Trying to remove the 4 bolts that hold on the crank shaft pulley, got the first 3 bolt out, went to get that last one and the bastard rounded out on me, i did the pb blaster over night, along with the tapping of the hex socket in, anyone have a good fix for this??

If you can't grab it with a quality vice-grip and get it to loosen.....use a die grinder to remove the head. Once the pulley then comes off, you should have enough room to use the vice grips to twist out the remains. If you still can't get it out at this point, just replace the gear....

Pound the next largest size bit into the head with a large hammer, and take it out.
Or, you can use a dremel and cut a slot through the bolt that a flat tip screwdriver with a large end will fit in, and use vice grips on the screw driver to turn it loose. Had good luck this way too.

If you could pound that next largest one in possibly a SAE instead of metric socket bit and use an impact to reverse it that usually helps. You hate to but sometimes an air hammer/chisel is the answer.

Also a 12mm 12 point socket will pound onto the bolt head and bite enough to get it off. Works almost every time.

i use an air chisel and try to catch it on an angle, the vibration usually helps break them loose! just don't slip off!

Not ARP but I got them. Also, in stainless, but I am pretty sure that there are a couple different crank pullies and bolt lengths. No bother to me, I should have all in stock at work.

Yes there should be different lengths.. fwiw, atleast four.. single v-belt (alt and wp), double v (alt/wp and ps/ac), serp belt, serp belt with v belt (wp, ps,).
If they took their old bolt out and got the measurements to you Lucas, would you be able to get them out to people

VW themselves make an upgraded version of these bolts with increased hardness etc... TDI's use 'em but they'd retro-fit. Most TDI timing belt kits come with the upgraded bolts.. since as you're finding out the old ones can be a pain.
I use anti-seize on 'em when I install 'em... some folks use locktite.

Awhile ago I posted about these little beauties: Craftsman female extractors (or easy-outs). Have a search on my username. They're cheap, come in many sizes now and are also known to save mass quantities of skin, analgaesics & beer
