These were left over after exhaust manifold was replaced. M8 by about 40mm. Any ideas? Couldn't find anything. Runs ok now.

 

You are sure they are 8mm? Bolt head is what? What did you take off the intake when you pulled it?

 

I am going to say those look like something that go on the PS bracket where it connects back to the intake manifold.

 

Agree - looks like the power steering adjustment/bracket bolts.

 

They are too long for PS, which has all bolts in it. I even pulled the PS bracket off the manifold/waterpump completely. PS attaches with 3 different brackets. Big bracket that attaches to WP/IntMan, Small 3-bolt bracket to that, and the bracket that actually mounts to the pump, Pump-bracket. Big Bracket has 4 bolts; 2 on Waterpump and 2 on intake manifold. Pump bracket attaches to 3-bolt bracket with 2 bolts; the swivel at the top, and the slider at the bottom. I spent way too much time checking these, tapping holes, and die-ing bolts.

I'm not sure of head size. I was keeping all hardware in the airbox, so it's possible these were already in the airbox from a previous job.

 

Are they for the air box? Arent there 2 that are in the bottom of it? Its been a while since I have worked on a Jeep so I am just guessing!

 

Negative. the airbox bolts are shorter and installed.
