Hey everyone,

Got a 2019 Ranger here. The engine started ticking the other day and sounds like the in the attached video. Does anyone know what it is? The only other related threads I found were the fan clutch but my ticking seems to be too fast to be that. It's closer to the RPM of the engine. EVAP purge valve maybe?

It seems to only happen while the engine is idling or not under load. In neutral I can rev the engine, hear the ticking increase in frequency and then it disappears pretty quickly. At a stop, it ticks but then goes away as soon as I pull away.

Any ideas what it might be?

I would use a stethoscope to pinpoint the source of the noise.

It sounds like the Turbo By-Pass Valve but as already mentioned - stethoscope to confirm or a similar alternative tool (screwdriver handle)

By the metallic sound (echo) it may also be the AC Compressor Clutch or the Overdrive coupler on the Alternator
