    NO QUICK FIXES HERE. CARRY EXTRA OIL TILL YOU HAVE TIME TO REPLACE THE GASKETS AND SEALS. MIKE

      Yup! That's the way it is. Also, when you do get around to replacing the seals, I suggest that you use silicone RTV in place of the rubber end seals. If you apply it carefully and properly it will do a far better job of sealing than the stock-type seals. GM went to this method in the later C3 era for all small blocks.

      I recommend using Permatex Ultra Copper for this application. Make sure that the manifold and block end surfaces are COMPLETELY free from any oil before you apply the sealer. Clean them with Brake Clean solvent before you apply the sealer.
