Something stronger than Quicksteel resin epoxy

[crazy.vr]

Anyone used Quicksteel before? I used it on the front of my timing cover to fix a water leak and it worked a treat but now I snapped a bolt off more than half way in the timing cover and I can't screw another one in. I have tried putting a stud in and holding it with quicksteel but the stud pulls out when tightening.
Any ideas on an adhesive that is very strong and could withstand the heat of a motor say 150-200 degrees? Thanks.

i would say your best bet is to use Easy-Outs. you'll need to drill a hole in it trying to keep it centred. screw in the easy-out and your done

other method if there is enough bolt out to grip with pliers, remove the timing cover first, might give you enough.
