Whistling Troopy

What tune's it whistling ? :))

I had a problem with a hole in the manifold once that produced similar results.

Is it coming from the muffler?
Maybe there is heaps of soot in the muffler causing a restriction, hence the whistle?

Just a thought

Probably doesn't apply to your much younger diesel Troopy, but our older petrol one had a habit of pressuring (don't know if negative or positive pressure) its fuel tanks, resulting in whistling fuel caps. Might be worth checking out as it seems the faster you draw fuel from the tanks the louder your whistle - easy to check by just removing/loosening the cap/s.

What sort of electrical load at the time....alternator?...silverback

When we installed the reversing camera we got the same noise - couldn't work it our for a while - it was coming from the speaker in the LCD screen.

Hi Agroe,
My old 80 series pet4.5 used to whistle as a few revs came on...was the exhaust mainly the muffler. Got a new system, noise never returned.

My son's mate has a non turbo troopy ute and his whistle comes from a small air leak in the snorkel

thanks for the replies it soundslike the exhaust. but reluctant to replace on off chance. i thought about snorkel but the noise is defitnitly at the rear. Would a egr valve do it. thanks Agroe
