Hey guys I am selling my 35th anniversary 350z and picking up a Nismo V1 370z. The car is 6 hours away so I will be picking it up next week. The guy told me that the engine has a knocking/ticking noise and that engine most probably needs to be replaced. Here is a video of the sound, it kind of seems normal to me what do you guys think?

 

You don't say who the guy is-seller, your friend, mechanic or Homer Simpson. There's a lot more to confirm health of a VQ than a YT video. If the seller tells you this ask yourself why.

 

I was just wondering what it could possibly be. The guy is just a seller that I do not know, I am getting the car for cheap because of the issue. He never got the car checked since the noise appeared, he just turned it off and towed the car to his place. Budget wise I am kind of expecting an engine replacement but looking thought the internet I found out that It could be other stuff too.

He told me that it does not knock at idle and starts at around 2500rpm

 

Unfortunately, no one can diagnose it over the internet. If you buy it expecting to replace the motor, I don't think you can go wrong. If you're buying it and expecting to get lucky...not such a good idea.

 

Picked up the car and will tow it to a garage soon, not expecting any answers really since it's another video but if this could help. Kind of think that it is a bent rod and since the car was low on oil also, but at the same time it seems to be sound of vibration from a metal plate
