I don't know if anybody saw this weeks Wheeler Dealers on Discovery or caught it on Killer Hertz's very useful link thread but I was fascinated by the engine clean up done by Edd China on the Jag XK8.
For those that haven't yet seen it, they take a late 90's XK8 circa 80k on the clock and Edd puts it on a spectrum analyser clocking up about 1% carbon monoxide (not bad) and a whopping 540 ppm in hydrocarbons.
Then he wheels out this machine which looks like an air con topper upper, which forces highly refined fuel through the engine under pressure. It uses separate solutions for both the pre and post combustion chambers. The actual fuel tank is disconnected so it purely runs on the refined mixtures for about an hour. The object of the exercise is to dramatically drive out the carbon deposits that have built up over the years.
At its conclusion Edd bangs it back on the analyser and records a 50% reduction in CO and hydrocarbons of a mere 76 ppm. He mentions that it's a fairly new process that should cost about £70 at a garage.
Couple of questions, the first being does anyone know where to get it done and secondly is it really as good as it sounds or is it a bit of that 'snake oil' that sometimes finds its way over the Atlantic from our American cousins.
If it is as good as it sounds, for people like me with fairly elderly cars I would have thought it would be a worthwhile exercise, especially at MOT time.
