Recently I was suspecting boost leaks because the boost gauge never reached the yellow zone, only around 12am. Without a boost leak tester I was only able to manually verify parts. First I thought it's the AMAL valve but testing it with 12V it seemed to work properly. I've recently replaced the intake manifold union and cleaned the intake so I expected it to be ok. Finally checked the blow-off valves and found a broken membrane in one.
This causes a leak from the intake manifold (through union part no. 5) back to the pipe after the air filter. It's neither good for the turbos since the valve never opens.
Is there a recommended aftermarket valve instead of this weak looking plastic Bosch (0 208 142 102)? Same functionality (no atmosphere dumping), preferably black to blend in. I was checking the Forge ones, FMDV008, pretty pricey but replacing the turbos would be even pricier.
