I got it as a project and was wondering what could be causing it to blow a significant amount of air out of the intake?

Thanks

Is it from the EGR?

If it's blowing air out the CAC intake side then my bet is some or all of your rockers are trashed and the engine is likely out of time. The somewhat good news is if the engine is out of time the rockers are designed to self destruct rather than destroying pistons and valves.

I'd strongly recommend no running of the engine until you can pull the valve cover and check the rockers.

If they are toast a full set of 16 rockers and lifters can be had for, IIRC, $500-850 depending on where you shop around. Some have had decent luck sourcing from across the pond. The install is a doable DIY project but you will need the timing tools including something to hold the cams in place while removing/reinstalling the cam bolts as the cam pins won't stand the torque.

That engine is not healthy. Start by pulling the intake to check the rockers and valve height. It seems like an intake valve is stuck partially open. Too much running like that will eventually lead to a dropped valve in the piston.

That is very similar to the noises my Jeep was making. I just posted a video of the damage my Rockers suffered.

Get ready to take off more stuff and go to the Valve Cover/Intake manifold.

Yep that's it...Plan on replacing all the rockers & lifters. @103k has the timing belt ever changed?
