I have 1992 Sentra XE and it has a oil leak. I'll top off the oil..and after about 4 or 5 days of driving it's on Low again... I can see oil dripping from underneath the engine in a few different spots. I've heard of parking on a large piece of cardboard to see where the oil is dripping down from, but I'm rather sure it's leaking higher up. I can see oil all over the engine underneath where the air intake connects to the engine. So I'm assuming maybe it's a bad gasket or something of the sort, but is there any better way to pinpoint where the oil is leaking from? I ask because oil drips from multiple spots underneath, all the way from behind the front passenger tire, over to underneath the air intake area (I don't know much about cars, so I hope you guys understand where the oil is dripping from. If I can manage to get my camera under there and take some pictures I'll post them. )

Thanks in advance

My oil leak experience with a b-13 and b-14 with the 1.6 liter is the same with both. Check your front crankshaft seal. It is not hard to change, but is a pain to get the belts off and back on. Easiest way to get to it is by removing the passenger's tire and you are looking right at the pulley. Good luck.

Good thought and Quite possibly an issue.. But if its oily up top there are several options.

Valve Cover................. The highest spot to leak oil
Distributor Shaft seal..... Slightly below VC on driver side
Oil Pressure Sending Unit...Under Intake?? on backside of engine
Oil Filter........ Either the gasket could have blown out or a pinhole from a rock
Rear Main seal ..............Basically between Engine and Trans

Your best bet for finding it will start with a THOROUGH cleaning of the engine bay. Get some GUNK or something similar and follow the directions..(You may want a can or 2 or Brake Cleaner for the harder stuff). DO NOT use a pressure washer of Car wash.. A garden hose will do nicely if you have patience and let the cleaner work.. After the engine is clean...(Bottom too).. Then you can use the cardboard trick... ALso while the engine is running ontop of the cardboard keep an eye on things in the engine. (A small, powerful flashlight can be useful). More than likely you will be able to get a better idea of where its coming from..

Then we can help you fix it..

Thanks very Much Guys,

Sorry I took so long to respond to this but my car just broke down...again...

I've replaced the Fuel Pump, the Fuel Pump Relay, The filter is still good, But it won't stay running anymore. It sounds like it's getting a little bit of gas, just enough for it to run for a minute, on the verge of stalling. Pumping the gas pedal has no effect, other than sometimes when you push the gas pedal it sounds like it's closer to stalling.

And once I can get it over to my Grandfathers house (need to find a friend with a trailer to use), I plan of cleaning out the engine bay, it's pretty nasty under there. When I get this done I'll update again.

Once again, Thank you guys.
