Help! Mystery bolt from head gasket job

[carlcad]

I'm hoping someone can identify this bolt. I'm replacing the head gaskets on my '97 4runner with the 5vz engine and I have made the ultimate rookie mistake. I've got an extra bolt. Somehow this bolt found it's way into the ziplock bag with my alternator nuts and bolts. I do not think it goes to the alternator and I've gone through the removal process in the service manual and can't find any place where this bolt is shown. It's an m8x90.

Is it the adjuster screw you use to tighten the belt? It's only an 8 so it's not going to hold much strength compared to one holding the alternator on or the head down.

 

[carlcad]

No, it's not the adjuster. It's only threaded at the end, so it slides deep into something before it starts to screw in.

 

[shootmymime]

What side of the head did you replace?

Are you sure it's not the alt bolt? Or the power steering bolt?

 

[carlcad]

I replaced both head gaskets, so I worked all over the engine. It's not part of the alternator, because I have that installed. I also checked the A/C and power steering mounts and I have all the bolts for those. It's smaller than any of those bolts also. It's only an m8 and all of the bolts that hold on anything big like a pump or compressor are larger diameter.

There were a few of bolts that size on the intake. I believe right near the throttle body.

 

[carlcad]

Yep, that was it. It was the middle bolt that holds the air intake chamber onto the intake manifold. One night the shop gremlins must have switched bags on me. That's what I get for taking two weeks to finish the job!!
Thanks everyone

Tip: Next time use gallon zip lock bags and a sharpie to label them.

Glad it all worked out!
