I just got my xB a week ago, I've only put about 500 miles on it so far. Today I noticed, for the first time, that the engine is kind of loud while idling. I dont really know how to describe it, but to me it almost sounds like a quiet diesel engine type of noise. Does this sound normal? Are these scion engines kinda noisy at idle? Thanks.

 

Mines a little noisy, compared to other 4 bangers, but not diesely. I just passed 10k and put amsoil 0w-20 in, which smoothed it out a bit. Was dealer 5w-30 before hand.

 

Like I said, Im not quite sure how to describe the noise, the diesel example wasnt the best probably.

I havent ever had a 4 banger, but at idle the engine makes more noise than the v-8 in my previous vehicle. It almost sounds like the injectors are just really loud or something.

 

If I get out and stand in front of mine, it's a bit loud compared to other cars. When my Sonata 2.4L is running, you can barely hear it. My xB is more quiet now, but Im running the 0w-20 syn and upper cylinder lubricant. This engine does click though.

 

Ok cool, im sure its probably normal then. I didnt even notice it until today and that was only because I walked right in front of it while it was idling.

 

Loud like this? Normal.

Yeah, a lot like that. Thanks.

 

No prob.

 

The 2az-fe is a loud engine, it does get annoying at times lol. Im use to smaller Honda 4 bangers that use a timing belt instead of a chain (which I believe plays a role in the loudness of our engines).

 

Thanks. I feel a lot better now lol.

 

Just a note, what's your idle RPM in and out of gear?

 

That chattering sound at cold start idle always makes me think it's going to blow up or something...

 

Im not entirely sure, Ill have to pay attention next time I drive. Its been kinda cold here this week and when I first start it in the mornings its been idling at just under 1k in park I believe. I am not sure what it idles at once it warms up or when its idling in drive though.
