Why does my 350z sound like a tractor?
Someone told me to replace my fuel pressure damper, could this be the fix? Just wanting some more opinions before I go out and spend more money on unnecessary parts. I have made two videos of what my car sounds like here:

Yikes!.Do you have oil in your engine?!?
I have also had an oil change and its been serviced recently.
Even my mechanic is stumped as to what it could be. I think he just doesn't want to pull it apart.

Why should your mech be hesitant? He doesn't want labor $$?
Other thought, you got a loose spark plug? Sounds like that too. Does the noise go up with the revs? Disappear? Get louder?
Well, good luck with tracking that down. Sounds like the shid of impending doom, sorry to say.

Doesn't mean the techs remembered to fill the crankcase. (Or tighten the drainplug.) Seen it happen. And that's exactly what an oil starved engine sounds like.

Spark plug, interesting.. I'll add that one to my list.

Okay you have to give us more of the story...
Did your mechanic do an oil change and then this noise started immediately after?
Was the noise always there from when you got the car and just got worse?

Is it throwing any codes?

I have had so many people give me all different reasons why it might be making the noise. Just have nail it down to the source. I have watched a few youtube videos that have the same problem and a lot of them say to change the fuel pulsation damper.

Great reply. I'm still giggling. About your question: It sounds like the noise is coming from the lifters. I believe that these are self adjusting on the 350z, so the problem might be caused by the camshaft.
- Do you know if the engine has ever been over-heated?
- Do you notice a white color in the exhaust?

No, it won't even connect to a computer to show the codes
The noise has been happening for a long time so I cant remember whether it happened after an oil change. It may have happened after it over heated a long time ago.
When I first bought the car it had an overheating problem but then I got it fixed by putting liquid glass in the radiator.

I know how frustrating this can be. Please keep us posted if you find the solution. --Spike

Thank's for your opinions.
I do believe that one of the cyclinders in the engine are warped and may need reboring but whether that is the problem I'm not sure. There used to be white fumes coming out of the exhaust but that was a while ago. Not so sure now. When you say colour in the exhaust do you really mean inside the exhaust like stuck on the inside? or the smoke?
Please Don't throw any more parts at the car until you've confirmed whether or not you're gonna need a rebuild.Also try checking all of your fuses for the no communication issue.Is it misfiring in the video?
It's so frustrating that no mechanic in my area wants to have a look at it unless they pull the whole engine down and charge me a fortune.
