Well, oil contamination is not a real problem, as ....
many boats does have a siphon killer, isolating any possible returning water, so it would be a double measure against the possibility. What really deny you using engine intake, is the strong negative pressure created by your engine raw water pump. Regardless the engine, this is always a big negative pressure on your "T". In case you make it, your entire running hoses, clamps, attachments, and all your gear at the watermaker, should have strong dimensions to stand such pressure. Your installation would have to be such a type of engine cooling system, rather a simple transparent and easy for inspection system. Even installing a check-valve, just imagine the amount of power to break it in, your poor pour would have to do. Sounds to me like those guys diving at 10 mts, thinking they could suck down air from a simple hose. Give up, and find another hole .....
