Engine problems range from a simple oxygen sensor to a head gasket or internal failure. For Edmonds drivers navigating the waterfront hills and ferry terminal approach, Tom's B&M Auto has diagnosed and repaired engines of all makes since 1985 — factory-level OBD-II diagnostic tools, not a parts-store code reader. We identify the root cause before recommending any repair, and provide a written estimate before touching anything.
We perform a factory-level OBD-II scan reading live data streams, not just stored codes. A failing mass airflow sensor or intermittent misfire often shows normal codes but abnormal live readings. We diagnose the root cause — not just the symptom.
Written diagnosis before any repair begins. We explain what we found, why it needs fixing, and what it will cost. No work starts until you approve the estimate.
Post-repair road test and re-scan to confirm all fault codes are resolved. Engine repairs backed by our 24-month/24,000-mile warranty.
Engine knocking or noticing engine knocking, misfiring, check engine light, oil burning or loss of power? Edmonds drivers trust Tom's B&M Auto — your local mechanic and auto shop just minutes from Edmonds on Hwy 99. Our ASE-certified technicians handle engine diagnostics, repair and performance restoration for all makes, domestic and foreign. We offer honest car repair with upfront pricing, no hidden fees, and a free multi-point inspection with every visit. Same-day engine diagnosis available — walk-ins welcome — same-day service available for most vehicles. Proudly serving Edmonds, Snohomish County and surrounding areas since 1985.
Engine diagnosis requires the right equipment. We use professional-grade bi-directional scan tools that read manufacturer-specific codes, not just generic OBD-II codes. This matters for European and Japanese vehicles where dealer-level fault codes often reveal the real problem that a generic scanner misses entirely.
We've repaired thousands of engines across all makes since 1985 — from Subaru head gaskets and Honda timing belt service to BMW VANOS failures and GM lifter replacements. We know the common failure patterns for each make, which means faster diagnosis and fewer misdiagnosed repairs.
