How to clean dirt and moss from your door seals

If you follow me on Twitter or have seen previous posts on this blog, you will know that for about as long as I’ve owned my SEAT Leon, I have had issues with moisture getting inside the car. For the most part, I have now solved that, by addressing the main problem areas. The one thing I haven’t yet done is to clean the rubber door seals. Dirt and moss will often accumulate on, around, and inside of these seals, reducing their effectiveness.

Parking your car outside in Britain means it is frequently going to get wet, and when it routinely sits it in a place with little sun, as mine does when it is parked on the drive of a more north-facing house, that moisture does not dry up, feeding the growth of moss. If I’m honest, the problem is compounded by the fact that I don’t wash the Leon enough.

Fleet update, January 2019

2002 SEAT Leon 20VT

For the first time ever in my two and a half years of owning the Leon, I calculated the fuel mileage. After a fairly even split of 200 miles of commuting and 200 miles of slightly exuberant recreational motoring, it came in at 33.5mpg. That was better than I expected, and means it would probably not take much effort to be knocking on 40mpg on a run. The only other thing of note this month was capturing a pleasing odometer reading.

Flex disc woes

On most rear-wheel drive vehicles, a flex disc, sometimes called a giubo (which, you may be interested to know, is properly pronounced JOO-boh), is fitted where the gearbox and propshaft flanges meet. Flex discs are designed to help smooth out the transfer of torque between the gearbox and the rear wheels. You can see it in place on my E39 below, with the gearbox crossmember removed, which you need out of the way in order to access the flex disc.

The photo below shows the old flex disc from my car on the left, and the new one on the right. Now, if you’ve been following this blog for any length of time, you will know that I replaced this last March. So why am I doing it again now, and more importantly, why is the old one so distressed already? Continue reading “Flex disc woes”

Improving performance by cleaning and re-crimping electrical connections

A few weeks ago, I replaced the seals on the VANOS unit on my E39. Replacing the seals is supposed to restore low-end power and response, increase fuel economy, and help the car idle better. I can’t say I have noticed any dramatic improvement in how the car runs since doing the job. Granted, my seals were only partially worn, but in the 500 miles I’ve driven in the past few weeks, the only noticeable change has been a slightly smoother idle when cold.
