The head gasket seals the junction between the engine block and cylinder head, containing combustion pressure, coolant, and oil within their respective passages. A blown head gasket can cause coolant to leak into the combustion chamber, oil to mix with coolant, compression loss between cylinders, or external leaks. At Clutch Automotive, we use block chemical testing, coolant pressure testing, compression testing, and leak-down testing to confirm head gasket failure.
Head gasket failure is one of the most serious engine problems and requires thorough diagnosis before committing to an expensive repair. Spokane's freeze-thaw cycles can stress head gaskets, and overheating from any cause can warp the cylinder head and compromise the gasket seal. Subaru EJ-series engines, certain GM engines, and some BMW designs are particularly prone to head gasket issues, and all are common vehicles in the Spokane area. Call (509) 487-0161 for a quote.
What to Expect from Head Gasket Diagnosis
- 1
Symptom analysis
We evaluate reported symptoms, check for white exhaust smoke, coolant loss, overheating patterns, and oil contamination to assess the likelihood of head gasket failure.
- 2
Diagnostic testing
We perform a block chemical test to detect combustion gases in the coolant, a compression test, and a cylinder leak-down test to pinpoint which cylinder and failure mode is involved.
- 3
Repair assessment
Based on diagnostic findings, we provide an honest assessment of whether head gasket repair is worthwhile given the vehicle's age and value, including the cost of machining the cylinder head.
When You Might Need Head Gasket Diagnosis
- White sweet-smelling smoke from the exhaust that does not go away after the engine warms up
- Coolant loss with no visible external leak, or milky oil on the dipstick or filler cap
- Engine overheating or air bubbles visible in the coolant overflow tank
