I can't take this pressure on....

... or to be precise my radiator cap can't - seems that fixing the rad leak has identified that the cap is knackered - the spring bit fell off too!

For now I've nicked the one off the 350i but I'll need a new one, any recommendations or are they all the same? What about the pressure - is it 15psi? I think I need one with a top seal too as the SX installation has an extra expansion tank that it can suck fluid back from.

Bump! Anyone know the PSI I need?

I did find this place that looks like the dog's danglies of radiator cap suppliers:
