I want to say it's been there since I've had the car (which isn't long)...I've changed the IMSB ~500 mi ago to be safe, it's very quiet and you can't hear it with the doors open when applying throttle. Put my phone underneath the exhaust, mic facing up. The video definitely makes it seem a bit louder than it really is.

 

I'm as paranoid as any non-KK Rennlister, but I don't hear anything bad there. But I have pretty bad hearing in general.

 

Do you not hear the rattle, or is the rattle normal?

 

I hear what sounds like the serpentine belt and perhaps a slightly noisy pulley in there somewhere -- nothing significant from that recording.

 

Yeah, sounds like a normal engine to me.

 

Just wanted to be sure. Thanks!

 

My engine doesn't sound like that.

 

i'm hearing a constant ticking noise - i'd ask someone like jake raby

 

defo tickaticka sound going on there. The same as mine but mine goes after 2 seconds. I don't know anything about the inside of an engine but I believed that sound to be either a chain slap or lifter sound. What ever the hell those are lol.

 

Yeah that's exactly what's concerning me.

 

While on the starter, I hear a cylinder with low compression. The sound is classic, too.

 

Uh oh.

 

Define classic? I'd assume compression wouldn't be perfect, the car's got over 100k on the clock. It's bound to have lost some horses. I'm not really sure how you'd be able to tell that from the starter though.

 

Nobody has an idea? The sound seems like its coming from well behind the rear wheels; doesn't sound like it's coming from where the isolated imsb is.

 

sounds like my motor did before I rebuilt it. don't like that tapping noise.
