Funny sound

[future_R34]

Here's a quick vid of the sound. What's your thoughts?

I fogged the engine later that day so I can't do any t/s now.

Thanks!

Leaking hose on top of a nipple type of sound?

Or a loose / slipping auxiliary belt, which usually can be heard when starting engine.

No belt squeaks at all. Could it be the bov? Or turbo on the way out?

Definetly not bov or the turbo. Start by looking at your accessory belts , how's the tension , any cracks ....I don't remember it making that noise when you had the car over.

All the belts are done(including timing with pit works stuff) and it did make that noise when you looked at her that time cause you said "that's funny, mine don't do that" cause I was freaking out the whole trip home making sure it didn't get worse lol.

I'll check around the belts etc again but I'm pretty sure it wasn't the cause.

sounds cool, leave it

Ha don't Recall it but anyway next year maybe it is best to pull off the intake to the turbo and see if it's spinning freely ...although the sound stops really fast so I don't see it being that . Sounds like what Skym said a vacuum sucking type of sound...I replaced 10 or so rubber hoses so something to look forward to ...

Can get the turbo to exhaust manifold gasket being played like a reed in a instrument (no locking tabs behind the turbo to exhaust manifold nuts, so the nuts come undone due to vibration), but would hear the sound at higher rpm.

Check for gasket leaks on the intake plenum. Such as the aacv

Thought I herd a vac leak somewhere around the fpr while idling, but couldn't find any issus. Didn't look around the back/lower end of the intake tho...... May be next
