Not really sure what to do. £1400 will get me a rebuild from a company but im not sure i fully trust them . £450 will get me a lower mileage engine which i can transplant and i fancy doing it myself will be my first take out and put in. Get rid of whole car and get another maybe 3 door with leather maybe lower mileage. what should i be paying for chains to be done as i think thats what is making the noise. what do you guys think is the best direction?
