Very interesting :hhmm:
I will have to check this out, if my 62 gets any quicker I wont be missing my sti
 
I made the adjustment on my 92 FJ80. It needed a few turns with the screwdriver to tighten it down.

After driving it around home, it seemed to have better low end torque. The true test will be when I head over Snoqualmie Pass (hopefully tomorrow). I have a good baseline from traveling there last week (13.4 mpg gallon from Federal Way to Ellensburg, WA).

I just checked mine again last night while I was gassing up, just for s***s and giggles (and to distract myself from the assrape being counted up on the pump) and it was coming out again. So I snugged it down again and noticed the same improvement in power. I figure it's worth checking every time you gas up, just to make sure it's still good to go.

I can't wait to drive across HWY2 and see what kind of economy I get out of it.
 
where exactly? got a zoomed out pic?

Look straight down over your engine, all the way to the rear, you'll see the plastic cap (or if lost, see the picture in the first post).

You can pop it off with your fingers.

The Napa one I bought has a rivet, not a screw. I wonder why there is a screw there? Maybe manufacturing limitations at the time? Who knows.

EDIT:
I have not swapped them out yet, I am getting a feel for the power I have and I wanted to see if there was a power increase with the new part. Plus, I am going to pick up a cheap wrench for modification to change this part out.

Ooooh, good idea. Let me know what you end up with. My screw keeps wanting to work its way out. I'm not sure if it's supposed to work its way loose or not, but I'm thinking not. Methinks snugging it down and putting a small bead of JB Weld on it might help solve this little issue :D
 
I don't see that this thread in the stickies? Can we get it in there?

And, my screw won't thread back in for some reason...should I just get a new dampener and replace it?

Did you make sure you're not cross-threading the screw? Also remember it has that little rubber O ring on it, so when it tightens down, it won't simply just stop as i hits metal. It'll compress the O ring.

I'll put it in there. I havne't looked at my engine bay yet to see where the thing is, but will someone snap a zommed out pic of it for postarity?
 
Its about right where the red arrow is. Near the very back. Its not really on the drivers side or passenger side, kinda right in the middle. You can see it best from the passenger side, but get to it best on the drivers side.

Hope this helps.



*edit* I also checked mine, and the cap was there, but the screw was loose. Will tighten it and check out how my gas mileage is.

My screw is all the way out. I tried for...more than 30 minutes to get it started, but they thread just won't catch for some reason. It's in a touch spot...I guess I could remove the dampener, try to get the screw in, then put the same one back in.
 
:hhmm: Are you sure that engine has one?

BTW, a dampener makes something wet...a damper absorbs impacts, pulsations, etc.:D
 
I checked mine. The screw was in place but I was able to tighten it down a little. I will see if it make adifferance in power and mileage.

this one doesnt it was just a picture to show the location haha:doh:
 
Does anyone know if you can get the screw without buying the whole damper?

I'm sure you can find a metric machine screw that'll fit, and put a small O-ring on it. That'd do the trick. I'd be surprised if you can order just the screw from Toyota though.
 
Mine turned about 1.5 revolutions. My grey cap is gone. New coil pack and tight screw, hope I'll see a MPG improvement.
