You've hit the list of leaks pretty good. Other known N14 issues are the thermostat and crossover pipe the goes between it and the water pump. Next major problem is the timing chain. When was it done last? The chain is known to cause catastrofic engine failures at this milage if not replaced. Also the pcv system in the valve cover goes bad and oil is sucked into the intake, you can only replace the vavle cover as it is not serviceable. Last on the list is valve seals, they are cooked at this milage and need replacement. They seals along with the cover cause excessive oil usage as mush as or more than the leaks.

 

 

Welcome to the forums! It's unfortunate this is your first experience with the Mini, but from what I've read about the N14s you'll really want to keep an eye on those oil leaks. It might be time timing chain inspection time for yours as well, but I'm not 100% on that so if any other N14 owners can chime in to make sure you're keeping up with the proper maintenance that'd be awesome. Otherwise, good luck with getting the leaks fixed and have fun with it!

 

 

If you replace valve-cover, also replace pcv hose that runs from rear of valve cover to intake. On my 2009 MCS with 135K miles, the said pcv hose had a split in it and was causing all sorts of idle issues...

Good luck!

 

All the leaks are easy over all, just messy. Our Turbo Oil Line Super kit has everyting you will need all in one place with the best parts you can buy! https://www.detroittuned.com/dt-turb...ine-super-kit/

We also have any other other other parts you may need, and i have a cheap seal for your Vaccum Pump if you give us a call!

Faulty PCV system makes pressure to crank ventilation and oil leaks crankshaft oil seal. Very often bad oil filter housing gasket leaks front of motor.

 

OT:
Did the dealer tell you that the car is leeking antifreeze and oil before you bought it? Or was it obvious that it does?

If not, the following may be relevant:

@giorgos Thank you for posting that - I was looking all over because I felt there should be something atune to an implied warranty, but all the information I could find covered lemon laws, sold-as-is, or explicitly defined warranties.

 

 

You're welcome! There is so much inaccurate information and junk on the net that useful information is drowned out...

If that is indeed so (i.e. depending on the state you bought the car in and how the seller declared it beforehand) at least I hope you got a pretty good deal on it.

(even more OT: in Germany, any faults known to the seller must be declared to the buyer. If they are not, the buyer may even be able to force the transaction to be reversed. Also, "as-is" clauses are void and professional dealers automatically are liable for a minimum of six or even 12 months for any faults that were present at the time of purchase)

 

 

 

And the fun just begins! Get a sample of the vacuum line for size and get about 3 feet of hose. Preplace all of the vacuum hoses. That hose in the back of the valve cover that goes to the throttle, replace it or cap it. The caps can be found at the dealer. Just ask the parts guy to show you the drawing for the valve cover on a 2012 or an N18 engine. The cap is in the back where the hose is supposed to be, get 2 of those one for the valve cover and one for the TB. Get an ebay valve cover, they're good. About 60dlls. Check the turbo intake hose for cracks. If it's leaking by the inlet of the turbo or by the PCV metering instrument, you'll get that half lit engine. All these relatively cheap DIY's should get most of the issues that get you that light. You disturbed a few things by doing these gaskets at the front of the engine. Most of these parts are rubber and they crack over the years. They should be easy to identify if they need attention. Good luck. Oh, and get a BSH catch can. There is a video on how to do the install.
