Message Hey guys, having a strange situation here. So I performed a boost leak test on the ttz and i found that I have a leak from the dual boost solenoid. There are two solenoids and one of them was letting off air while doing the 5psi pressure test. I believe the unit is suppose to be sealed. The solenoid has an "IN" for the vacuum and "OUT" for the wastegates. Hope someone can give me some insight if this is normal or is the solenoid shot. Getting another solenoid is quite expensive and I don't think the solenoid can be fixed because it is a sealed unit. thanks in advance

The last link is an example of the same solenoid that I'm using. Looking at the picture, there are 2 nipples (that you can't see) that are on the right side of the solenoid and one of those is leaking via the boost leak test
