Hi. My '59 plate 110 Limited has today started to make a rattling noise. I first assumed this was the 'box, but after a period of time experimenting with it, I think it might be the turbo, which is a VNT item. If I sit in 3rd gear at around 1800 rpm and gently throttle on and off, it's most noticeable. As I understand it, this is where the turbo starts to spin. However, just to confuse the issue, I checked for play in the turbo shaft this afternoon and can find none. It has to be under load to make the noise, it won't do it when stationary and revved.
The van drives as if nothing is wrong, other than the rattle. However, I'm concerned that if the turbo is at fault and the worst happens, it takes the engine with it.
Is the turbo the most likely thing for it to be? The van's done 47k miles, and has full service history, plus oil and filter changes every 5k miles.
Cheers, Andy.
