Hey guys, I took my FITV out to clean it today because I was having high idle when cold. So, I have it disassembled and cleaned... but I lost one of the 8mm bolts that hold that cap in place. Is the cap really necessary? I am looking at diagrams and it looks like no coolant actually flows through that side, right? Should I just leave the cap off, or buy a new bolt to replace it? A part number isn't listed for those bolts on acuraautomotiveparts... and I can't find the specs for it.

Also, is it normal for coolant to be dripping out the bottom of the throttle body while I had the FITV removed? I had it off for like an hour or so... and it seemed like I was losing a LOT of coolant.
