Hello I have a question, my 350z 04 has been releasing a lot of smoke from the exhaust and was wondering if anyone know what causes this.

 

Spy Hunter smoke screen

 

I have the Bond James Bond model with optional oil slick release and anti-bullet screen pop up.

Butt seriously...

Trying to even "armchair diagnose" without details is next to useless.

- Color of smoke?
- How much and when? Idling, driving? All speeds?
- Engine hot/cold?
- Ambient temp?
- Mileage on car?
- Smell?
- Any recent work done?

 

Seriously, though. Where do you mount the machine guns?

Smoke in exhaust... I think it's due to combustion unless OP got one of those EV Z's.

 

depends on the neighborhood, might be right hand.....might be left

 

The color of the smoke is grey, when I turn it on of course smoke come out but a slight rev release a lot of grey smoke. Can not really notice allot of smoke coming out when driving. always warm up engine no matter where I take it. It has 140k miles on the car ,smell like gas and no recent work has been done on is as I just bought it.

 

Most likely a blown head gasket, coolant is seeping into your cylinders when the car sits for a while and then gets burned out during warmup period. This is why it's really noticeable at cold startup but not so obvious when cruising. Get a head gasket chemical test kit, follow the instructions on the packaging, this will give you a quick YES or NO answer to if your engine needs new head gaskets.

If the test shows positive (YES, blown), then you have a tough decision to make.
1) Pay a shop to replace gaskets (huge job, very costly).
2) Replace entire engine and gamble on a used longblock (cheaper in terms of labor).
3) Ditch the car and take the financial hit (hope you didn't pay much for it).

Good Luck!

I will do a head gasket test and I think that might be the problem . Also ima do the challenge to replace it myself. I will let you know how it goes.
