Anyone know what this hose is for? It dies not seal on its connection due to being burnt. Can this cause any problems? It goes under the intake manifold passenger side. Can not figure out how to load pictures so I hope link works

That is part of the crankcase ventilation system. It connects the 2 valve cover chambers so that the one PCV valve can do both sides of the engine. I had to replace my hose when I did valve cover gaskets because my hose was so brittle that it cracked when I took it off.

 

THAT

I advise you get a new hose ASAP

 

Can't tell from the pics but it looks to be your pcv hose or one of the crankcase ventilation hoses, so yes it will cause problems if its not sealing properly.

 

If I'm not mistaken, it's a vacuum hose that bridges from the front valve cover to the rear valve cover.

If it's cracked or if it's not holding a seal I'd get a hose and replace it. I replaced mine with a generic aftermarket hose.

 

Oh you guys replied while I was sitting here typing then watching tv and by the time I hit the reply button you had your answer already OP.

 

Thanks for the reply. Dealer only hose I am guessing?

 

as stated above, it can be had aftermarket too.

 

as did I, take your old hose to autozone or something match it up to a generic hose

 

Me three.

 

Generic hose works well. Make sure the diameter is the same (Take your old hose when you go to AZ or O'reilly, etc). Get it fixed as soon as possible.

 

Yeah I was talking about the actual direct fit hose.

 

$2 hose from parts store > $40 hose from nissan

 

Ok aftermarket sounds good to me then. wow what a price differance

 

What happens if not replaced??

 

You can get moister/water or other contaminants in the valve cover. That is not a good thing.

 

Thanks man, i gotta replace mine asap then

 

Hah! I've otta buy a bigger hose since I'm going 01VI

 

that's what she said oh!!

 

I wish I was going VI... sigh.. one day, when I pay off all this debt.

 

When I did my gaskets I replaced all my hoses. I guess you must like the stealership to even mention them lol

 

Maybe he is the stealership

 

Yeah I broke down and went to the local dealership. It was $13.97 so I ordered it. If it was $40 as stated above I would have passed.
