It just started happening tonight. I was coming towards a intersection in the turning lane. The light stayed green so I just slowed down and down shifted. As I came around the turn I acclerated and shifted into the next gear. That's when I heard the noise. The best way I can describe it is a fluttering noise and almost similar to how loud the injectors are on these engines, but this was not the injectors because I could also hear those. The noise doesn't fade out and doesn't go faster or slower no matter how much I push the gas down. It starts up as I'm acclerating and stops at around 3,500RPM.....

 

Is this for the Nissan in your sig?

Your valves might need adjusting. When you downshifted, how high did you rev the engine?

 

i would say valves.

 

2,500 I'd say.

And yeah it's for the Nissan. I've got 32k miles on it also.

 

How would I adjust the valves when I don't have retainers and rockers?
