So when I start my engine up and the revs get low, or I change gear or go over a bump it makes a chirping sound. I noticed one of my not very old poly bushes on the top engine steady Has a split in it. I got these from minispares so I would of expected them to last longer. As soon as the engine arms the noise doesn't carry on, is this because the heat expands the bushes?

When I rock the engine there isn't any movement really and that noise can't be heard a little.

Should these bushes last longer than that?

You might check the exhaust manifold. Strange as it might seem, a very slight leak can create odd mechanical sounding noises.

If you have poly bushes at the engine end of the steady, engine heat will cook them, and also the steady will be too stiff. Poly in the bulkhead and the original rubber at the engine end is a better combination.

I am far from convinced that poly bushes are as good as claimed in every application, but they should be ok in the cold end of the steady bar, where there is no complex angular movement.

Oh, and just reading Old Bob's post reminded me of the time my 1962 van chirped. It turned out that the radiator was chafing against the cowling, but despite my best efforts at finding the cause I did not become aware of it until it wore right through. Later models have different radiators and cowlings, so I don't know if the same thing can still happen.

Hmm it is the side of the engine that has the split. Might speak to Simon at minispares to see what he says, as I say I am sure they should of lasted longer than this. I'm sure it is these, it's only started recently and is only within the first few minutes of driving until the heat picks up.
