Question on Turbocharged Engine Oil Cooler Filter Housing Replacing

It's possible to have just oil leaks into coolant, but not vie versa. I have had this happened to my Peugeot 208 GTi which essentially is a N18 Valvetronic engine. Fix it as soon as you see oil in coolant but no exhaust do a exhaust leak test in coolant, because if you don't, oil will quickly destroy your coolant cap rubber seal, then you'll have a bad day from high coolant temperature and coolant explosion when you are forced to switch off the engine by RED STOP sign on your dashboard. Trust me, been there, done that...
