Need help on Timing Belt Replacement (for Pathfinder 97)

I tried to replace timing belt for my pathfinder 97 (XE V6 3.3L 4wd) last Sunday.

I had successfully removed radiator, fan clutch, radiator hoses, all drive belts. But
I can not figure out where is the breather hose and breather pipe, which according to
the Haynes manual, need to be removed before i can remove the timing belt cover.
But it didn't tell me the detail.

So I kind of chickened out and replaced all drive belts and installed everything back because
I need this car next day.

Can somebody give me a hint on what are is breather hose, what is breather pipe, what
do these pipe/hose do? How to remove it?



Thanks a lot

That's the pipe in front and on top of timing belt cover, connecting from one valve cover to other.

Can you remove a crankshaft pulley bolt?. Try to remove/loose it first before going in too deep.

Thanks a lot for your help!

Could you please tell me what does breather pipe/hose do? My guess is to expel exhaust out?

Also, I have taken some pictures by using my digital camera after I removed all the drivebelts,
could you please point on the picture where is that breather hose/pipe. Can someone tell me how
to post a picture in this forum?

On your very last pic (img_0578.jpg) .

There's a hose in front of the distributor that connected from air duct(air cleaner housing) to the pipe(breather pipe), the breather pipe/hose also runs from one valve cover to other, you will need to remove that pipe/hose first prior to remove the timing cover.

Again, I'd try to remove/loose the crank pulley bolt first before going too far, if you have a good 1/2" air impact wrench and air compressor, disregard this, otherwise you may stuck in the middle of the job.

Like new guy said try to remove/loose the crank pulley bolt first before going too far,Sometimes a rachet with pipe over the end will make help to take off nut.

Thanks guys!

Advanced Auto Parts have a tool for rent called "harmonic puller" for 89 bucks. If I
return it within 45 days, they will give full money refund.

They claim this tool is perfect for almost all kinds of crankshaft pulley. But I don't know
if it will help to remove the nut. I will check with those guys tomorrow.

Seems you all recommend to remove the crankshaft nut first. But according to the manual,
I need to remove spark plug and set TDC before removing crankshaft nut.

How do you think?

Besides, could you please kindly tell me:
1. what is breather pipe/hose, what do they do?
2. On the picture I posted, please pin point where they are.
Or should I retake picture because the current one does not have a whole set?

Thanks
