Engine problems range from a simple oxygen sensor to a head gasket or internal failure. For Shoreline drivers on Aurora Avenue and the SR-522 interchange, 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 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.
