Annoying whistle, 1992 Toyota HiAce engine..

#1 Post by JPB » Fri Nov 08, 2019 1:42 am

Turn the treble right up at the 16KHz+ end of the scale if your sound card allows for this sort of thing as not everyone finds Yoda's new funny noise as annoying as I do. I can hear this at idle, as the video will demonstrate, and it's even audible with the engine cover / passenger seat closed, in spite of the engine's remarkable (for an "old school" veggie burning lump of cast iron) silence in other ways.
Enough writing, please do some listening and tell me, for the love of all things mechanically propelled, what the €£&$ is this infernal racket?
:evil:

JB I didn't go looking for the current fleet, they just sort of followed me home and now they won't leave without an extradition order from the Japanese government..

It's audible enough on the amp & speakers I'm using here. I've covered around 180KM since earlier today and have noticed no change in the pitch or loudness of the noise, I've checked everything that I can think of but can find absolutely nothing that would explain that damned noise.

Tomorrow should yield a solution though, I'm off to buy a decent radio for the van.... :oops:

Solution found! There was a very slight air leak between the air intake grille (four feet up the van body behind the driver's door, marvellous for driving through really deep puddles, or trips down South..) and the surrounding bodywork, the pipework must have been acting like the horn on a mechanical phonograph. Removing the gasket that joins steel bodywork to flexible pipework, adding a thin bead of bathroom silicon, then refitting has brought about virtual silence in the cab, but naturally, this improvement to my driving conditions has also highlighted at least a dozen other noises that I simply hadn't noticed earlier. Imagine; a steel / GRP composite body that creaks as it's being driven :lol: , I thought I'd left that sort of thing behind when I excavated every single kilo of Cataloy from my old FE series Vauxhall VX1800 and replaced the plop with fresh steel.
I still plan to fit a decent wireless set to the van though. It has only slightly less interior volume than the mobile cinema which serves these here parts (when its ownership committee can afford some insurance) and that means that some stupidly large old speakers and a massive, understressed a/f amplifier can also be fitted without compromising sleeping or cooking space. I'll show the Barry Boys crowd what loud music is!
:twisted: ;)
