i just bought an evo IX and it came with a greddy rs bov. i know they suck and i read up about them. today when i looked under the hood and i noticed that the washer nut on the top of the bov was gone. i was wondering: 1. is this going to cause a problem? 2. should the setting be on hard or soft? currently its on hard..

 

Get the stocker from wherever you bought the IX.

no, toyota wont be able to help you much. go to a mitsu dealer or order a stock 9 bov or jdm mr bov
