I think my BCA is fine. It'* the wastegate rod that catches.

The wastgate butterfly shaft? Or where the BCA 'hooks' into the foot?

You can lightly oil the butterfly shaft on each side of the SC, but it'* alot easier to do with the SC off the car.

Yes, the shaft. Doesn't come out?

Not without removing the SC from the car. But at this piont, that gasket isn't baked on, so you can. I'd just lube it personally. Might take some time to work the oil in from the bushings, but it might work fine.
