Automobile PCV valves can leak oil.
Not sure where it is on that model;it will be attached to a hose assembly to let air from the crankcase (bottom of the engine) get sucked back into the intake (top of the engine).
AnswerThe pcv value is located on the value cover next to the oil cap. The pcv value has a hose attached to it that goes from the pcv value to the bottom of the fuel injector. Once you remove this hose, the value can be easily removed with a 3/4" or 20mm wrench.depends on where the oil leak is at
More than likely you have a valve cover leak. You probably need to replace the gasket(s).
Oil leak or engine is burning oil due to worn parts.
The oil capacity of a Nissan Sentra 1.6L is 5 quarts. This includes the oil within the oil pan and the oil filter.
it could be an oil leak.. my boyfriend had that happen to his s10 and he had oil leaking into his exhaust system
twice in 2 years I had to replace the valve cover gasket on my 2001 sentra. Oil would pool around in this area. Last done in December 08 and no problems yet
The 2004 Nissan Sentra 1.8L take 5w - 30
A transmission oil change for a 2007 Nissan Sentra 2.0 costs about $700.
the valve cover gasket is bad, or the valve cover is loose
the signs of a valve cover leak are oil on the engine oil is the only thing that can leak from a leaky valve cover
The location is engine specific. Which model Sentra do you have and which engine does it have?
A Nissan Sentra with the 2.5l engine holds 4.5 quarts of oil. When changing oil, keep checking the dipstick to keep from over filling.
