Engine Replacement
When repairs stop adding up, it may be time for a smarter reset.
Engine replacement offers a dependable solution when internal damage, age, or repeated failures begin to affect safety and performance. This service is about more than restoring motion, it’s about giving your vehicle a second life with stability you can rely on.
We had them replace the engine on our 2002 Toyota Echo. It now runs like a charm, and they gave us a three year, 30,000 mile warranty on the engine and labor. We highly recommend Multnomah Automotive!

Engine Replacement Services
A Thoughtful Approach to Engine Replacement
Engine replacement is a major decision, and it deserves careful planning. At Multnomah Automotive, the process begins with confirming that replacement is truly the best option. Our technicians assess engine wear, system compatibility, and long-term value before any work begins. This ensures you’re investing in a solution that makes sense, not just a quick response to a serious problem.
Â
Once replacement is confirmed, attention shifts to precision. Supporting systems like cooling, lubrication, electronics, and drivetrain connections are reviewed to ensure they align with the new engine. This prevents hidden issues from carrying over and helps the vehicle perform as it should from day one. Every step is handled with accuracy, accountability, and respect for your time.

Clear Warning Signs Your Engine May Need Replacement
Some engine problems go beyond standard repairs. Addressing these issues early can prevent further damage and unexpected breakdowns. If you notice several of the signs below, replacement may be the most reliable option:
Persistent knocking or metallic engine noise
Persistent knocking or matallic noises from an engine can be caused by issues such as worn bearings, low or dirty oil leading to poor lubrication, detonation (abnormal combustion), loose or damaged internal components, or problems with belts, pulleys, or the transmission system.
Ongoing overheating despite cooling repairs
Repeated overheating despite cooling system repairs can be caused by underlying issues such as a failing head gasket, a cracked engine block, trapped air in the cooling system, a malfunctioning thermostat, or restricted coolant flow due to internal corrosion or debris.
Loss of power and rough acceleration
Severe loss of power and acceleration is caused by clogged fuel injectors or filters restricting fuel flow, a failing fuel pump, reduced air intake from a dirty filter, ignition problems like worn spark plugs or coils, low engine compression, or exhaust restrictions such as a clogged catalytic converter.
Oil contamination or coolant mixing
Oil mixing with coolant can be caused by a failing head gasket, a cracked engine block or cylinder head, or a damaged oil cooler, all of which can allow fluids to leak and mix within the engine.
Internal damage from timing belt or chain failure
A broken or slipped timing belt can throw off valve timing—allowing pistons and valves to collide in interference engines—or because damaged internal parts such as valves, pistons, or connecting rods can no longer move in proper synchronization, leading to catastrophic mechanical failure.
Repeated engine repairs without improvement
Repair visits without lasting improvement can result from misdiagnosed underlying issues, poor-quality or temporary fixes, failure to address root causes, compounding damage from unresolved problems, or the cumulative effect of multiple worn components in an aging system.
Sudden engine shutdown or failure to start
A sudden engine shutdown or failure to start can be caused by fuel delivery issues such as a failed fuel pump or clogged injectors, ignition system failures like a faulty crankshaft sensor or spark plugs, electrical problems including a dead battery or damaged wiring, or severe internal engine damage such as a broken timing belt or seized components.
Heavy exhaust smoke or strong fuel odors
Heavy smoke or strong fuel odors can be caused by burning oil from worn seals or piston rings, overheating engine components, coolant leaking into the combustion chamber, or an overly rich fuel mixture leading to incomplete combustion.

My car’s tires blew out right near their shop, and they were super helpful in getting new tires in and replacing them within one day. Really helpful, and professional.
Jason was so kind and gave me great advice even though my car was at another shop. He’s honest and sincere, and knows how to get his customers back on the road.
I have been going to Multnomah Automotive for all my car repair needs. Every time I have been there, I have received stellar customer service. I could not have asked for a better Auto Repair shop. Thank You Jason!
Good, honest service. Reasonable prices. Jiffy Lube is right across the street from me, but I still make the 20 minute trip to Multnomah Automotive because of those qualities.
