2008 Cmax 1.8 Petrol 2nd engine needing a 3rd

[PJR Diagnostics]

hello boys after some advice on this 2008 cmax of mine , i have had it since new and the first engine failed at 75k conrod come out the sump.. bought a second hand one with 56k about 10k ago which is now burning oil like majorly quck 2 litres a week.. the car is lovely, a titanium with the x pack and glass roof and dont really want to get shut instead am hoping i can put a 2.0 petrol engine in it rather than get another one of these crap 1800's ... any advice greatly apreciated.

probably a valve stem oil seal piston rings or head gasket failure , but i am hoping i can just bang a 2.0 in and be away from these 1.8s , cylider number 3 is oiling up causing a misfire..
