Smoke Coming From Gearbox Shaft Into Cab

[michaellenehan]

G'day I've got a R32 GTR and have been getting smoke coming up through the rubber boot under my leather one on my gear shifter.

it doesn't smell like oil and am a little worried about where its coming from, has any one had a similar problem?

it only appears when doing anything above 70k/h

I've noticed this with my 25 box, seemed to be after sitting on 100kmh down the highway for a while.. never figured it out.

First time I saw it I thought there was wiring on fire but it didn't smell like burning insulation or even oil, my only guess is it was steam coming from condensation in the box (it is open to atmosphere after all).

Yeah same with my 25 box!! i freaked when i saw it as i was bring the car back to TAS from Brissy! but doesnt smell like anything at all, so I think also, that logically, it would be some kind of condensation

I've had this problem myself when i had my 33 i thought it was a problem with wiring as well lol.

Talked to my mechanic about it and he has seen the same problem before it turns out its the rubber boot around the gear shift, mainly happens in 5th gear as thats the biggest stretch for it.

We ordered a new boot from Nissan for like $20 and it never happened again, and yeh it was like a white smoke but didnt smell like gear oil at all but was def coming from the gearbox.

Cheers.

Yep same with my 32 GTR.... Only notice it on the highway. The gearbox does have two breather pipes (i assume one is the transfer case). I've been thinking about extending the lines into the airbox to just burn it, or back past (ie downwind) of the shifter location to see if that stops it coming inside.

Yeah well my 25 box only has one breather so you're probably assuming correctly

Guess I'll get myself a new boot too.

There's two boots;

1. Gearbox to shifter

2. Body to shifter (over the top of #1)

On mine 1 is broken, and 2 is loose, so i've put a cable tie around the top of 2. Might as well made sure they're both in tact and airtight.
