Expires December 31, 2026. One vehicle per visit. Most cars and light trucks.

Quarts beyond five, diesel engines, and European engines that require a specific manufacturer approval are priced separately — the extra cost may be substantial. We tell you before we start, never after. Some engines must have full synthetic; if yours is one we will say so rather than put the wrong oil in it.

You get a written estimate and you authorize it before any work is done. If the job changes, you get a revised figure to approve.

Machine shop

Most repair shops send machine work away, wait on someone else's schedule, and mark it up. Ours is in the building.

Why it matters to you

The job does not sit in a queue at a third party, and nobody adds a margin on the way back. When a head needs surfacing or a bearing needs pressing, it happens here.

What goes through it

Cylinder heads, blocks, flywheels, pressing and fitting work, and the machining a rebuild needs.

The honest limit

Some specialist work still goes out — and when it does we say who to, rather than pretending the whole job was ours.

Under this roof, on our own schedule

Heads, blocks and pressing work happen here rather than at a subcontractor, which is unusual for an independent shop and is the reason an engine job here does not sit waiting on somebody else's queue. It also means the person machining the part can talk to the person fitting it.

Thao Auto Repair is on El Cajon Blvd in North Park, San Diego, and has been family run for over forty years — started by Le’s father and run by Le ever since. Most of the cars that come through are from the neighborhoods around the shop: North Park, University Heights, Normal Heights, South Park, Hillcrest and City Heights. All makes, domestic, Asian and European. Repair, auto body and a full machine shop are on the one site, which is why a job needing two of the three never leaves the building.

Book a slot

Tell us the symptom. We will tell you the next opening.

The chat narrows the symptom down with you so the call is short and the desk knows what to pull before you arrive. It will not diagnose your car in a chat window, and it does not book for you — the last step is a phone call, to a person.
