RMS Rear Main Seal leak

[XPLORx4]

For the past couple of years the rear mail seal of my Pathy has been leaving small spots (1" diameter) in my garage, and recently the dripping has gotten a little worse. It's finally time to replace it, I'm afraid.

 

What's involved with replacing the RMS? What has to be disconnected/moved/removed to do this? I want to know if any aftermarket stuff I've installed will interfere with a shop doing the work. I don't want them to screw up anything I've put on that's not "OEM".

 

Crossmembers removed? Tranny needs to be drained? I've got some $9/qt Amsoil ATF in the tranny now, so if the fluid will need topping off or replacing, I want to be sure to give the shop the good stuff.

 

If anyone has done this before, your advice would be appreciated!

Hey man.

 

I know the R50's and WD21's are obviously different but as far as I know, the Tranny is the same, and the engine blocks are Almost identical. From what I've read on other posts here from guys doing their's it's easier to remove the tranny. Although if you're thinking you could do all the other work like, Timing Belt, Cam/Crank seals, Water Pump, blah blah blah, then maybe you'd be better off pulling the engine. Regardless, There's a couple threads talking about a RMS job. For the WD21's Nissan charges 8.5 hours to do a RMS job. Once again, I know they aren't the same rigs, but might give you some answers or more questions about what else you could do while doing this job.

 

May want to talk to a few guys that have done them here.

I thought I had an rms leak...

when I did my cams I discovered that the rear cam bolt cover plates on the back of the head were leaking.

the oil runs down the back of the block and dripps right where you would think and RMS would drip from.

they are much easier to remove and re-seal than the RMS so check that out first.

I had to do that and let me tell you it's a $600 job if you get a deal.
