Hi tombo1984,
after 15 minutes of research I couldn't find any hint within your threads or posts, what engine your "1.6" is at all.
Diesel? Petrol? LPG? What construction year?
Check with your dealer whether a replacement engine (including installation) won't exceed the residual value of the vehicle ...
Sad but true, my former Altea blew it's engine after 13 years and even replacement with used parts, let alone a whole engine, would have been way too expensive because of labour costs.
