Good afternoon, I did some searching and couldn't find anything specific to very high mileage engines and what to expect. I would like to start this thread to discuss how long a well maintained engine can really last if properly maintained and when we should change "Lifetime Fluids". I have a 2006 Hatchback Non-Supercharged with 195K miles. I just purchased it with 193K and have driven it from Tennessee to DC twice now and it ran beautifully. The only problem I have is losing maybe a quart of coolant on each trip, but I'm addressing that in the near future. The purpose of this thread is to see if I should expect a catastrophic failure of the engine any time soon. I have never rev'd it above 4k RPM and don't plan to as I need a reliable transport for my work. The engine starts and runs beautifully and I haven't lost a drop of oil in 2,000 miles. The exterior almost looks like it was garage kept and had brand new tires and brakes. Just a few rips in the driver's seat from normal wear and tear. The oil is just slightly discolored now and the engine doesn't smoke at all. It was very well maintained as I have carfax reports from about 46K to now by a single owner. They replaced the following:

Oil and filter at regular intervals
Fuel injection service/flush 55k
Spark plugs at 131k
Clutch with pressure plate 132K
Radiator flush 132K
CV Joint boots 134K
Power Steering hoses and clamps replaced to fix leak 134K
Brake pads and rotors 146K
Spark plug wires 165K
Radiator fan 165k
Thermostat 165k
Leak detection pump replaced 170K
New tires 190K

I worry about things like the fuel pump that could strand me if I don't pre-emptively replace it and other items. I know these have timing chains, but should I replace that or the water pump?

 

I have around 195K miles on my 03' JCW R53. Aside from the standard wear items (clutch, brakes, spark plugs, etc)....it's been very reliable. I'm still running the original JCW supercharger, although I did drain and refill the oil in it a while ago. I sent an oil sample off to Blackstone labs a few months ago, and it came back looking fantastic. If you haven't replaced you crank pulley yet....I would do it ASAP. I did mine at 180K miles, and with the shape it was in, I probably should have done it way before that.

I'm just going to keep driving mine....and fix things and they wear out/go bad. I'm sure there are a ton of things I could replace "just because" like the fuel pump, water pump, etc, etc....but at this point, I'm not going to worry about it since I've got a few other backup vehicles.

 

Congrats on picking up a well cared for car. The previous owner invested to keep the car running for a long time. At nearly 200K, you'll essentially want to continue the preventative maintenance regime.

Definitely find out why it's losing coolant, you don't want to overheat.

There's a bunch of known issues with these cars so be prepared. Things like harmonic balancer, coolant expansion tank and cap, 02 sensors, and vacuum leaks will be things to watch out for. Plenty of threads for your reading pleasure to fill in the details.

Here's a good one: https://www.northamericanmotoring.co...nce-guide.html

My kid's (project car) was purchased at 215K miles. It needed a lot of work, but that was on purpose to use it as a teaching experience (see gory details in signature). We essentially did just about everything that could go wrong/worn out along with a few upgrades over the last few years. It should be good to run for another 50-60K, fingers crossed.

 

In my experience, fuel pumps on the R53's don't really fail, or at least it's not a common item (compared to the R56). Water Pumps though are hit or miss depending on the health of the supercharger. I just replaced the WP at 166k miles while doing my Supercharger service, and it honestly didn't really need replacing but if you're servicing the supercharger, you might as well do that as well.

You might get some piece of mind though replacing the Fuel filter, which is a fairly straightforward job, and could be in about an hour or two depending on your skill level. As far as your coolant leak, it could be leaking from the expansion tank as those are known to leak over time. Definitely look more into that.

And timing chains. They don't tend to fail, and if they do, it's quite rare. I would suggest, however, replacing the timing chain tensioner, which doesn't appear to be a difficult job to tackle, although it's a tight space. That would be something to consider if again, you want some piece of mind.

I've owned my R53 for nearly 15 years, and all I've really had to replace on it are maintenance items, minus a couple unique things like both wiper motors failing. Compared to the R56, things like Timing chains, fuel pumps, carbon build up, forced induction, etc are not things that generally go wrong on R53s. Admittedly though, I've been out of the game when it comes to keeping tabs on how different owners' First Gen Mini's are running, but if I could give one piece of advice is drive your Mini. These Minis love to be driven, whether it's a trip to the local grocery store, or a cross country trip. They always enjoy a good run.

 

That's good to hear about the Fuel Pump. Unfortunately, mine did fail and had it replaced. I was also wondering about the Timing Chain and I have heard it's not really a replace item so that's good to hear again.

 

Thanks for the replies, keep them coming. I will likely replace the fuel filter and check the harmonic balancer too.
