Thanks to a tip from "Terryfied" (onya Terry) I seem to have solved a serious noise
issue on My 99 TD 3.0 Jack. Best described as a "whipper snipper" going hard, when the engine was under load and over 2000 rpm, the noise was on the passenger's side with nairy a hint out the starboard window. This suggested ruling out the turbo so I started hunting around the exhaust system. But Terry put me onto the intake as a possibility; specifically the
snorkel (fitted 7-8 months back in metro
Adelaide). Taking the ram head off, I found a huge washer (a restrictor in fact) . This washer would have cut the
snorkel intake area by at least half in my view ! (will do the maths later) - I whipped it out and the "serious and somewhat worrying" noise hasgone!
My view on this is that my Unifilter was already compromising the intake to a degree and this restrictor just made things worse. I rang Safari and they tried to fob me off back to the dealer for comment (for this read "clear off you fool - our dealers know everything"). I persisted and eventually got onto a "David" who gave the impression that he had better things to do than talk to me! His short response was that the restrictor is needed for sound dampening and that we would not have it in the kit if it was not required !
Oh
well....... after having the installer lose a couple of clips that can't be bought, and to have the
snorkel's maker give me the impression that he regards me as a nuisance, I'll just store that knowledge away and advise my contacts accordingly.

Banjo,
didn't see your original post with Terryfied (if there was one), but can you describe where the big washer or restrictor exactly was. Just took off the ram head, had a look in it and down the barrel of the
snorkel and saw nothing. I had safari installed about the same time as yours I would think, maybe a bit earlier, and have got what I would more describe as a serious hum between about 2300 rpm which disappears after about 2800 rmp. Put it down to
snorkel vs guard vibrating with resonance, but interested in this washer thing. One thing that made a bit of a difference was the Hiclones I fitted but they soon got pulled out and money back after they did squat.
