As with any engine, there are multiple possibilities.
Many of the "L" series had the V6 engine, the comments below are for that engine so you'll need to clarify if yours has the 4 cylinder engine.
Valve cover gaskets are a good place to start if you're certain that it's the engine. Also check the crankshaft and camshaft seals.
If it looks like it might be coming from the FRONT of the engine (that's the end with the serpentine belt), make certain that you have it repaired before the timing belt is destroyed.
Also, check the pan gasket. The pans are alloy and don't typically leak, but anything is possible.
Check the oil drain plug and oil filter. If the filter was put in wrong or the drain plug 'O' ring has failed, you'll leak there.
If you're NOT certain that it's the engine, check the Power Steering pump and the rest of the power steering hydraulics.
