Front engine oil leaks can develop from the camshaft seal and the crankshaft front seal. If one or more seals require replacement, it may be wise to consider replacing the timing belt as well. These seals are commonly inspected and replaced as needed as part of a timing belt service.

I had a 1998 that started leaking oil onto exhaust pipes at 140,000 miles. At 150K it was crunched while parked, so I bought a 1999 model, which also started leaking oil onto exhaust pipes at about 150,000 miles.
Was told I have cam shaft seal leak by Subaru dealer or main seal leak - cost $750 including timing belt.
Burning oil smell at times. Needed a timing belt anyway so belt and seals were replaced. Unfortunately the head gaskets are now leaking 216,000.
Mine has leaked since day one and the dealer said it was my fault because I change my own oil.
