Dual-port wastegate valve stem leakage
Is it normal for a dual-port wastegate to leak past the valve stem on the lower half? I have two different external dual-port wastegates (both are well used) and they both leak past the stem when I put compressed air (<25psi) on the lower half. The upper half is airtight on both of them.
