BJ 74 resonant noise

[matthias]

Hello,

I've noticed what seems to be resonant noise coming from the intake of the engine. It seems to happen mostly when the engine temp is 1/2 way between cold and operating temperature. Sometimes it also appears when the engine is warm. The truck is fitted with a safari snorkel, so I can hear it well when driving besides the regular intake growl. It seems to be apearing only under load though. Is this normal for a 13BT? I doubt I would be able to hear the noise without the snorkel. The noise is not there when the engine is war

Thanks!

Hello,

II doubt I would be able to hear the noise without the snorkel.
Thanks!

A lot of owners of 4wds report this. I dont think there is a problem ,just keep an eye out for other symptoms
