Default Copper coat on head gasket?

     

Okay so my head gasket leaked since i replaced and rebuilt my top end. I ordered stock nuts because i had to use different ones so hopefully that is the fix but some people recommended using "copper coat" on the gasket but I've never seen anyone do that, i also wondered about the coolant going through the gasket if the copper coat will get in there and clog it up. I just don't want the new gasket to leak.
Thanks,
Isaac

I have used it on car engines. I have heard of some old timers using silver spray paint on their head gaskets.

The copper is a great thing to use its a soft metal and therefor will squeeze and seal really well. All my gaskets have it on them.

The head gasket is also copper, so i wasnt sure. we're going to see if the new nuts fix it and if not we might try copper coat.

If you are going to pull the old nuts off then you should probably go ahead and replace the gasket entirely before throwing the new nuts on. As the others have said, nothing wrong with a little copper spray on your new gaskets.


Edit: Just reread your post and looks like I over looked the fact that you are going to replace head gasket and not reuse it.

Yep, just replaced it and used copper coat, seems to have sealed much better but we'll see when we start it up and ride it for its first break in rides.
Thanks,

Just putting it out there... Are the gasket mating surfaces flat?

Sometimes you can warm the copper gaskets first then fit(??)
