just after some info on my gearbox breather for my sierra???is it ment to pop up and down/spring loaded like my transfer and diffs?i noticed it was stuck shut and that the little holes at the top sides of it were blocked so i used a pin to unblock these.
Could this possibly be the reasoning for my gearbox leak,maybe pressurising when hot?
if someone could tell me if its right or if i need to lever it off or something thatd be great thankyou,matt

pop the top of both that one and the transfer and put some fuel line on both ten run it into a T piece them up to the engine bay or into the quter pannel away from water do the same with the diffs

thanks jimbo thats what made me start looking at all this in the first place,wanna go longer breathers.
so you are saying that outer piece ontop of the zook box comes off,its different to the one on my transfer,its just like a outer sleeve

Running garden hose is a good idea for breathers, a lot of people do it.
If you are talking about gearbox oil leaking out on inclines, all sierras do it, it leaks out the gearshift lever hole, you cant really stop it.

The slit in the bell housing?
If that is the case I'd pull the gearbox off and inspect, could be the engine rear main seal.

yeah agreed,mine was just about on its side one arvo,and when we were disussing a recovery plan,we saw oil running from the box,down the tunnel,over the case and i thought id cracked the case too,haha but then later saw where it was from

If it is indeed coming out that little slit, then you have either a rear main seal or an input seal kaput, which is not a good thing, as if you get oil on youre clutch then you could lose drive at a most inconvenient time.

maybe that will be a good thing,then ill leave it out bush and forget about it.haha na i know i really need to pull it out and check i just cant be bothered,i just wanna drive the thing.i sometimes think rear main,by look of oil etc,then other times i think its gear oil by smell or whatever,only real way is to sack up and get her apart
maybe after tomorrows wheeling
