I'm just finishing restoring the engine compartment to stock on my '58 with the usual 235. Before I put everything back together i noticed that my timing chain cover has a slight leak (the engine is untouched and very low milage). I'm going to change the gasket and would like to know if there are any tricks to this change out before I start. I'm relatively new to working on Stovebolts. I want to do it right, can't stand any oil leaks no matter how small. Thanks for the help fellow bolters!!
