With that said, I've broken these loose with very beefy electric impacts, although it'll vary a bit engine from engine.
90 psi is all ive got unfortunately, that gun cost me 400 and the Milwaukee would cost me about 600 with battery, I might brace my engine stand and give it one more shot when my shoulder has healed from the weekends cranking this thing lol

I had the same problem at my last timing belt job. This was a bolt I had installed with the same air impact that now wouldn't remove it. An Ingersoll Rand crank bolt socket zipped it right off.

You need to crank the air up. Air tools are worthless at 90psi.

Crank up the regulator. Watch the gauge drop when you pull the trigger I bet youre only seeing something like 60# at the gun. Just crank up the pressure youre not going to hurt the gun. It should pop right off.

Agreed with the above. If you don't have a high pressure (150+ psi) air source with at least a 5+ gallon tank, then a beefy electric impact will do the trick. I've never met a bolt that has not come off using this impact. Picked it up last year and never looked back. Max break away is actually 1200 ft/lbs.

My compressor runs at 130psi. I crank it all the way up to remove crank bolts and axle nuts. I otherwise run the gun at 90psi, just to be on the safe side (harbor freight Earthquake = questionable quality )

Agreed have that as well and it is awesome.
