I'd also have to say the front and rear lower intake manifold gaskets are suspect. The replacements I've seen are of the 4 piece variety, and they can be a PITA to get right.

If you were leaking from the PVC, the oil pressure sending unit, or the valve covers, you'd probably have smoke burning off the exhaust.

The oil pan gasket is on the front and the back of the engine, obviously, but the oil should never travel upwards. If it's getting thrown around by the belt, or something like that, you can eliminate the oil pan.

The timing case cover won't affect the back of the oil pan, but it will let oil get thrown all over the place in the engine compartment. Look for oil under the hood, spray pattern should line up with the belt.

The head gasket can also technically cause it, but I can't believe it would be leaking at the back and the front.

Are you sure you are losing oil? Could it be power steering fluid? That can throw the fluid all over the front as well.

Finally, the front and rear main seals can leak again after replacement due to the groove they wear into the crankshaft and the front can cause oil to spray around sometimes. They are far more apt to show leakage after the engine is off though.

Later,
