Rear main seal helpmes

I have a 1999.5 Nissan Pathfinder that has a rear main seal leak. It is 4x4 and it will cost me a fortune to have someone fix it. I have heard that there are products that i can add to my oil that will stop the leak, or at least slow it down. I have tried Barrs stop leak and that did NOTHING for it. Is there anything else out there that I can buy to help this problem? I cannot afford a $1600 bill to fix my truck, and probably never will. I am also tired of spending 10-15 a week on oil. First its a paiin to have to go to the auto parts store 3-4 times a week plus i know it is a complete waste of time. Please please help!!!

If its that bad your only option is to pull the tranny and replace the seal also check the condition of the end of the crankshaft where the seal rides for excessive gouging or the new seal my not seal without first repairing or replacing the crank, this is rare however and a new seal should do the trick. i recomend shopping around as the seal only costs about $25 and the major cost is removing the engine or transmission to replace it (wich ever is easier sometimes the motor is, but anyway maybe you can find a local friend or family member who could R&R the transmission or motor for you at a good price id say around 500-800 would be more than fair, look around you would be suprised when a shop is slow what kind of deals they will give out just to get some work , good luck please rate Ps those additive are not going to work as the seal has failed very badly and has nothing to hold back any thickness oil, the additives are only hurting your motor -jeff

Nothing will really fix it other than new parts.  It's not bad job, just time consuming.  Need a way to hold tranny up while pulling parts.  Have a chilton or haynes manual.
Basically though, you need to remove transmission or be able to move it back far enough... remove flywheel from crankshaft end... unbolt and remove rear main seal retainer... replace seal and gasket... reverse procedure.

1999 ford expedition - rear main seal leaking


I don't know why your mechanic needs a picture of the seal. Here is what you will need to do. The tranny will need to be removed because your vehicle has a one piece real seal. After you remove the tranny remove the flywheel then you have access to the rear main seal. If you have never removed a tranny leave it to someone capable of the job. You will need many tools to remove the tranny and a little muscle here and there. It is an easy process for a mechanic, but labor intensive.
