The engine shot is in there. Either click on the main photo to launch another window and look for it in the thumbnails to the right or - and this caught me out for a while when they introduced it - scroll down the thumbnails under the main photo. The scroll bar for that is a tiny pale thing just to the right of the thumbnails under the main picture.
Its a bit of a mess as just passing the mouse over the main photo does a magnifying glass thing while once you've clicked on it to launch the other window in that you need to click on the photo to do it.
Why oh why can't we look at Classic Cars in Classic Ebay
