      It is possible to fit a dump valve to the Astra but it has to be fitted correctly. Heed the advice fro VXRdave, I know Courtenays have had to correct a few in the past , not so much the LEH engine but certainely on the LET. Incorrect fitting causes big problems. Chat with them if you need one fitted.
