Hello there lads, Its been a few months since i boutgh the car, and have noticed a strange ticking metalic noise that is louder on cold, on a well warmed up engine you may be heard ticking but really quiet. The ticking sound itself is similar to a hydraulic lifter tick, or a loose timing chain/tensioner. When I changed engine oil 0w20, mechanic told me that it should not tick like that, he also said that hes not surr wheres the problem, he said it might be a bad lifter, and told me just to drive it since prius engine can tick like that for thousand of miles without breaking. i just wanted to ask where to dig, betwen lifter or timing chain tensioner? Maybe someone had similar issue?
welcome! did the ticking just start, or since you purchased it? is the mechanic well versed in prius? these engines are noisy, and worse when cold
