Replaced timing chain and water pump (I did the work) approximately 1 year ago. Three months ago oil is leaking from the bottom of the timing cover. Could it be anything other than a crankshaft main seal? Hope so. My mind is still on cars 50 years ago when they had front and rear main seals. Ho pe it's minor. Car has approximately 90k miles and runs like a top. All advice appreciated.
