I have Belta 2006, 1000cc. Engine started giving problem. Mechanic says rings and valve ceilings to be replaced and advised me to swap the engine. But i am not in favour of this as it will affect the resale due to addition of new engine no. in the book, and also it is a cumbersome procedure. Total cost of engine swapping is 50-60k.

Please advice should I go for repairs or engine change.
