver's side TOWARD the passenger side, followed by the small washer, and lastly the cotter pin. When this is all installed, you should be able to lift up on the brass connector, which will pull the rod upward, which will rotate the lever on the OMP, and hence, pump more oil into the oil lines leading to your intake system. This should move very easily, and if you feel binding, make sure that the OMP control rod isn't binding against the small coolant lines leading from the back of the water pump to the thermal pellet, or on the wiring harness that's located very close there.

The OMP rod can only really be installed one way without binding, so if you're feeling some resistance when you try to pull the rod up, you may not have it connected right. I don't have a camera with me to take a picture, but if you post one of your engine bay, I can help you to get this hooked up right.

Don't drive the car until you have the OMP connecting rod hooked up right - unless you're premixing...

OK here's a pic. This IS installed right, is it not?

Another pic. When disconnected, the rod has very free movement. What could I possibly be doing wrong?

On more picture. I reinstalled everything after doing the throttle body mod that JIMMY54 has done. Is there anywhere I could have gone wrong while reinstalling the throttle body that would affect this rod?

All 3 of your pictures are right in how you've setup the OMP control rod. The only thing that I don't see in your pictures is the small washer that goes on the end of the rod after it's been inserted through the connector, followed by the cotter pin.

The cotter pin is to ensure that the rod doesn't come out of the connector, so make sure that you get this pinned somehow, even if you use a paperclip until you can find the right cotter pin size.

As long as you've got this installed correctly, and the OMP pump is working, you shouldn't have to worry about anything else. Do you have some specific concerns about how this is working?

My OMP control rod, when removed from the throttle, moves VERY freely, but if you trace this down to the OMP itself, you'll see that it's operating a small arm on the front of the pump, that's it. It should not have a whole lot of tension against it - it should move freely when you pull it up by hand otherwise, your throttle linkage will be fighting that tension when you step on it.

Reply back if further questions - but you've got it right.

I figured out what it is. Went under the car this weekend and found the connector underneath the car. There is a slight bend in the rod and I think I must have pushed the rod down and is now stuck because of the bend. I'm sure the bend is supposed to be there, but I can't get it back. Oh well, in short, I figured my problem out. Thanks.

Now I just have to fix it.
