Troubleshooting Advice / Possible Manifold Leak

[Kiwi_Phil]

I'm pretty sure I have a manifold leak and just need some quick advice. Here are the symptoms,

Fluttery / farting like sound from turbo area at idle. Might be from 4/5 cyl not really sure.

Under boost the noise is huge spool noise and air leak noise, kind of like how I would imagine the turbo boosting into the cabin.

Car seems to still make boost fine and does not come on late or seem to be laggy just very loud - sounds like a fast tractor!

From what I can tell it would be the manifold/turbo gasket (is that what it's called?) do repro etc stock these? Or should I be buying studs/manifold gasket?

I'm just really hoping it's not the turbo!

If you think you have a boost leak, pressure test the system. Do a search to see how to do it.

Have a squizz around to see if you're missing any manifold nuts/studs. They have a habit of going west on RBs.

Yeah I got a new manifold gasket, turbo inlet and 12 new studs today from nissan, I figure if I replace them all its my best bet!

Does anyone use sealant on the ex gaskets?

No.

hell no

if you're going to do all that then be sure to run a straight edge over the flanges, they have a tendency to warp too

just face the manifold and you can use some Hylomar for added insurance for leaks, and use correct sequence/torque on bolts
