Frequently Asked Questions: Auto Engine Repair

How much does auto engine repair cost?
Auto engine repair costs vary significantly based on the specific issue and your vehicle type. We provide free diagnostics with repair and accurate quotes before any work begins. Call (707) 584-7727 for a free diagnostic and estimate for your specific vehicle.
What are signs I need auto engine repair?
Common signs you need engine repair include: check engine light illuminated, engine knocking or pinging sounds, rough idle or stalling, loss of power during acceleration, excessive exhaust smoke (white, blue, or black), oil leaks under the vehicle, engine overheating, poor fuel economy, and difficulty starting. If you notice any of these symptoms, get your engine diagnosed promptly to prevent more expensive damage.
Should I repair or replace my engine?
The repair vs. replace decision depends on several factors: vehicle value, mileage, overall condition, and repair costs. Generally, if repair costs exceed 50-60% of the vehicle's value, or if the engine has severe damage (cracked block, major bearing failure), replacement may be more cost-effective. Options include new engine, rebuilt engine, or quality used engine. Our technicians will help you evaluate the best option for your situation and budget.
How long does engine repair take?
Engine repair timeframes vary by service: Minor repairs (sensors, belts) take 1-4 hours. Timing belt replacement typically takes 4-8 hours. Head gasket repair requires 1-3 days. Complete engine rebuild or replacement takes 3-7 days depending on parts availability and complexity. We provide accurate time estimates after diagnosis and keep you updated throughout the repair process.
What causes engine problems?
Common causes of engine problems include: lack of maintenance (missed oil changes, neglected coolant service), overheating from cooling system failures, timing belt/chain failure, worn internal components, oil leaks and low oil levels, carbon buildup affecting performance, faulty sensors sending incorrect signals, and normal wear over high mileage. Regular maintenance prevents most major engine problems.

We service all makes and models of cars, trucks, and SUVs.
Is a check engine light serious?
A check engine light can indicate anything from a loose gas cap to serious engine damage. A steady light typically means a less urgent issue, but you should get it diagnosed soon. A flashing check engine light is serious—it usually indicates engine misfires that can damage your catalytic converter. Never ignore a check engine light; early diagnosis prevents expensive repairs.
Do you warranty engine repairs?
Yes, we provide warranty coverage on all engine repairs. Specific warranty terms depend on the type of repair and parts used. We use quality OEM-equivalent or better parts to ensure lasting repairs. Our 30+ years in business and BBB A+ rating reflect our commitment to standing behind our work. Ask about warranty details when you receive your repair estimate.

We're also ATRA (Automatic Transmission Rebuilders Association) certified and an AMRA MAP (Automotive Maintenance & Repair Association) Participating Facility with MAP-Qualified Technicians. Our shop maintains a BBB A+ rating. These certifications ensure you receive professional, quality engine repair services.
