Hi

Are you just running the stock recirculation valve?

You could disassemble clean and rebuild and grease the piston.

Don't know f it's standard or where it is?

if you don't know if its standard or where it is, how do you know its stuck open?

One of the mechanics at Tatton Park told me when I asked him why it was so noisy.
