I see we have the same argument going again for this copper coat crap!
If a head or block is damaged some way,copper coat is Not going to fix it.If its cracked copper coat wont fix it.If its warped,copper coat wont fix it.Copper coat is used to hold a gasket in place while you fit another piece up.It also doesnt stick so bad that you cant still move it a little to get the bolts in.
I dont know whos idea it was to put the copper in it,but a few rare times I have used it on something that was boogered up and it sealed it.Silicone works way better in my opinion.Once they came out with high heat silicone I quit using copper coat.I still have some,but I only very rarely use it.
If you wanted to seal up something that was boogered up,and you didnt have any money or something,you might get you a tube of high heat silicone and put it on the boogered up place real thin and get by for a while.Copper coat is not going to work for that probably.

Lots of the stuff I ever saw with a Blown headgasket had a loose or head popped off of a headbolt.A few times I saw some engines that had been rebuilt numerous times and the headbolts were wore out..You might want to see if the head bolts bottom out before they get tight.But It is real doubt full that you would ever fix a head gasket leaking with copper coat.You will stand just as good of a chance that it will leak because of using it.So copper coat wont fix you stretched out head bolt,which is something I forgot about until I wrote this.It wont fix your loose headbolt or broken head bolt.It wont fix pulled threads,or bolts torqued wrong.
Of all the stuff I ever had to do over again,I had very few head gaskets,and a few engines that I worked on ran far enough to where I rebuilt them again.
The place I worked at was a good shop where you could take stuff everybody else tried to fix,and get it fixed right.They sent us to schools and the boss was out there working with us in the shop.
If you think about it,it makes sense.If you bolt something together without any sealer on it,then its more likely not to move.If you put a bunch of silicon on a valve cover gasket and overtighten it,the gasket will shoot right out.
There is no telling what I would try to fix something.I even put silicone on a head gasket one time and it didnt work.Im saying leave the copper coat off of the head gasket,especially on a diesel.

Now maybe,under the right circumstances,with an old gasket,you might want to put shellac on it.If everything is clean and straight and you have a new style gasket,you should not use any sealer.
