Broken rocker arm fixed now running rich? M20B25

[curtdogge30]

So my cyl #6 intake side rocker arm broke on me and I just replaced it, got everything buttoned back together and now it's idling super rough, barely shit for throttle response, and it's running rich as oprah....
Is there any way busting a rocker arm would bend a valve? What else could that cause? Plugs are black.
1989 bmw 325ic is the victim

Short answer. Yes, it could.

You can often find out if you have a bent valve by checking the valve clearance, end up with way too much space because the valve isn't fully closed. But if you broke a rocker and reset the clearance, then that's not really going to be possible.

Probably have to do a compression or (even better) leak down test to see if the valve is closing and seating properly. Doesn't take much to cause a problem.
