Engine Repair & Rebuilds

Misfires, oil consumption, overheating, timing components, head gaskets and full rebuilds — diagnosed properly before a single part gets quoted.

The approach

An engine problem is the fastest place for a shop to start guessing. A misfire code points at a cylinder, not a cause — and replacing coils, plugs and injectors one at a time until the light goes off is how a $200 repair turns into $1,400.

We don’t work that way. Every engine job at Cityline starts with actual testing: live data, compression and leak-down where it matters, fuel trims, and a look at what the vehicle’s history is telling us. Then you get a written estimate for the repair that fixes it — once.

What this service includes

  • Misfire and rough-idle diagnosis with live data, not just code readings
  • Timing belt and timing chain service, including tensioners, idlers and water pumps
  • Head gasket replacement and cylinder head work
  • Oil leak diagnosis — valve covers, rear main seals, oil pans, timing covers
  • Cooling system repair: radiators, water pumps, thermostats, hoses and fans
  • Intake, exhaust manifold and gasket replacement
  • Complete engine replacement and rebuild when the math makes sense
Every engine repair job at Cityline includes a complimentary multipoint inspection and is covered by our 2-year / 24,000-mile warranty on most repairs.
Warning signs

When to bring it in.

Any one of these is worth a phone call. Most of them are cheaper to fix now than in three months.

01

Check engine light with a misfire

P0300-series codes, a stumble at idle, or a flashing light — which means stop driving and call us.

02

Overheating or losing coolant

Temperature climbing in traffic, sweet smell, or coolant you keep topping off with no visible puddle.

03

Ticking, knocking or rattling

Especially on a cold start or under load. Noise is the cheapest warning an engine ever gives you.

04

Burning oil between changes

If you’re adding a quart every 1,000 miles, something is going somewhere it shouldn’t.

05

White, blue or heavy grey exhaust

Each color points at a different failure — coolant, oil, or fuel. All three are worth diagnosing now.

06

Sudden drop in power or fuel economy

Often the first symptom of a timing, compression or sensor problem that gets expensive if ignored.

How we work

Diagnose first. Quote second.

1

Verify the complaint

We drive the vehicle and reproduce what you’re describing before touching anything.

2

Test, don’t guess

Live data, fuel trims, compression and leak-down where relevant — we isolate the failed component.

3

Written estimate, your call

You get the finding, the fix and the number. Nothing proceeds until you approve it.

4

Repair, verify, warranty

OEM-quality parts, a road test to confirm the symptom is gone, and 2 years / 24,000 miles behind it.

Questions

Engine Repair, answered.

We’ll give you the honest math. If the repair costs more than the vehicle is worth or the rest of the car is at the end of its life, we’ll say so — we’d rather lose one job than sell you a repair that doesn’t make sense.

Most timing belt services are a one- to two-day job depending on the engine. We almost always recommend doing the water pump, tensioner and idlers at the same time, since the labor is already paid for.

No. A flashing light means raw fuel is going into the exhaust and you can destroy a catalytic converter in minutes. Pull over safely and call us at 972-442-0099.

We use OEM-quality parts on every job. On internal engine components we spec the part the manufacturer engineered for that application — this is not the place to save forty dollars.
