Pine Valley Auto Repair has held its Alpine Boulevard location in Alpine since 1996, operating as an incorporated general repair facility with a four-technician crew covering engine diagnostics, brake service, muffler and exhaust work, and wheel alignment. Tire replacements and rotation schedules coordinate with Family Auto Service farther west on Alpine Blvd, where the two shops share a referral corridor anchoring Alpine's primary commercial strip near the I-8 interchange. The shop holds BAR-registered Smog Check Test-and-Repair station credentials, including diesel-opacity testing for trucks and older CARB-regulated engines common in East County San Diego's rural fleet. Engine installation, exchange, and rebuilding services round out the mechanical menu, handling head-gasket failures, timing-chain replacements, and long-block swaps across domestic and import platforms. Collision-related mechanical damage—bent suspension arms, cracked radiators, misaligned subframes—routes through the shop after structural straightening at Lakeside Collision Auto Center on Woodside Avenue, which handles the frame and panel work before returning the vehicle for mechanical reassembly. The diagnostic bay runs OBD-II and manufacturer-proprietary scan tools to isolate powertrain, ABS, and SRS fault codes before authorizing any parts replacement.
