At cold start-up, a Honda engine rattles loudly for about two seconds. What could the possible cause be?
Andrew Markel helps diagnose a customer complaint of a rattle or clunk from the engine when the vehicle is started in the morning, and how oil pressure could affect the variable valve timing system. Sponsored by Auto Value and Bumper to Bumper.
As engine technology has evolved and fuel efficiency standards have tightened, oil specs have increased in importance. Using the wrong viscosity could set a fault code in some applications or interfere with the normal operation of the variable valve timing system. VVT engines not only require a specific oil viscosity, but also require an oil that keeps the pulse-modulated variable valve timing solenoids clean, lubricated and free of small air bubbles.
