I'll give him a call tomorrow.
As above, I replaced the crank sensor on mine, and took two goes until I realised the ebay ones were crap. The repco ones are the same brand as the ebay crap.
Went genuine. no more troubles.
The ebay ones I got would be ok at low speed but when I gave it heaps, they would fail. Not "miss" but die completely.
I noticed that the sensor can sit fairly close to the steel vanes in the harmonic balancer. If they were hitting the sensor it might make the noise you describe. If you pulled off the harmonic balancer, you would be able to see where its been rubbing.

You said "i have checked that the hamonic balencer was tight and not loose..." The balancers are apparently put on with no lubricant and the way they fit they're usually really tight and a near nightmare to get off. Have a look at the rubber on the front around the inner and outer edges - if it has small cracks in it it's on its way out. If the rubber splits, you'll notice it as it flaps around and causes a racket.
i havnt taken the harmonic balancer off yet but i can say it doesnt wobble or anything when running with or without the fan belt on

Dont put your details up here. Let me contact my mate first. I tried to call him today but no answer (on any of his numbers) it's been a while since we spoke. He does some work for my old company from time to time, so I can call them tpo get his latest number if I cant get through. I "think" he was badly affected by the 2018 fires as well, so he may have changed his number. Leave that with me.
If you have done the sensor on your supercharged VX, as far as I know, the standard one should be the same?
Do you have a meccanic's stethoscope? Fairly cheap and can pinpoint odd noises.
With the belt off, where does the noise come from?

Who diagnosed it? And what did they say about it?

sapphire marine and auto and the said the noise was actually coming from the back of the motor and it was a cam shaft thrust plate and it was rubbing and its going to just stop while driving so dont drive to far and once it leaks oil thats when the motor is just going to stop. i have another standard vx and a vx super charge but would cost around 1400 to swap motors over as he said once this thrust plate goes theres no point fixing it

How long has it been making the noise for? Does the noise go away if you rev it?
When you start it, does the oil warning light go straigt off or does it take a while?
When was the last oil and filter change done?
