Your Altima uses a variety of different oils to lubricate various components. Normally, these oils won't leak. But when you do find a leak, you will almost always need to have extensive work done on your Altima to correct the problem. However, before you can replace anything, you need to know what kind of oil it is Check for brown or black oil leaking on the ground or on the side of the engine. This is engine oil. It lubricates critical engine components. A leak means that an engine seal has failed and needs to be replaced
Check for red oil. Red oil is trans fluid. On your Altima, it most likely means that you have a rear main seal on the transmission that has failed. However, any seal on the transmission is possible. Transmission leaks need to be fixed immediately. A transmission can fail catastrophically in 20 minutes of driving if there is insufficient oil in the transmission
Check for amber or brown oil leaking from your trans. This is transmission gear oil found only on the manual version of the Nissan Altima.
Yes, a bad head gasket can cause a leak between the engine and the firewall. The head gasket is a critical component that seals the space between the engine block and the cylinder head. If the head gasket fails, it can allow coolant, oil, or other fluids to leak out of the engine and into the surrounding area. In some cases, this can result in a leak between the engine and the firewall. It is important to have a faulty head gasket repaired promptly to avoid further damage to the engine.
Juan, Oil could be leaking from a lot of different location, places to start looking are oil pressure switch, valve cover gasket, timing cover/crank seal, oil pan gasket, etc. Engine may have to be washed down to locate leak. Have a good tech. scan vehicle for trouble codes, diagnose why car dose not run and estimate repair. Check the attached links,instruction and guides, Good luck

manual transmissions don't normally use flowing fluids for lubrication they use gear lubrication oil/grease these are heavy hi viscosity (maple syrup like) and don't flow like water like automatic trans do , ck'ing there level is a bit specific to what type of lube they use , a Hyundai uses Oil so there will be a pipe plug up on drivers side of trans near top (sorry no dipstick) un screwing this will allow one to use a Non metal object to stick in and see if oil is up to hole (reaching it) , of course obvious(wet look) signs of leakage (at drive shaft and clutch cover ) are a sure sign you have a leak and level is low , wet clutch covers aren't allways a sign of a leaking transmission but to one of a leaking clutch slave cylinder(common problem on Hyundai's) this is the device that moves clutch inside , ck oil level in clutch master cylinder to confirm this
Hello! Sounds like a ride to me...Since you do not see any oil on the pavement, and it's using oil at an excessive rate, I would believe you would see blue or black smoke coming out of the tail pipe... let me know if you do...Also, does the engine run normally?...No hesitation,or rough idle?...A plugged Positive Crankcase Ventilation (PCV) valve will cause an engine to consume oil...See photos below... First is for a 2.5L and second a 3.5L...Both cost around $10...Guru.....saailer
You have to identify where the oil is leaking. Check the spark plugs if it has oil, you may just need to replace the oil seal in the plugs. If you meant actual burning from the exhaust, you may want to check the head gasket and the piston rings if the oil seeps into the combustion chamber.
