Weird sound on startup

[CO2Ranger]

So when I start my truck after it's been sitting a while it makes a concerning noise that resembles a bullfrog but with the pitch of a cricket. Almost like someone cranking on a ratchet. Does it 2-3 times, spaced out, then it's fine.

Any ideas? I'll try to get some video but it sounds like the passenger side of the engine bay.

Ah, Wastegate actuator arm squeak. Freaked me out the first time I heard it. I think either it has stopped making the sound now, or I'm just used to it and no longer notice it.

6500 miles on my ranger and still makes it service said there is no issue they all make that noise

Thanks all, that other thread is my bullfrog cricket exactly. Lol. Didn't see that when I searched. I can live with it now that I know what it is.

Hi Folks,

You might try this Extreme High Temp Lube that I use on my RV CAT Engine Turbo's exhaust brake (not a Jake Brake!).
