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.Google+

Oil leaks that are substantial coming from inside the timing belt cover are usually from the oil pump seal. The front crank seal won't leak big time, as there is not that much internal pressure, unless your PVC is totally plugged.

I had the leaks repaired, but still have a small leak.
