Hey, I just cleaned the IAB out... I used some Greased Lightning auto degreaser (works a heluva lot better than I thought it would, btw) and got out all the gunk. I thought I read somewhere that you're not supposed to be able to clean the IABs that are only one piece? -- Jason Hartberger, AT2(AW) USN USS Theodore Roosevelt CVN-71 AIMD/IM-3 CASS
