Engine Repair & Diagnostics

Three weeks ago, a customer from Collingdale called us panicked. Her Honda started making weird knocking sounds on her way to work. She was scared her engine was done for and couldn't afford a new car. Turns out, it was just bad spark plugs causing pre-ignition. Cost her $180 instead of $8,000 for a new engine.


That's why we do thorough engine diagnostics first at Briarcliffe Auto Service. We've been fixing engines in Glenolden for over 38 years, and we've learned that most "engine problems" aren't as bad as they sound.


Complete Engine Diagnostics


Our computer diagnostic tools can read error codes from any car made after 1996. We check everything, including fuel injectors, oxygen sensors, catalytic converter, and mass airflow sensors.


Common symptoms we see from Folcroft to Norwood:


  • Check engine light won't go away
  • Rough idling at stop lights
  • Car shakes when accelerating
  • Poor gas milage suddenly
  • Strange exhaust smoke


Engine Repair Services


We fix all types of engine problems. Most repairs we do same day or next day. Here's what breaks most often in this area:

Timing Belt Replacement - Honda and Toyota owners in Glenolden know this one. Timing belts should get changed every 60,000-100,000 miles. We see too many engines get ruined when people wait too long.

Head Gasket Repair - Usually happens to cars with over 150,000 miles. Especially Subarus around here. White smoke from exhaust and engine overheating are the main signs.

Fuel Injector Cleaning - Winter gas in PA clogs these up. Your car will start rough and get terrible gas milage. We can clean them or replace them if they're too far gone.

Coolant System and Overheating


Summer heat kills engines fast around here. We replace radiators, water pumps, thermostats, and radiator hoses. If your temperature gauge goes into the red zone, shut off your car immediately and call us.


Last July when it hit 95 degrees for a week straight, we got 12 calls from overheated cars. Most were just low on coolant or had clogged radiators from road salt buildup.


Oil Leaks and Engine Seals


Pennsylvania winters are rough on rubber seals. Oil leaks start small but get expensive fast. We fix valve cover gaskets, oil pan gaskets, and rear main seals. If you see dark spots under your car in your driveway, don't wait.


Transmission Problems Connected to Engine


Sometimes what feels like engine trouble is really transmission problems. We diagnose both. Transmission slipping, hard shifts, or delayed engagement often happen together with engine issues.

  • Is it safe to drive with my check engine light on?

    It depends on how the car is running. If your engine light is solid (not flashing) and the car drives normally, you can probably make it to our shop. But if the light is flashing or blinking, that means serious engine damage is happening right now. Pull over and shut off your engine immediately.


    We've seen too many people ruin their engines by driving with a flashing check engine light. A $200 repair becomes a $3000 engine rebuild real quick.

  • How do I know if my engine needs major repair or just maintenance?

    Here's the difference: maintenance fixes and prevents problems, major repairs fix damage that already happened.


    Maintenance stuff like oil changes, spark plugs, and air filters cost $50-300 and keep your engine healthy. Major repairs like blown head gaskets, timing belts, or engine rebuilds cost $800-5000 or more because something broke.


    If your car starts rough, makes weird noises, or has white/blue smoke from the exhaust, that's usually major repair territory. Bring it in quick - waiting makes it worse and more expensive.

  • How long do engine repairs usually take?

    Simple stuff like spark plugs or sensors - same day, 2-4 hours.


    Bigger jobs like timing belts or head gaskets - 2-3 days or more because we have to order parts and do the work right.


    Engine rebuilds or replacements - 5-7 days or more.


    We'll give you a timeline when we diagnose your car. If it takes longer than expected, we call you and explain why. And if you need a car while yours is being repaired, we offer rental vehicles on site.
