I had a 1982 Nissan Sentra That had a bad head gasket at about 130,000 miles. Yes you can do it, but you are just putting off the inevitable. That particular year model is widely known to begin with head gasket problems and it just gets worse. I would advise you to unload it as soon as you can because you don't need what's coming down the road. I'm a Nissan fan so don't everybody start saying I'm anti-Nissan. I you owned this particular year model for any length of time, YOU ALREADY KNOW WHAT I'M TALKING ABOUT!!
It can costs anywhere from 10 to 20 dollars to replace an oil pan gasket on a 20045 Nissan Sentra as of 2014. The exact price depends on the seller.
the only true way repair the leaking oil pan it to remove the pan and change the gasket their is no quick fix for a leaking oil pan if you do it right the first time it wont bie you in the but latter
Leak or blown gasket.
have a mechanic sheck for a blown head gasket or a craked head
either sell the car or pulley engine out
look at your engine oil you may have a leaking head gasket
leaking valve cover gasket.
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
More than likely you have a valve cover leak. You probably need to replace the gasket(s).
Specifically where is it leaking? At the gasket? Replace gasket.
replace leaking part and or the gasket where the leak is occuring. check all hoses to make shure its not leaking from the hose
