This vehicle was brought to us without any check engine light but to diagnose an engine oil leak. Diagnosis revealed a leaking oil pan. Upon removing the pan, we found broken timing guide pieces in the pan and in the oil pump pick up screen. To see these images, watch the video to the end.
We also found a mess of the typical coolant hose leak that connects from the expansion tank to the Turbocharger. I would not ever suggest attempting this job without the proper tools. Mini special tool 119630 made by Baum Tools may just be one of the most simple and useful tools on the market. This tool makes the job so much easier.
We also used the factory tool to install the new front crankshaft seal. Always use new camshaft and crankshaft sprocket bolts as they are torque to yield and very crucial not to fail.
To replace the oil pump, we had to remove the passenger side drive axle and support bracket. This is to gain access to the wiring harness for the oil pump.
We hope this video is helpful and thank you for watching. Please subscribe and like.

Great instructional video, how much did the total repair cost?

You can tell this car did not get frequent oil changes by the condition of the cam bearing caps being all dull brown. And yeah, I hate worm gear clamps. Too easy to overtighten and cut the hose, and OEM spring clamps always maintain the same clamping force as the hose expands and contracts during temperature changes and aging.

Thank you very much for this video. What was the mileage on this car? I'm planning to buy one a 2015 Mini (N18 engine) with 62,000 mile on it. So not sure when I have to change the timing chain?

Quick question, i am replacing the timing chain on my n18. I torqued the crank bolt to specs with the loking pin in, but did not have the cams in at the same time. I put the cams in after i torqued the crank bolt and have them locked now. Going to torque the tensioner and cam gears next. Is it acceptable in this order?

I would say that you will be ok as long as the crank remains locked while you are torqueing the cams and installing the tensioner. Since the camshaft adjusters are "free spinning" until torqued down, all the chain slack should roll to the tensioner side once the tensioner is installed. Prior to torqueing the cam bolts, make sure you have the chain pre tensioned. Thank you for watching our video.

Have you guys ever done a timing cover for an oil leak? If so does the head gasket also have to come off or could you remove the oil pan and do it thay way?

No, there is not a separate timing cover. The cylinder head and engine block wrap around the timing chain. There is no need to remove the cylinder head. Thank you for watching our videos.

Wild! What’s the approximate cost of a service/repair like this all in with parts and the labor? I’m an owner of a 2012 R57 Mini Cooper S with an N18 engine (convertible version of the hardtop gen 2 mini). Been well taken care of for 85,000 miles and driven slowly/calmly in short trips by a family member. Now I’m the owner, driving exceptionally sporty once up to operating temperature, and am deep diving to try and figure how to work on my machine. Wasn’t aware of this risk, but the internet confirms timing chains grenade this thing. I’m at 106k miles now. My chief concern was my automatic transmission and soft top for expense planning, but now im watching both timing chain and the turbo. The turbo I feel I can replace myself at my ultimate learning experience. But this…. This seems involved. How much effort is getting to that chain to replace?

Hello, we suggest getting quotes from your local service provider as prices can vary from shop to shop. We also suggest not to attempt this job without the necessary special tooling and experience. A mistake can end up with piston to valve contact and then things get more expensive. Thank you for watching our videos.
