    As the title says. I would like to know the size of the ISC Motor gasket or o ring to replace it. If anyone knows where I can find one without ordering one online lemme know. Thank you.

    The one I have and measured has an O.D. of about 35mm and a thickness or cross-section of about 3.5mm, which makes the I.D. about 28mm.

    https://www.extremepsi.com/store/OEM-ISC-Idle-Speed-Control-O-Ring-Mitsubishi-Eclipse-90-99.html The part number I found was MD614417 but isnt currently made I believe.

    I see no reason to pay 7 bucks for a O ring plus shipping unless I had more stuff to order. What I did ordered a variety pack of Orings from a few different companies. I just used whatever fits. I have been using it for years without issues.
