downpipe to 02 housing bolt?

although, i would have expected this bolt to be a bit rusty...it looks every similar though..

 

it could be a random bolt from sombodies else's car u ran over...

 

This would be ideal but I doubt it.... I have the worst of luck.

 

theres no way... it doesnt have the "built on washer"...

any results on your findings yet?

 

I'm actually at work right now but I'll check the bolt size when I get home tomorrow and I'll try to look under the car. I can't get it to a lift till thursday.

 

you know finding the measurements for the bolt ie .85 pitch, w/ length will help

 

I know the bolt has an 8 on the head

 

i think that 8 just means its grade 8? Figure out what socket size fits on it for starters. 14mm 17mmm etc...

Good luck. I hate it when this happens, well this and when you lose a bolt or washer or something. Never fails no matter how simple a job something will fall down into the engine bay making my 15 min job an hour job

Good luck!

 

No such thing as a Grade "8" Metric bolt.

Metric grades are generally 5.8, 8.8, 9.8, 10.9, 12.9.

Knowing what socket size it takes is a huge help because most of us who work on our cars regularly know what whench sizes go where for which bolts.

 

Judging by how clean it looks i would say upper engine bay somewhere...bottom side usually picks up road grime, brake dust, etc.

Otherwise go with what 4ws said and check every thing u have recently removed/loosened for mods

I dont know if ur motor mounts were direct replacements or not but it could be an extra not needed for the new that u dropped during disassembly...longshot i kno

 

Good call! Thanks for the correction.

and +1 on it prob being from upper engine bay because being such a clean bolt.

 

I found were the bolt came from. It was in plain sight the whole time! I was just overlooking it. It was off the cross member. Thanks for all the help!

 

Oh shoot, it was a subframe (Cross member) bolt!!

Do I win a prize?

 

BZ and a Job Well Done!
Thanks
