Report: Varnish buildup in engine may cause ticking noise
Honda Passport Problem
Engine Affected: 3.2L V6
Average Mileage: 172,800 mi (115,000 mi - 215,000 mi)
Varnish build up in the engine can cause one or more hydraulic lash adjusters to stick and cause a ticking noise in the engine. The noisy hydraulic lifter will need to be located and cleaned to stop the noise.
