squeal at high revs

[John the sparky]

I have nearly worked my way through my tuit list......

so it is only natural, that with 'repaint the towbar metalwork' as the last thing on my current list..... I should now get a squeal at high revs....

it doesn't happen all the time, and only up at 3750 to 4000 revs.... so I sort of notice it when trying to pull away sharply or overtake, my first thought was belts.... but then I thought it could be alternator.... or possibly turbo, or an airleak on manifold or turbo.....

then I went to bed and thought I'd ask on here before opening the engine cover

any tips or pointers received with thanks

No 1 exhaust manifold stud? The one that's visible at the front of the manifold, possibly won't now be there.

Thats what it was on mine and I was lucky my local garage did it for £30.00 in about an hour.

same on mine needed 2 and both needed helicioling Ok NOW so of to cornwall this weekend

been and looked and yeah, no 1 manifold stud.....

so I'll see if I can get a sensible price at a garage..... can't really muster the enthusiasm to do it in the evening


cheers, and thanks
