SOunded ace on the calibra and the corsa, but astra sounded poop in comparison tbh
Z20LET's Have a different dump valve to the C20LET, hence why they make 2 different valves for these engines....hence y i have the dump valve specificly designed for my engine.....i drive about 80 miles a day and have not had any "juddering, hesitance" and it idles fine, tbh it runs exactly the same as it did without it. there was only one dump valve manufactured for the Z20LET and that was the Bailey DV26 "D"

its nothing to do with the valve i assure you. Regal orignally fitted mine when previous owner had it.
If you do a search on AOC you will find anyone who has gone from DV back to the original REcirc valve has reaped the benefits

they definately sound odd on Z20lets. Not as much of a pstish, rather than a silent but large volume fart
