Sure is. You will have to clean that engine as shiney as a new penny and the have a really good reaching marker/lead. It is MUCH easier to reach if you remove the heat shield assembly, but that is like pulling hens teeth or getting... well anyway, it's a pain. I was able to read mine with the cleaning method to verify that my engine was a special vehicles high compression version over a standard high compression or low compression version.
Yes, it's a V8. Would it be easier trying to get at it from underneath?
I'm also supposed to make a rubbing of the VIN too, which is right behind the windscreen! I tried on the identification plate next to the bonnet lock, but it's hardly readable. It'll have to do.
