Hi guys,

My 370Z now has about 350 miles on it and I am hearing what I think is a piston slap noise when the car is going up hills especially when in neutral while waiting for the gate to open.

I am not 100% sure it is a piston slap problem but it sounds like it or similar to it. What else could it be?

That has me worried because I am scheduled for lots of changes tomorrow as I am driving to the Stillen shop in Costa Mesa. I would not want the Nissan Dealer to tell me it's because of the changes I made that it's happening even though it is happening before any changes.

Anyone has a clue about what the noise could be?
