Ok, just because some of you might need a good laugh and others have done it before. It has been a long time since this happened to me! Just finished reassembling my r53; did supercharger oil change, put on new idler, belt tensioner, thermostat, water pump, crank sensor seal, hoses, 15% pulley, cooler plugs, trans oil changed again...and just about to put the bumper skin on when I see....a bolt. It's a 13mm head with a shoulder before the threads; and it's only one bolt but I can't seem to remember what it went to. It is a clean bolt, so I know it wasn't behind the s/c or anywhere there, as everything was covered in blacknastygoo. Anybody recognize this bolt? It is easier to ask than to start taking apart again. I was just bragging to myself; car started/ran great/didn't leak/didn't rattle. And then this bolt! Thanks for any help!

 

looks like the bolt that holds on the black plastic air horn.. it goes onto the SC intake at the bottom of the SC. I just reinstalled that one on my clutch job

Phil, do you mean the one right on the front of the air horn/intake, where the black plastic has a slotted kind of hole and a bolt goes into the supercharger to hold the air horn to it? if so, nope it isn't that one-too big, and I know I put that one back. It's also too clean to be from there, as everything there was black. Any other thoughts?

 

Got all the thermostat housing screws in ? also seems to me there was a wire harness like bracket near the thermostat that may have had a bolt like that holding it down.
