is the 1.6 liter a six cylinder or slant 6 cylinder by any chance. if not. look for fuel pump location, is this where the oil dripping. or cover that has bolts that have a cover there, if so the gaskets for the cover or the fuel pump gasket needs replacing., try crawling down there when the car is running and see if it linking from the oil pan toward the front cover of oil pan. look where the timing chain location it on the front of motor, and the fan maybe blowing the oil over there. or it could be the vavle cover top cover where the lifters are located, the oil can be linking from there and running down the motor, you will idea the bad gasket remove the bolts, clean off oil, old gasket material, new gasket sealant and gasket sets, bolts down, lets setup few hours, refill oil levels, and everything should be okay.

Try replacing the valve cover gasket. If the valve cover gasket still leaks oil after replacement try adding standard 1/4 lock washers to the top of the valve cover bolts. I have a 2005 Suzuki Reno and had to replace the valve cover gasket several times. Adding the washers tightened the seal of the gasket and prevented any leaking,

I have just spent $1500.00 to fix this low oil pressure problem. The main cost was having the timing chain replaced and where the oil pressure problem was found. The low oil pressure problem is caused by a bad gasket that is under a plate inside the timing chain cover. The dealer wanted to replace the whole housing as Nissan dose not offer a new gasket and wants you to replace the inner timing chain housing. The plate covers part of the oil gallery, the gasket breaks out from this plate and that is where the oil pressure goes. The gasket can be replaced by removing the plate and making a new gasket. Note getting to the plate inside the timing cover is a major labor issue that takes about 12 hours to complete start to finish. I had to fabricate the gasket my self as the dealer would not. Cost for fixing the bad gasket was about $17.00 for materials. Replacing the timing chain was at my request as it was making noise.
when u replace the head gaskets u must also replace any parts gasket that u remove (valve covers, intake manifold etc.) to get the heads off, they sell what is called a "Valve Grind" gasket set that is what u need, it will have all the gaskets in it u need..
Pull the alternator brackets and front engine brackets off until you get to the water pump. You will also need to remove the fan shroud and then the fan. Remove the water pump and then you will see an aluminum cover and that will be your timing cover. remove the cover and clean all the gasket off the engine and the cover. use a razor blade, and make sure there in no oil or grease on the parts where the gasket lies. Put your gasket on, bolt the cover back on with the new gasket and repeat the teardown process in reverse.
Before you go out and replace the timing cover gasket; check to see if the timing chain tensioner is not the cause of the leak. I will bet you a FixYa rating that the tensioner is the culprit, not the cover gasket. I replace tensioners every week, and I have never had to do a cover gasket.
Also, the answer given to you by "suterman" is 100% WRONG. Your car has a timing chain, not a belt, that is why you have a tensioner, and it is leaking. And, if he had any clue about cars, he would know that you pull the balancer off BEFORE you pull the cover. In any case, you need to do little more than replace the tensioner.
Use a film of gasket sealant on both sides of the new gasket when you replace it. When installing the cover, make sure there isn't any wiring or anything that could get caught under it.
