As requested these are the photo's I've taken to date.
These show the engine in various stages, some before cleaning, some during, as you can see most traces of gunk have been removed during assembly to help with engine flush at the end.
You will also notice that the head was fully stripped down (new sealant visible) no impressions made on the face and skimmed.
One picture shows the old and new Oil Rail next to the sump, you can see the new unit is much thicker, note it actually fits in reverse to the old unit (see bolt threads).
As mentioned whilst cleaning I tried a few different solvents "white board cleaner" worked great in cleaning the sump and liners. The sump isn't fitted with a gasket and your required to use some sealant paste (again in photo) heating this up provided much easier application to the sump.
Picture of head bolt, clearly shows stamp, I've been advised if it doesn't have the stamp on top not to use and it's a cheap part and will cause issues at a later date.
Also a picture of the items I'm replacing, since the engines done 48K I'm changing the timing belt & wheel, replacing the plugs and filters, I think it makes sense to do it all now, MOT due June.
