i seem to have an oil leak from my head gasket. good indy found it. he said that it was only a nusiance leak, didn't seem to be under pressure and was no real danger to the engine. i don't even have to add oil between changes, it is very small, but, i so hate the oil smell and will have to fix it or sell it.
so..1 anybody know if this is fixable without a head being pulled?
2 is this common?
3 should i do both heads, or just the current leaker?
4 average price of head gasket job
5 does the block have to be redrilled and inserted since it is aluminum?

thanks guys
