NISSAN Pictures of how I changed the rear main seal on my 87-95 Nissan Pathfinder.

I have the transmission out and the rear main seal is leaking a little bit. So I will change it.

  1. This is the back of the engine with the transmission out and the plate removed from the back of the engine. The black circle is the rear main seal (RMS). Something is leaky, so I will replace the RMS since I am in here.

  2. The plate is a greasy mess. Also there is a bearing in there. Hmm. Note to self: take notes next time.
    what is that transmission bearing

  3. Here I am pressing something out of a bearing. Probably something to do with the transmission. Possibly.

  4. Anyway. Four little bolts hold on the RMS assembly

  5. Cleaned up we see the RMS holder, the RMS, and a little rubber seal that goes between the RMS assembly and the oil pan. A new one of these came with the RMS.

  6. I wrote down 5 ft lbs on my copy of the FSM - Factory Service Manual. Did I mention a FSM is VITAL to do this? This page is just pics of my vacation. If you wanted to do this, you would need a copy of the FSM. Seriously. Come on. Probably that is how tight I tightened the bolts that hold on the assembly. I put a tiny bit of grease on the RMS to help it slip into place easily.

  7. An I put a tiny bit of Permatex small engine moto seal on the oil pan gasket. Also I said a prayer to Jobu and sacraficed a chicken to the oil leak demons. All to no avail. Leaky still.

  8. There it is reinstalled, and ready to leak again.

  9. Next I sold out to make 02ยข so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.

    But no minivans!

  10. Then I finished my beer.
