I am really excited to announce the complete rewrite and recreation of my Chassis Decoder. The original decoder was not particularly reliable and often failed to decode known chassis codes. I have spent a ton of time reworking this one to hopefully address as many issues as possible to allow people to decode their Chassis Codes more reliably.

Reporting bugs:

Please let me know if you see issues with the new tool. This is VERSION ONE, so there almost certainly will be bugs, and if you encounter any, please consider making a bug report:

If you submit a bug with this Chassis Decoder, please include your model year, full chassis number, and the expected results.

Just had one of my pads come apart and trash my drum. Looking at replacement parts and the online pics show a flat faced drum, where mine seemed to have a cone at the hub.

Im fine buying all new hardware, just wanted a quick primer on options.

I would like some help on getting the right wheels and nuts for my '88 1000

Thumbnail

Upvotes

I want the classic Minilite style wheels and there are tons of options out there. I find it a bit confusing at times with all the numbers. My 1988 Mini 1000 has an ET14 and 57,1mm bore diameter. I've read online that getting new wheels also requires getting new nuts and thats whats confusing me a bit, which nuts I need. I have found this set on minispares.com that just has the right nuts included and I am very inclined to buy that set, but since I'm not located in the UK, I'm a bit worried about high import fees since it'll be quite a heavy package. Also Minispares doesn't list the bore diameter, so I dont know if I also have to order center rings or not. The other option that I've found, is a set of Maxilite from SCWheels in Germany. I wont have to pay any import fees on that, since I live in the Netherlands. But the issue here is that I'm not sure which nuts I need to buy with it. I'm also not sure on the quality and look of the Minispares set, its very hard to find examples of Minis that have minispare wheels on them. Any help or insight would be highly appreciated!

Parts advice for the US?

2 Upvotes

Hey guys, recently got myself a mini and have been browsing for parts and accessories. It seems as though minisport might be having some US supply issues as trying to find wheels, exhaust, seats etc are all out of stock and I’m having a hard time finding somewhere else to order from that isn’t extortionate for shipping to the states. Any info would be greatly appreciated!

DIY Help Thump when upshifting

Post image
51 Upvotes

Hi mini pals, question for anyone with some insight. I’ve noticed my 1996 1.3i has started to make pretty subtle thumps when I go up gears. If I pull off the clutch really gently I can get it not to thump but otherwise I hear it. Internet research suggests it’s the engine steady bushes or generally some engine movement when the torque is released. Anyone experience this and figure out specifically what it is? And if so, are these parts I can order and replace on my own easily? TIA.

How worried should I be about this rust on a ’97 Rover Mini?

Thumbnail

47 Upvotes

Looking at buying a 1997 JDM Rover Mini Cooper 1.3i automatic with ~60k miles.

I found rust/bubbling in two places: the lower front wing just ahead of the front wheel, right around the panel seam, and along the bottom edge of one door.

For those familiar with Mini rust: do these locations usually stay relatively localized, or are they signs that I should expect/save for more extensive bodywork down the road?

What hidden areas would you specifically inspect based on these spots?

Mechanically, it’s an automatic with no maintenance records at ~60k miles. I’m planning a PPI, but would also appreciate thoughts on how much of a concern the AP automatic should be at this mileage without documented service history.

Pursue or steer clear? First post

2 Upvotes

Hi all

completely new here but have always loved classic mini’s and recently started looking into buying my first.

I live in southern Germany and came across this post of what is described as a mini mk2 and wanted to ask if people had details on it. Is the dash on the up and up or is it irregular? I Have plenty time and some money to peruse restoration in the years to come but wanted to ask if this is something i should check out or just steer clear of.

hoping for help and advice.

I’m rebuilding a poorly serviced 1275 engine, took the rockers apart to salvage the springs and washers, this is what I found. Rocker 5 I had to cut in half as it was seized onto the shaft. The smallest valve clearance was 3.2mm.
