Group, We talk about engines not running right, rough idle and so on, the O Rings play a very dull and important roll. Often out of sight and neglected. I put together a kit some of the more popular O rings and vacuum gaskets in a kit on the web site. It will be supplied as shown. One of the most common over looked is the idle speed tube going into the bottom of the air flow meter. The seal isn't very tight, but that little O ring and keeper must fit snuggly. Most often it's hard or someone has put silicone all over the tube and hole to get a good fit. Maby the kit will help in finding or preventing a problem. If there is anything I left out that someone feels should be there, please let me know. It's on the front page and the hardware page. Some of the O ring pictures will be on the Reference page of Talk & View. John Hervey http://www.specialtauto.com/
