BOLT LOOSE! HELP!!?

[ddgrave321]

Yeah so I took my 240 last night for an evening stroll. just a drive to the gas station and not even using up the turbo. I then heard a clunk in my hood and heard it fall out. Pulled to the side and walked back, and what I found is a bolt (pics below) the thing was hot! I mean this thing took a good few min to cool down so I know its from my engine.

Looked under and didnt notice anything dripping.. tried hard to find where it came of the engine and the only thing i saw was the turbo was missing a bolt. Tried that place and it seems like it didnt fit..

only thing I can think of was maybe its a bolt from the transmission since it is giving me a headache with the clutch and crap..

so do any you guys know where this bolt might go? And today I notice that when i rev around 4-5k i hear like a pop under my car (not engine bay) maybe its something down there?



this looks like it might have broken of. smooth surface and a couple chip makes me think this bolt broke of


The word on top of the bolt reads as "A2 -- 70"

possibly a flywheel bolt but not too sure

Almost looks like a sway bar mount bolt. Check those, though I don't know why it would be super hot. What size is it? The head.

Thanks all for the suggestion guys. I wont get it into a lift till thursday but I def appreciate all of this. Ill make sure to check the places you guys recommended. And the Bolt head is somwhere like 1/2,12 mm

Length: its about an inch and a half. But like i said the bolt looks like the bottom was clean cut which broke of..

Looks like an exhaust bolt to me, I don't think Nissan bolts have those markings on them...

So i got the car on the lift and spent about an hour looking at everything and didnt find a thing.. being an exhaust bolt is the closest thing I found tho.

It def matched the exhaust bolt that was installed on the other ones. However I didnt find it anywhere that could fit and a place where it might have even came off of.

Like I said my car feels the same so IDk ..
