My question would be for what purpose, versus cost.
Yes, you - and others - are right there. As I said, I was mainly considering it for the sake of curiosity, although would obviously also have been interested for any analysis/commentary about undue crank/bearing/cylinder wear for example. I was thinking that I would pay up to £40 for this, but a quick search shows that I was aiming low as £65-£75 seems the going rate.
I also considered what use I would make of this, and my conclusion was, essentially, none or maybe little. Whatever the result was I would continue driving until it reached the end of its life, but if the result had been very good, then it might have prompted me to perhaps pay for an undersealing treatment. In spite of being 17 years old, the car is , apparently , in excellent condition, with no signs of rust and none noted from inspections, so it might be worth making an investment in preserving the body if the engine is in good condition. Although living in the Alps means four+ months of snow, the roads are usually clear , no salt is used and humidity is low .
2008 1.8 Z18 XER petrol, manual box.
My driving style is restrained, seldom hit 3 500 rpm/75 mph, minimum drive usually 12 miles, but bulk of miles added on holiday driving when it's 100 - 200 miles per day (summer/autumn ) and practically no stop-start driving at all. The only oddity here is that I live at 1 400m altitude and can only go up or down:: down to the valley town means a drop of 1 000 m, so every return home means that the engine always reaches 90C. Only engine repair during my eight year ownership was, in fact, a thermostat two years ago. Annual oil-change with recommended oil and quality oil-filter ( Mann ). Taking all that into account, is this engine known for longevity, meaning should I consider the undersealing more than I have been ?
Freddy: as far as interpretation of report goes, I think you would need to investigate individual providers to see what they offer and I only noted the first pricing page.
