Copper Spray on headgasket?

By teal_dx
- Tue Apr 01, 2008 2:54 pm #48634 I replaced the head gasket because I suspect there was a very tiny leak. Temp gauge was rising sometimes and there was an oily film on the surface of the coolant when I drained it.
The Head gasket was in good shape, not sure what could have caused this. I did find a tiny gouge on the surface, on the top of the #3 sleeve, on the edge right beside the #2 sleeve. I don't know if this had anything to do with the possible leak or not. But that was while breaking in the engine NA, I'm putting the turbo on next so I want some extra insurance that it won't happen again.
Do you recommend using copper spray?

You risk copper spray and have a chance of removing the head again or do it right and be a little less worried about it leaking due to uneven surface on the head.
