I just bought another OE type oil filter cap and stole the cage from it to put in the billet one.

I wonder if this is the cause of my random vanos codes despite having maintenance done on the vanos. Come to think of it, how would I have damaged the cage myself when taking it out? The bottom doesn't touch any surface even if I ripped the cage out by force. This would explain why the cage was super hard to remove and it took quite a bit of manhandling, the spring must have already been under tension and the cage literally exploded when I took it out. So it probably wasn't working right to begin with. I ordered a new one.
