Bank 1 Exhaust Camshaft Bolt Stuck (Really!)

[HelloImRob]

So the bank 1 exhaust cam bolt is stuck (4.4 M62tu), and when I say stuck I mean so stuck that a 6ft cheater bar won't budge it, in fact I've turned the actual sprocket somehow without budging the bolt. Now this is quite annoying as I'm almost done with the job but that last bolt won't let me rebuild that VANOS unit, being that the whole job would be rendered useless and the amount of money I've spent would have gone to nothing

Now, I understand that I can not use heat because 1, aluminium block, 2, camshaft is hardened metal which would be catastrophic to heat thus causing excessive wear on the camshaft.

Please help

I'll add I put AeroKroil everyday three-four times a day for a week and tried an impact gun. Before anyone asks, yes, I am going left-hand thread.

Hey, ever figure this out? I've encountered the same issue. I sprayed penetrating fluid on it this morning and will use my impact gun later, but I've already tried the cheater pipe and it is definitely stuck!

It's not reverse thread for some reason
