Oil Leaking from Top of Engine on Honda Prelude

The camshaft seal, located at the end of the cylinder head, has a reputation for failure on the 1992-1997 Honda Prelude.

This seal wraps around the camshaft to prevent engine oil from leaking where the camshaft exits the cylinder head.

Replacing the leaky seal requires timing belt removal, so timing belt and water pump may be recommended if your vehicle is near the service interval.
