So...

05 Z Perf 6-speed. 70k miles

I have noticed when I make a U-turn (left), if I get a little bit spirited when turning or turn at a little bit high speed, I notice some smoke coming out from the vents of the A/c and or from the passenger side of the hood area. Its light smoke, and goes away in about 5-8 minutes. I believe this must be some fluid getting on the exhaust manifolds and burning off, now what fluid it is, and where its coming from I have no idea. I have no fluid drops on the floor of the garage, and the engine was swapped by Nissan dealer at 50k. Car now has 70K. (Idk why it was changed because it was the previous owner). Every time I have tried looking at head cover gaskets, or any oil of fluid that may be pooling in a crevice, I dont find anything.

Any ideas guys?

thanks!

 

Check the valve covers- I bought mine with 80k mi- Valve covers were leaking oil -

You must replace the entire valve cover as the gaskets are built into the valve cover- unless someone on here can chime in-

That is where I would start. Strange issue though-

btw: have you changed spark plugs yet? That will tell you if they are leaking- the plugs will be wet.

 

Valve cover gaskets are not built in, so you can replace them without replacing the whole valve cover.

But, they are a pita to change out.

The spark plug gaskets are built in though.

 

^^ i was about to say!
I would kill nissan if they did that!

No I haven't touched the motor. Just changed the belts since they were making noise. The weird part is it only happens when I turn aggressively. On a normal turn nothing happens. And good Idea, I had forgotten about checking the plugs! Now to squeeze my giant meat clams to take em out...
