I have copper head gaskets and the block is o-ringed(on the block side no recess). I do not know when it started,but it has been a least a few months that I have developed a leak under high boost or N2O at times. It does not happen all the time but when I beat it on the sreet or track my overflow res. will bubble and almost fill up. I assume this is combustion blow-by? somewhere?
Anyway it has not been a problem so far and I have no coolant leaks. What should I do, I would perfer to wait until winter to do any thing.
Re-torque?
change headgastets?
get rid of the copper?
Thanks
