- 3 years later update: Guys, it's either not leaking or not leaking enough to drip on the driveway
This rear main seal installation method is not the proper way to install the seal. Factory service manual for 3.5l Pathfinder states the lower oil pan has to be unbolted in addition to the transmission. The intent of the video is to help those who have either assumed its not difficult to install without dropping the pan, or those of us who did not read all instructions from factory service manual before removing old seal. Hopefully this can save your bacon if dropping the pan is not an option for you.
Basically, sand down less than 1mm of rubber material from the under side of the gasket. sand down enough to eliminate the radiused edge of the molded rubber on the underside until you now have a defined corner. on the back side of the gasket, sand in a chamfer or taper for the corner bits. When installing, use a metal punch (ideally with dulled edges in order to not cut rubber) to assist with pushing and squeezing in the new gasket. If gasket does not fit after multiple attempts, consider removing a tiny bit more material from gasket. Use extra rtv around corners.
Main project was to replace a bad transmission while using PTO at work. Before installing the new transmission I thought I'd go ahead and replace the slightly leaky rear main seal since the Haynes manual never mentioned dropping the upper oil pan. After breaking the first replacement seal with brute force, I came up with this hack job to get another replacement installed. The outcome was that I was able to reinstall my transmission and drive my rig back to work on my next scheduled day. There is a slight oil leak like before, however it's very slight.

This method will work better if you cake on RTV where the seal sits and take your finger run it smooth you'll have zero leaks. I did this with my 05 g35 it's been about 2 months now not a single drop on the cardboard I leave under the car. 😁👍🏽
sir do you know if this rear main seal is one size for all VQ series engine? mine is a vq20de..the one i've seen online says it fits 20de 30de 35de
@@erlindapatio6331 yes it is one size fits all for vq20de vq30 and vq35. 🤘🏽😁👍🏽
thank you so much sir🙏
You mean leave the rubber seal out, install the plate, then pump the gap with RTV and smooth it out? Or put a bead of RTV on the plate where the seal sits, then install the plate?
I just did this .took me 4 hrs .Took a break and went at it again .I bought some of those long needle picks .i put the top screw part on first used the picks to run it inside the circular gasket .I found every time i stuck the bottom gasket in it would pop the top out .so once the top part was in i screwed the screws half way in so it wouldnt pop out anymore.Then since the lower half was still out i made sure the bottom gasket tips where in first and started stuffing it in whit a flat new screw driver slowly ,tapping it in and runing the pick around the inner small gasket like you would do a bike tire. Fit really snug.i also added extreme rtv before i completely pushed it in .
Are you located near nyc?

I wouldn't file or sand down ANY seals. I would follow the manufacturers suggested advice for removal & installation.
As for selling it and letting it become someone else's problem.....
that sucks.👎
ITS GONNA LEAK FOR SURE...
Lot of work for it to leak still
the upper and lower oil pan need to be removed to install this seal. i have seen it done without removing but that method is only about 75% effective.
Why would u do 85% of the work and do it half ass. Or even take a chance of it still leaking.
Do you got to remove the trans I’m trying to figure out if I can do this in my driveway
@@benddover3093 lol, yeah you can leave the transmission in.
@@tomr1107 really you can leave the transmission intact?
@@benddover3093 no. I was being sarcastic. Everything needs to come out. The trans and clutch and to do it right the upper oil pan. It’s a lot of work.
How well did this method seal? I myself am in the same situation pulled everything then said damn 😂
It leaks ever so slightly. It’s a bit better than the old 127k mile seal though
@@dospathsgarage2854 is still has a rear main seal leak ?
@@davidreedy4882 slight leak
No
bruh
Well, that's not gonna seal right lol
😂 why would anyone watch a video to do a hack job? 😂 When they can butcher it themselves.
