oil pump drive chain slack
Hi,
I'm new here, working on my girl friend's 2009 mini cooper. It had a stalling/rough idling issue, and a bit of rattle when first starting up. I opened it up and found that the timing chain was loose, so I'm replacing it. When I got the timing chain out, the plastic guides were busted to pieces (the bottom parts, not the guide at the top), and just when I think I managed to pull all of them out, I feel down there an notice that the oil pump drive chain seems really loose.
My questions are: how much slack is the oil pump drive chain supposed to have? Since I don't live within 2 hours of a dealership, where is a good place to order parts online that will ship relatively quickly? Can I get parts from a BMW dealership too, or does it have to be a Mini dealer?
Thanks,
Sean

Ok, Looking at pictures of the pump I assume the pump sits inside the oil pan and picks the oil up from there and pressurizes the oiling system.
It's just difficult to see how it fits inside the oil pan from the pictures.

Highly unlikely, those things get hard a brittle over time. It'll chew them up the they'll get stuck in the oil pump screen. That's were I found some parts. If you have an old tensioner. There's a little trick you can do to them since they operate on oil pressure and spring pressure. I'll send ya a pm.

Hey there, I might be able to help. I have done 3 mini's timing chains, and all of them had tensioner chunks in the oli pump pick up screen. All you need to do is clean them out, and snap the little cover back on. I do not believe that slack in the oil pump chain is significant. as long as the chain won't jump a tooth, you are talking about milliseconds of slack on the oil pump which I can't believe could cause a problem, its not like a critical timing like the timing chain or something more precise. As long as it spins up the pump, you should be fine, all of the ones I did had lots of slack...

Edit: Never mind about the part number, I saw the photos above and got too excited. :(
