I was trying to finish up doing the front reseal/tb/waterpump job on my 944 including all of the race/flanges, mylar seals, front main oil seal, oil pump gear, balance shaft rear o-rings on the balance shafts, and finally the cam tower reseal front/back along with the valve gasket.
I was using Clark's method of waking-up the bolt with my 10mm cheesehead socket, and had the wife hold the retaining collar.
I tried removing the cheesehead bolt from the front cam pulley and now after plenty of attempts, it's stripped. So my question is, anyone know how to remove the cheesehead now? I don't have any torches/fire, is there any hope, or am I SOL?
Can I remove the cam tower all in 1 piece and try to remove it off the engine?
I am open to any and all suggestions.
Thank much, phil.

Yes, you can pull the tower and remove it on the bench. Either way, however, it's surprisingly simple to drill the head off. Just use a bit slightly bigger than the shaft of the bolt. The stripped out head will center the bit, and the remains of the bolt will normally just turn out by hand. Use a shop vac or magnet to mind the metal shavings.

I think the hulk tightened down the cheesehead in the car currently. While trying to remove the cheesehead bolt I cried, laughed, prayed, had a hissy fit, mumbled some incantations, then finally came back to my senses and asked you guys for help.

I am ordering a new cheesehead set, the set I bought was cheap Performance Parts one's($17), and now I am paying for it with a stripped camshaft bolt.
I am going to pull the whole tower so I can get a drill bit in there and get to drilling.

Don't feel bad - those cam sprocket bolts strip quite easily. As has been suggested, you drill the head off with a drill bit that's just a little over the shank diameter of the bolt - this allows the head to separate from the shank. Once that's done, the rotor drive collar and the cam gear will slide off.
I won't be surprised if you can then unscrew the remaining part of the bolt by hand. Or you might need pliers.

Ditto on Tom and Van's recommendation...
If it were me, I would drill it out while it's on the car ... It's like putting your cam tower in a vice ... no worries about it moving while your drilling the bolt head out
Also, I bought a very good set of Triple Square (cheese head sockets) http://www.zdmak.com/wbstore/main.as...CTMP=1&LowCt=0
Wow, I just looked up what I paid 9 yrs ago, and the price was only 24 bucks
The dollar is worthless now ....![Frown](https://rennlist.com/forums/images/smilies/frown.gif)
Good luck

Maybe a smaller drill like the hex drive one?
BTW next time, maybe you can do it yourself this setup? It worked for me...

Pretty close to what I had in place. I placed a 2/4 down lengthwise by the frame rail , and the 1 1/4" wrench sitting on top of it, then had the wifey hold the wrench in place as I proceeded to strip the cheesehead bolt.

I think it has to a lot to do with a number of factors...
The tool your using ( that's why I went for the better tool )
The condition of bolt
The pressure you apply on the tool ( I always push in on the bolt, as hard, or even harder on the bolt, as I apply rotational force.
And sometimes no matter what you do, your screwed ( no pun intended) and its gonna strip.
You shouldn't have any problem drilling it out. Just make sure you use a very good bit ... no cheap crap bit ... It's just not worth it ...
If you can't get the clearance,then you need then just take it off and have the wife give you another assist

Hi Phil, There is no better excuse than now to buy some more and better tools. A tinker man always needs extra better sets of the same tools. ![thumbup](https://rennlist.com/forums/graemlins/thumbup.gif)

Going to pull the head tomorrow getting late in the day and i am going to watch Thursday night football. I'll have the whole weekend to pull the intake and replace the old vacuum lines while i'm there, remove the reference sensor, pop in a new one, and try to remove the AOS or should I say PITA and clean p the car a little more by scrubbing with some toothbrushes.
