Hi,
I keep reading about throttle plate screws coming loose. What type of epoxy are people using to secure the screw?
Is it as simple as putting a dab over the head of the screw?
Sorry if this seems like an obvious question, but it isn't something I want to get wrong!!![eek](https://www.miataturbo.net/images/smilies/eek3.gif)
Cheers

Well I make assumptions, but it is playing on my mind. The guy on here with the chopped up compressor wheel, and another post today on the Adaptronic forum showing an MX-5 with ingestion damage.
Are you saying it's only a problem if the screw has been removed before?
Thanks

Why? So the epoxy can go through the engine too when the throttle shaft breaks and sticks the throttle wide open?
Shameless plug for actual solution to actual problem

If you do epoxy it, make sure you prepare the surfaces correctly. At the bare minimum give everything a good wipe down with acetone or some other solvent that will flash off quickly.
Hysol e120hp is a good all purpose structural epoxy but you need to buy an applicator gun and mixing nozzles to use it.

From what I remember reading, all the epoxy really does is change the natural resonant frequency to move it away from whatever rpm/vibration is causing the shaft to break.
I have not done any searching, but has there actually been a case of a screw coming loose, but the shaft staying intact?

Damn that sucks Ian. Are you now running the Skunk2 item?
If so does the increased opening make the throttle really sensitive?
Out of interest I used to have a Jap import track car and it had a rubber damper fitted to the throttle body (OE), I wonder if this is relevant as the car had a slightly higher rev limit?
