Suddenly there is a noticeable engine oil leak coming from the front passenger side of the engine. Oil level has fallen below the hash marks on the dip stick. Refilled about a quart today and later noticed a six-inch long spot while idling.

No other issues. Plan to lift it up Monday morning after a weekend of little, if any, driving.

All suggestions welcome. When the dip stick is below the hash at the minimum level, how much oil is gone?

Would front main seal be a good guess? Oil pan gasket? Puzzled as to why it's on the passenger side of the engine. And so quick to develop.

 

Len I see you made it into the right section (XJ XJ8 X308):

Our AJ16 and V12 oil leaks come from the left side of the engine, not the right! Really! But THIS is where the Carnival Red cars began. You're welcome.
