I'm surprised no one has mentioned the GM 2.5 4 cylinder Iron Duke. In 83 to 95 GM A-bodies, the Celebrity, Ciera, 6000, Century, as well as the first generation GM front drivers like the Citation. In the engine bay, everything is very accessible, but the canister oil filter is inside the engine behind a 6" diameter drain plug. It ALWAYS splatters everywhere when that canister filter is yanked out of it's hole.
