Well, the reason I left some of the chaos symbols on the thing was three-fold,
First orks are lazy (when their not killing people) and why would they scrape all of them off if they can delight in stomping on those they stole it from with it still covered in all their symbols and religious mumbo-jumbo. (Note the story from the Ork Codex concerning attempting to infiltrate IG guard positions using stolen tanks so they could drive around running over things, as a giant joke)
second, although some looted vehicles are, very much worse for wear, I kinda approached the project thinking this vehicle was rather "Freshly Looted" so it still retained some of the old actually functioning parts, I will add some orkish details here and there, but for the most part I am going to leave the lower body of the defiler well enough alone, although I might fashion some "replacement" armor pads for the rear legs.
and third, My buddy who sold it to me is an avid CSM player he gave me a good deal, but wasn't quite convinced I could do it so, I left a few of the chaos emblems on their to make mockery of his proper daemon propelled (and well modeled I might add) defiler so that when I play against him we can play clash of the titans...althogh my "Looted Armor" of 11, most likely won't stand up to dreadnought combat weapons. Ah well, such is a war bosses life.
PS, I've never heard of Orks worshiping chaos gods, that sounds kind of strange, The fluff surrounding The Orks writes them as completely immune to the ill effects of chaos (not of the head exploding variety, more just standard chaos god psudo-warp perils) because they were originally a weapon made to eliminate chaos. However, Orks worshipping Korne would be, a rather hilarious subversion, seeing as they can't well receive any of his gifts...
Edit: I was going to replace the central cannon with an old Ork "Lobba" but, The central cannon is a linch pin for the whole upper torso, so I left as is, I may consider "sawing it off" to make it stubbier and less functional looking.
I'm all for playing this game, but you don't have to be a dick about it.
