2009 Clubman JCW R55
Anybody have any experience changing an oil pump, chain and sprocket. What all parts and gaskets do I need? What are the steps involved.
Thanks!

Keep in mind you will need to lock the cams and set the timing as you will need to remove the bottom crank bolt to remove the crank sprocket and chain for the oil pump.
This is why we do the chain for the oil pump when we do the timing chain.

Otherwise you remove the oil pan and pull the pump from there.
