Wrenched away for a while on this one last weekend, man that alternator is a beast! Got the gasket replaced but could not figure out for the life of me how to push the bushing / valve on.
Looking at this image
We are meant to push it straight into the "block" with the spring side facing the housing cover, but I did not try to jam it in there. My filter housing already has a protrusion there that would seemingly fit the valve, but I'd been going for so many hours I didn't want to force it and make a mistake.
I can confirm that there wasn't a bushing / valve there when I removed it however. Any tips?
