  1. Tools required for engine rebuild?

    I can’t put this off much longer, before I start I wanted to collect the things I need. We’ve all been there, half an hour in and work stops because you need some threaded bar of a certain size or a particular spanner (usually something massive) that you don’t have!! Assuming I need new valves...

  5. Water ingress in footwells around centre console

    Afternoon all Apologies in advance for the long read, but as you'll see, I'm confused . . . . . . so I've found water under the front carpets of the Smart - which from what I've read isn't all that unusual - but what is unusual is how it's dispersed. The majority of the water is around the...

  7. Headlamp dipping direction?

    Just been adjusting my headlamps and noticed there is a little arrow on each glass. The near side passenger one points left (to the near side), but the offside drivers one points right. I thought they should both point left to indicate that they both dip to the left as expected of a normal...

  8. Exclamation Smart 450 Oil Type

    Hello all, I am using full synthetic oil 15W30 for my 2003 Smart 450. I am living in Cyprus where you can tell is a hot climate (over 40 degrees in the summer). Is it okay the oil I am using or should I change it? Waiting for your answers, thanks.

  9. Brabus Engine Quiz

    Just what are the differences between the 700cc Brabus engine and the regular 700cc engine? This is what I reckon, but what do you think? Turbo – Different TIK pipe - Different Injectors – Different ECU Map – Different Exhaust – Different Gear ratios – Different?

  16. Chassis end caps good/ bad?

    I've seen (ali express) plastic "bung hole" cap ends which made me wonder, useful / aesthetic ..or not? I'm quite keen to limit water ingress, but a steel tube with a bung in of that diameter can in theory get "wet" inside based on general seasonal conditions & environment, so a bottom seepage...
