Hi, thought I might try and change the oil for first time, but for the life of me, can't find the sump plug. I have been under the van,(and yes I did look in the rear end

taken off the engine cover on the underside (god!! that's another story!!) Have tried to move further up underneath the van but am a bit limited without ramps. Can any one confirm that the plug is indeed in the engine (underside) cover before I take it off again.
Further confession, I couldn't see the oil filter aswell
Bought this van, with the full intention of learning the basic stuff, but with a lack of manuals available, I am a bit stumped
Cheers
