Frequently Asked Questions
Is it worth repairing an older engine?
It depends on the vehicle's overall condition and your situation. We'll give you an honest assessment of repair costs versus vehicle value and help you make an informed decision.
What causes a head gasket to fail?
Common causes include overheating (the most common cause), age, and manufacturing defects. Some engines are more prone to head gasket failure than others. We can advise if your vehicle is at higher risk.
How do I prevent engine problems?
Regular oil changes, maintaining proper coolant levels, replacing worn belts and hoses, and addressing warning lights promptly are the best preventive measures.
What does blue smoke from the exhaust mean?
Blue smoke indicates oil is being burned in the combustion chamber. This can be caused by worn piston rings, valve seals, or PCV system problems. The sooner it's addressed, the less damage occurs.
Can I drive with the check engine light on?
A steady check engine light usually indicates a non-emergency issue, but should be diagnosed soon. A flashing check engine light indicates a misfire that can damage the catalytic converter – reduce speed and have it checked immediately.
