My fr iend went to go change my oil today and said there was a pretty bad oil leak . I noticed my car was leaking oil as it would always leave spots on the floor. I would like to get it fixed. He said its All along the AC compressor or something. Any ideas on what it could be ?

 

oil sending unit. it's in the how to's or faqs

 

the oil pressure sending unit is a very common cause of oil leaks on 4th gens and is located in that general area. it could be coming from that. it is just above the lower oil pan on the back of the upper oil pan. it's really easy to change i could do it in like 5 minutes.

 

My friend said that it was in front of the oil pan near the radiator side if that helps at all ?

 

i have the same problem. can someone who has time please post the location of the how-to for the oil pan replacement or the oil pressure sending unit?

 

anyone have an idea what else it can be ??

 

the oil press. sender is easy. they make a special socket for it or if you cant find that a deep well 1 1/16" will do the trick

 

but how certain are you thats the problem thats what i mean .

 

Check your valve covers (common leak). Could be running down from the front cover. Oil pressure sending unit is on the back side of the engine. Usually the wires coming out of it will be covered in oil if its leaking. But it can run down to the oil pan and make it look like it's the oil pan thats leaking. Get some brake cleaner and clean it up and check it after the car runs. I know how frustrating oil leaks can be on these cars sometimes it's really hard to tell where it's coming from because it's hard to see. I've had all of the above leaks plus my front timing cover.

 

is it hard to do the valve covers ? If thats the case.

 

Front one is a piece of cake. The back is a PIA because you have to remove the intake plenum (Not too bad though). There is a writeup on it somewhere on it. Don't have a link maybe someone else can help out. Buy the gaskets from Nissan and don't forget the seals for the spark plugs(you have to buy them separetly 3 for each cover)
