Please help
On a Mini Cooper 2009 r56 engine. Should their be slack in the oil pump drive chain located behind lower sprocket of timing chain. I'm in the process of replacing the timing chain and noticed that the oil pump chain has approximately 3/8" to 1/2" slack / deflection in it, is this normal?

it shouldn't have a ton of slack, but won't be tight like a timing chain. Check if the gears are worn.
