I suppose it's possible....as is anything. I am a bit concerned about just sticking a bolt in it and hoping that the silicone actually seals it up again. Once the cured silicone is ripped apart, it's no good. You can try it though!
I'll send you a bolt (you may have to send me your address again  ) but I can ship it Monday.On edit: The oil that I'm noticing in the pictures is pretty common of loose clamps on the orange hoses from the "y" into the plenum. I've fixed a couple "rear main seal leaks" just by tightening those clamps.

Thanks for all the help Cody. Really, if you can just tell me the particulars of the bolt then I will just go to the autoparts store and get one. They should have it, right?
I will recheck the clamp on the orange boots tomorrow. Thanks again.

The bolt is a 8mmX 1.25 and is 5/8 long.
The bolt that was suppose to be in there looks like this.  IIRC it was for the ground wire that went to your AIH. On edit it looks like the ground wire is still there but it doesn't look like it is hooked up.....or is it? Sorry but I am with Cody on this one.

The AIH was removed when we installed my gauges. I didn't actually do it, but my friend did. That may be when the bolt was loosened or something. My boost gauge plugs into an AIH delete plug.

On your oil leak....
Since you have an 03, check the two high pressure oil hose fittings that connect to the left side of the HPOP. The O-ring on those fitting can fail(especially on 02's and 03's), and can cause a valley/rearmain appearence oil leak. It can be tough to see, but it will appear to have a washed down look to it, just under each of the two fittings. You can't quite see the HPOP in your pictures.... On your bolt, I'll bet its in the Valley still, look around and fish around with a magnet. You'll probably find it.

Alright, so I haven't had time to build a leak detector, but I had a few minutes this morning so I had the wife do a brake stand and run the truck up to about 2500rpm and 15psi of boost. I put some soapy water around the hole and there was a tad bit of bubbling, not much really. But then I put my finger over the hole and it was a steady flow of a good amount of air, and it directly correllated to the boost and rpm. When she let off the pedal, the airflow out of the hole went away. So, what do you guys think now? I would think I found my problem and need to plug the hole to fix it. But I wanted to keep y'all in the loop and get your input.

Put a bolt in it. If you felt air coming out of the bolt hole, then by all means, plug that bad boy up with a new bolt!!
I am wondering HOW you are getting air out of the bolt hole as both pairs of heads I have here have blind holes in that location. Maybe the casting is different or something. Regardless, that is definitely an issue!
