I was standing at the rear of my car taking a leak today and I noticed as it idled, there was random popping like little mini backfires. They were very quiet.

Has anyone noticed this before? The car runs great, has 28,000 km.

Thanks.

 

This is normal for a rotary, dont worry.

 

Yeap....Its perfectly normal!! Isnt it freaking awesome...

 

i've never heard that. almost always in my car though when I have it on.

 

if i may take this opportunity to gain knowledge :
-what about rotary engines makes it normal to hear backfiring?

-what causes backfiring in piston engines and is it a sign that something is not operating properly?

thanks

 

Ya know when I hear my car do this some times I think: Did you just fart on me?

 

It's a little known fact that the rotary exhaust was pioneered by the Orville Redenbacher engineering group. they felt that the best way to keep emissions low was a thick layer of popcorn between the cat and the tail pipes. It's just doing it's job. No worries.

 

Am I the only one that finds it funny that a guy was taking a leak at the rear of his car and noticed this. That is hilarious

 

^HAHAHAHAHAHAH. yes such detail that we did not need.

 

I like the popping sound. I notice it even more since I put my Mazdaspeed Intake on.

 

I totally glossed over that part of the original post, as well.

 

Sonofabitch!!!

So did I.

 

lol ya i read that too but i do it often also we live on a big hill and if i dont feel like going in i just pee off the side of the hill

 

Maybe create another thread topic all together... "Popping sounds while peeing".....
hmm... maybe that doesn't sound so good.....

 

you shouldn't pee on your car. It pops when it's angry

 

Or floods lol
