Smog Mart Inc, Smog and Automobile Repair Center
Tested first, then real options

Engine repair and rebuilds in Sacramento. Repair, rebuild or replace, we tell you straight.

When an engine is done, low compression, knocking, a spun bearing, coolant in the oil, you have choices: repair it, rebuild it here, install a remanufactured engine, or install a used one. We test first, then walk you through the real cost of each for your vehicle before you decide.

What we test and repair

Four options, real numbers

  • Repair. Internal engine repair where it’s practical: head gaskets, cylinder heads, timing components, seals.
  • Rebuild. Performed in-house, with machine-shop work used for the portions that need it. Keeps your original block. New parts installed by us carry our 12-month / 12,000-mile parts-and-labor warranty.
  • Remanufactured engine. We supply and install it. It carries the manufacturer’s or remanufacturer’s warranty where applicable, and usually the shortest downtime.
  • Used engine. We supply and install it. Cheapest up front, most risk, and sold without warranty unless a specific written warranty is stated for the job.

After testing you get the findings and, if you want us to do the work, an estimate for each option that makes sense for your vehicle. The $175 diagnostic is credited toward whichever you choose.

A check engine light or a rough idle isn’t automatically an engine problem. Start with the diagnostic; many “engine” complaints turn out to be ignition, fuel or a sensor.

Common questions

Engine repair and rebuilds questions

How do I know if my engine needs major work?

Persistent knocking, heavy oil consumption, low compression on a cylinder, or coolant mixing with oil. We confirm with compression and leak-down tests before recommending anything major.

Do you rebuild engines in-house?

Yes. Rebuilds are done here. When specialized machining is needed, we use a machine shop for that portion of the work.

Is it worth rebuilding?

Sometimes. It depends on the vehicle's value, the parts cost and what else the car needs. We give you the numbers for repair, rebuild, remanufactured and used so you can decide.

What warranty applies?

Repairs and rebuilds using new parts installed by us carry our 12-month / 12,000-mile parts-and-labor warranty. Remanufactured engines carry the manufacturer's or remanufacturer's warranty where applicable. Used engines are sold without warranty unless a specific written warranty is stated for that job.

The car won't run. Can you help with a tow?

Yes. Give us a call. We work with trusted towing partners and can help you arrange service to the shop.

Do you offer financing for big repairs?

Yes. See the financing page.
