Smoke Infiniti J30

[Hansdan]

First of all...sorry guys...my English is not so good...I just moved to US 2 years ago. Ok...

I'll be quick.

1. Sometimes, not all the time, when I use the ventilation system, not the AC, and I wait at the light or use a little bit more the brakes...there is smoke/steam coming out from under my hood...driver's side. It smells like chemicals, I can't tell what can be...maybe coolant agent. I checked all the levels and everything is normal. I've been having this for 4-5 months. I'll put a couple of pictures with a certain hose that is wet-dirty...

2. Another problem is...sometimes I feel like a step when I press the brake pedal...especially after I just turn the wheels...

How can I post some pictures in here?

Thank you.

In order to post pics, the best way is to create a photobucket account and to link to this post.

you're hoses are old, you need new ones immediately.

For the brakes, check your brake fluid

The brake level is ok...as you can see in the first picture...I have to change some hoses though...

Looks like maybe a valve cover is leaking.Do you have a small oil puddle wherever you park ?

[Hansdan]

No...and all the levels are normal.Maybe, like naladude911 said, I have to change some hoses...I'll start with the one in the pictures...can anyone tell me what is that hose good for? You have the ends of the hose in pictures 1 & 3. The rear end is somewhere in back of the engine (with that cover improvisation).
