Using a razor blade to remove an old head gasket wouldn't that scratch up an aluminum head?
Asked in Head Gaskets and Valve Covers
How do you repair a blown head gasket or cracked head?
A blown gasket can be repaired by replacing the gasket...if you are talking about the head gasket, then you have to remove the cylinder head from the engine block and replace the gasket that is inbetween them. Cracked heads generally have to be replaced because they are made of aluminum which cannot be repaired permanently once it is cracked.
