BTW, can you post footage of the sound with a light revving? Have you checked the oil content to see if there are any shavings?

I'd like to trap 125, so that means I want 520-550whp.

I'll post a video later tonight when I get home from work around 11pm. I gave a few videos made of the noise. I changed the oil Friday night after 1800 miles. The oil had 0 shavings in it

May be from the high boost (highest for the vhr ive seen) and the VVEL system is breaking down from it??

could a bad head gasket cause you to lose oil pressure in the heads?

I hope you find the problem

Lifters maybe? But the tech at Infiniti was saying something about VVEL and how it couldn't be the lifters. This stuff is beyond me. I'm not an expert at internals. I'll do some data logging this week and check oil pressure.

Related? Similar noise ?

This is what the Infiniti tech I went to was talking about. The link isn't opening on my phone, so I'll have to check it later. But from what the tech said, it's not the VVEL.

Hopefully its just a bad head gasket and you just need to replace with a thicker/Stronger gasket.

The tech may be thinking vvel since its what our car uses to operate the intake valves which is what I was sort of thinking.

my question is, if it is the actual mechanical vvel components did you just hit the boost limit for this car and how could these components be strengthened.

I would defiantly baby baby the car

guess we will find out soon enough...
