Hi, my wagon has only 47,000 km's and has suffered Front Main Seal and Rear Main seal oil leaks thankfully repaired under warranty, also reverse sensor and now Crank Shaft Sensor oil leak. I know these cars are supposed to be bullet proof but isn't this a bit premature and unusual for all these oil leaks occuring after each other. Has anyone had similar problems? Also what and where is a crank shaft sensor? This car has regularly been serviced and never abused. Thankyou for any insights into this matter.

Hi Sagatarian

Does the car do a lot of short runs...around town, stop start, etc. If it does, there is a possibility that it could have glazed the bores, which allows excessive sump pressure to push oil out the weakest point. In our business we see this happen a bit. Mind you, it could nust be bad luck.

I do short runs here and their but mainly use the vehicle to travel to the coast 200km one way. The rear main seal was found to be damaged or faulty from factory.

Hi there,
You might want to consider this possability too.... "pressure buildup" inside ur engine. Possible cause could be a kinked breather hose. If you look on the back of your rocker cover, there is a round dish like thing that has a hose comming off it and usually they run into your air intake box (depending on what setup u have), if this hose is kinked it will cause pressure to build up inside ur engine. This sounds like a possible cause to me for the simple reason that u stated u have had both front and rear seals leak.
4.2's r bullet proof, very unusual for both to leak. I would be checking that hose for starters.

Cheers Ange

Nissan have diagnosed an O ring that they played with previously was over tightened. I don't know where this is situated. Service people did not know because the mechanic was away. When his back I'll know for sure. Thanks for your response.

Not religious, just a single dad that needs to go shopping and work. Fair bit of the 47 k's travelled on highway to the coast.
