When you hear a valve tapping noise, detect engine oil burn, or sense misfires, your engine may need to be rebuilt. When an engine needs a complete overhaul, you can either replace it (with a new, remanufactured or used engine) or you can repair or rebuild it.
Remanufactured engines have become widespread these days because they have become readily available at competitive prices and most come with a 90-day to one-year warranty. Still, rebuilding an engine can save you up to 50% if the wear or the damage is not extreme. To be able to decide on which option works best within your budget range, consult with your mechanic so that he can provide you with the right options based on your vehicle?s engine type and the specific work around it that is required to bring your engine back to life.
