New clutch = new rear main seal?
I hope this q doesn't sound completely newb-ile....i have done clutches before but only in various 4wds....since my Z is so low to the ground, I hired a mobile mechanic to do most of the work for me.
I read the write-up on this page and saw no mention of a rear main. Of course I read it on my iPhone so it's possible I missed it....
Can anyone say for sure that this is necessary and or recommended ?? Thanks!

Well it hasn't shown any sign of leaking and there's been vehicles in the past that leaked afterward so I'm kinda of the attitude that 'if it ain't broke don't fix it'.
Is there a recommended replacement schedule on these? I'm only at 55k miles

If you are already there... the extra 5 minutes and very little cost it takes to change is well worth the total cost vs basically changing the clutch again if it starts leaking later.

I'm doing my trans job this next week so I decided to look at what it would take to replace the rear main seal. First of all - no dealerships in the country have it in stock. There aren't even that many in the PDC's.. which leads me to believe that it doesn't get replaced that frequently.
Then I saw the location of it... it's definitely not as easy to replace as most other Nissan's.

The '07 service manual says nothing about removing the oil pans to replace the rear main seal. It appears to be accessible after the flywheel is removed. The SM illustration shows the lower cylinder block in place. No special tool is needed to remove it, but there is a tool for putting the new one in.
Is the DE engine different?
Still don't see a need for messing with it if it's working OK, though.

In for VQ35HR info, I would like the rear main seal replaced soon as I am doing clutch to !

its not really necessary unless its leaking. 2 clutch changes and havent ever replaced it and its runnin like a champ.
best thing would be to visually inspect it and replace if your gut tells you to. im sure theres a writeup somewhere

Oil pan must be removed. It is hard to get a decent seal if the upper oil pan is installed. I would not change it out without removing the lower pan based on having done it with the engine out a few times.

Anyone else wishing to post comments that relate to OTHER CARS please just hit back on your browser and go to another forum before posting false information to users. After you have actually rebuilt a few VQ engines then you can post about how easy or effective it is to fix things.

This is true but if the engine has high miles then there is a possibility that the seal will go bad. I honestly wouldn't replace a normal seal unless I was completely removing the engine (since it requires the engine to be pulled). I would not do it when changing a clutch since it really can't be safely changed with the engine in.

Had some questions about replacing my rear main.
1) Is the seal is driven in from the inner or outer side of the retainer? (pictures seem to show from the outside)
2) Can I do it without removing the retainer from the block?
3) I am starting to leak how long till this becomes a serious issue?

It is leaking and I believe I can pull the seal with the plate installed and press/tap the new seal into place.
White lithium grease on the inner portion and anti-sieze on the outer. done this on other vehicles but not on a Z.
Has anybody tried this method?
