Snagged 09 clubman s (130k miles) at auction and knew it was most likely a timing chain issue from the picture and doing a small amount of research that it's a fairly common thing on these.

After getting into it further, I've come to a few conclusions --

It had the timing chain done fairly recently along with a new turbo put on...probably within the last 20 minutes it ran or so? Old turbo was probably sucking oil as the intake valves and the cylinders were all dirty but the exhaust valves were clean.

What did it in was a camshaft bolt shearing (overtorqued...way overtorqued) and falling into the timing chain (breaking it) and it bent two exhaust valves, but my guess is that this was done right after the new turbo was put on as if it'd run for any amount of time it would have cleaned up the valves and cylinders a bit.

Anyway, bought the timing tools, timing chain, intake & exhaust valves, new gasket kit...and noticed the oil pump chain was super slack, so ordered a new one of those too (lost one half of a valve keeper too, that sucked, so had to order a new one of those...). Why I'm in here, is there anything else I should be doing for fun or maintenance?

Waiting on the keeper and the oil pump chain right now, but should have them by end of week to put the thing together this weekend.

First two pics are how I bought it, was a clean title no accident so that's a plus (had the valve cover and plugs etc in the back)

 

Maintenance wise if the turbo oil line has never been replaced, I'd go ahead and do that. Detroit tuned sells a super kit with a better engineered oil line to prevent leaks in the future. Additionally, the oil filter housing gasket and oil cooler gaskets are common failure modes so I'd go ahead and replace those too (the OFH gasket comes in the super kit but oil cooler gasket does not).

 

The carbon build up on the intake valves is from the Positive Crankcase Ventilation system, this is common, especially in the N14 engines. They need a carbon cleaning about every 50K miles.

Blocking off the rear PCV line and installing an oil catch in the turbocharger side PCV line will help prevent this.

 

Thank you both for those recommendations, didn't know about that detroit tuned site before either so that helps with parts as I was just sourcing everything off ebay so far. Both really reasonable and I'd seen the oil catch can on another site as well and now that I know from DneprDave that the carbon build up happens normally and it prevents it that seems like a good investment as well.
