Noisy Snorkel

[ptcb]

Hi Guys, my 2005 3.0 Patrol is making a rumble through the Snorkel(factory Nissan one). It's kind of like a resonating burble at idle and you can still hear it whilst driving! Any Ideas?

Do you have a catch can fitted ? may have a fair bit of blowby . how many kays ?

No, no catch can fitted and not quite 120000k's. Fuel efficiency seems right and car running quite well!

Check that snorkel is firm try placing rubber or foam between throat and body.
I think from memory they vibrate from sucking air not 100% but have heard
some are very noisey, it can be fixed though Tried a search???
While its idling try moving it to see if noise changes

Have asked this before. Have simular noise. Had ARB listen to it, they seem to think it’s normal.

I find you get a bit of a rumble not as much when you do some engine braking :)

When I had the D22 Navara with the ZD30 there was a little blow back so there wasn't suction 100% of the time. ARB said it was normal so dunno if its the same kind of thing.

Expect it to be a little noisier than without one.

I had a look through your forum record Janderson and that is what it seems to be doing with mine. Will get the tools out and check under the guard as I have already checked the obvious.
