Engine Repair near Visitacion Valley, San Francisco

We do engine repair for Visitacion Valley drivers about 8 minutes from Visitacion Valley, San Francisco. Our shop is at 2800 Oakdale Ave in Bayview — family-owned since 1996, walk-ins welcome, written estimate before any work starts. Below is what a engine repair visit looks like when you come from Visitacion Valley.

Engine work is where shop quality really shows. Wrong torque, wrong gasket, wrong order, wrong sealant and you are back inside a year. We do engine repair the way it should be done: diagnose first, give you a real number, do the work to manufacturer spec, and stand behind it. We work on domestic, Asian, and European engines from carbureted classics through modern direct-injection turbos.

What we repair

Misfires, rough idle, oil leaks, coolant leaks, overheating, timing chain or timing belt service, head gasket diagnosis and replacement, valve cover gaskets, oil pan gaskets, intake manifold leaks, sensor replacements, vacuum leaks, fuel injection problems, and more. If your engine is throwing codes or making a noise that was not there last week, bring it in.

  • Misfire and rough-running diagnosis
  • Timing chain and timing belt replacement
  • Head gasket diagnosis (compression and leak-down testing)
  • Valve cover, oil pan, and intake gasket replacement
  • Cooling system repair (water pump, thermostat, radiator)
  • Sensor replacement (oxygen, MAF, MAP, crank, cam)
  • Vacuum leak smoke testing
  • Direct injection carbon cleaning

Diagnose first

Engine repair without diagnosis is parts roulette. We start with a real diagnosis: scan, road test, compression test, leak-down test, smoke test, whatever the symptom calls for. You get a written estimate before we open anything up. We tell you which repairs are critical, which can wait, and what we expect after the fix.

When repair makes sense vs replacement

Sometimes a head gasket job on a 200,000-mile minivan does not pencil out. We will tell you the truth. If the smarter move is to replace the engine or sell the car, you will hear that from us before we start tearing things apart.

Warranty

Most engine repairs we do come with a 12 month / 12,000 mile warranty on parts and labor. Major work like timing chains or head gaskets is covered to the same standard.

Engine Repair questions from Visitacion Valley

Real questions, straight answers.

How long is the drive from Visitacion Valley?+
About eight minutes most of the day. A little longer during 5pm rush on Bayshore.
Do you do smog checks for cars registered to a Visitacion Valley address?+
Yes. We are a CA Bureau of Automotive Repair registered smog station and the state lookup tool will show us.
How much does engine repair cost?+
Wide range. A simple sensor or gasket can be a few hundred. A timing chain or head gasket can be a few thousand. We never quote you for engine work without diagnosing first. The diagnostic fee is a flat rate; the repair estimate comes after we know what is actually wrong.
Can you tell if my head gasket is bad?+
Yes. Symptoms can mimic other things, so we test for it: chemical block test for combustion gases in the coolant, compression test, leak-down test, and a borescope into the cylinders if needed. We do not guess.
Should I just buy a used engine?+
Sometimes that is the right answer, especially on a high-mileage car with a major failure. We will source a known-good used engine, install it, and warranty the install. We will be straight with you about whether it makes financial sense.
