Frequently Asked Questions (FAQs) About Engine Service & Repair
Q: How do I know if I need an engine swap versus a repair?
A: If internal damage is severe—cracked block, spun bearings, or excessive metal in oil—repair costs often exceed the price of a remanufactured engine. We provide a detailed cost comparison so you can decide confidently.
Q: What does an engine diagnostic include?
A: We scan for fault codes, capture live data, perform mechanical tests like compression/leak-down, inspect ignition and fuel delivery, and verify cooling and lubrication performance.
Q: Can I drive with the check engine light on?
A: A steady light may allow short trips, but a flashing light indicates active misfires that can damage the catalytic converter. Schedule diagnostics as soon as possible.
Q: How long does an engine repair usually take?
A: Minor repairs—sensor replacements or gasket leaks—often finish the same day. Complex jobs like head-gasket replacement or timing-chain service may require 2–3 days. Engine swaps typically take 3–5 business days, depending on parts availability.
Q: What warranties do you offer on engine repairs?
A: All in-house repairs come with a 2-year/24,000-mile nationwide warranty. Remanufactured engines may carry additional manufacturer warranties—ask for details.
Q: Will an aftermarket performance tune void my warranty?
A: Aggressive or poorly calibrated tunes can void warranties. We can recommend safe tuning options that balance performance with reliability.
