replace the front oil seal. first i would clean the engine with purple power (degrease etc.) then look at the engine and make sure the leak is not coming from above like possibly the valve cover gasket or from the oil sending unit. try to tighten the bolts on the valve cover and even the oil pan. you never know, you may get lucky. i don't know where you are but front seals are cheap but the labor on the job is what costs you.

Well, from the oil pump it goes into your oil filter so the lines going from the pump into the filter could be clogged. check that and see. Also on most imports I have found that they have to be primed after the oil pump has been replaced. Buy a oil pressure gauge and hook it up. Disconnect your fuel and spark delivery and then just crank over your motor to make sure you have good pressure. It takes up to 30 seconds to build on some cars. hope that helps.

You should use the viscosity oil recommended in your owner's manual. Using a heavier weight oil can affect your fuel economy. If you overfilled the engine with oil, drain out a quart. Overfilling with oil will cause the oil to 'foam', and if this happens, you are not getting proper lubrication of components, which can result in damage to your engine.

a lot of people have reported this issue with the 2001 Nissan altima. it is a design flaw and the idle rpm fluctuation is caused by a bad intake manifold gasket. the part only costs about 10 dollars but do to the 5-10 hours it takes to replace it is a very costly on the labor side

if your car has alot,saying that im talkin 200.000 plus miles on it poss could be that sensor o ring,they very rarley fail unless lots of miles on drive train.without knowing how bad the leak is or any other pertinant info, like any recent service done? how long has it been leaking? does it only leak while running?while running under a load? or just sitting? all off the above? my guess would be valvecover gasket,front cam seal,oil fill cap, cyl head gasket? with just the info at hand to go on it could be any of these things pretty much in that order,if you can do a little more investigative work to answere some of the questions i asked you should get a verry accurate answere and poss things to address along with whatever maintenence needed to remedy the leak .
