Thinking of doing an engine swap on my 1.2 16v Clio campus, it's on 123500 miles, head gasket was going so steel seal was used, so thinking when the steel seal gives up it would be cheaper to replace the engine than buy another car with the limited funds we have. Found some low mileage engines for between £100-£200. how easy is it to do? Or any rough idea on price? Steel seal was only done couple of months ago so I'm hoping I have a few months before it gives up!
