I was out with the Brit-car club on a 120 mile drive yesterday and early on was assaulted with a really annoying VERY high-pitched squealing rattle-like sound. Mile after mile for nearly the entire first hour of intermittent driving.

At exactly 2,600 rpm regardless of speed, accelerating/decelerating or gear it comes and goes sounds like it's coming from the camshaft, exhaust manifold, intake leak, rocker shaft, tach cable.......

The damned mirror on the dashboard!!!!!!!! The glass rattled in the gold holder for the first time in nearly 3,000 miles - at exactly 2,600 rpm..

It helps to put o-rings or Thackeray washers under the mounting screws.

I also had a similar problem in a MGBGT and it turned out to be a garage remote that I screwed to the top of the rear view mirror.

That's funny, but at least you figured it out. Reminds me of my trip home after buying my Coupe sight unseen. A 650 mile trip home with an unproven British sports car you imagine all kinds of strange noises. When I was on the north side of Lake Michigan, which i it's self is fairly desolate. I keep this high pitch intermittent noise but couldn't place my finger as to where it was coming from. Well after a few miles of worrying my head off about a bearing seizing I realized what it was. It was my cell phone under a pile of stuff on the passenger seat, my wife was calling to see how it was going. After I hung up I had a good laugh and didn't worry as much on the rest of the trip. Of course that was after I heard a loud thump on the underside of the car and didn't realize that the pin for the clutch slave cylinder removed itself. I found out pulling into the motel parking lot. but that's another story.

ah - maybe that's what mine is...

I get a metallic tinkling sort of sound at certain revs in the interior. At first I thought it was a valve in my radio but removed that. Then I thought it was the split pin in the clutch slave, then fire-extinguisher pin but no...

I had an annoying noise at particular revs which I eventually traced to loosened rivets on the bracket on top of the windscreen into which the soft top locates. Cured with a small drop of araldite.

I had the same symptoms with my MGA. It drove me crazy trying to find it. Rev the engine up to about 1800 rpm's and it would buzz. Raise the bonnet to look for the source and the buzz would go away. Finally found that the bonnet mechanism return spring in the front was the problem. I placed a sleeve of thin rubber tubing around it and have not had the buzz since.

Hey Gary...what are 'Thackeray washers?'

"It helps to put o-rings or Thackeray washers under the mounting screws."

I guess if one wants to be real sure, they'll use a thackery washer and araldite.
Two new words I just learned today.

When I first put this car on the road, the driver's side trunk (boot) hinge pin rattled. Damned aggravating.

I cut a 1/8" piece of cork gasket material and put it underneath the mirror mount where it is sandwiched between the mount and the dashboard scuttle.
