Hey guys, Well I started my car today and this is the noise I heared. I have a '99 Z28 A4. The car has a larger cam/valve springs/pushrods ect...
anyways. I can't figure out wtf and i noticed that the noise is louder underneath the car then in above it... the oil pressure is normal at 40... what can I do to rule out some problems??
Thanks for your advice

no it's the loud ticking noise that gets louder as I move the camera to the ground.. the squeaking sound is a bad pulley

 

rod knock? or piston slap from a broken piston? hope its neiter!

 

Does it get louder and speed up with the RPM's? it sounds like its coming from the bottom end which doesn't sound good, i'd agree with maybe rod knock
ask me how i know

 

its hard to tell but i think im hearing a loud thump that is following the rpms of the motor? is there any way you can get a better quality video?

 

I will post a better quality video. Also i don't know if this helps or not...I drove it to the shop on friday to drop it off.. and after I drove about 5 miles the sound totally went away. I haven't heard from the shop yet. Sounds like they will not get a chance to look at it until Monday... The car seems to run perfect..... I don't understand what the hell happened. I went to start it up the other morning and it was instantly that noise... I doesn't get louder with rpms.....it stays the same volume...

Thanks for your help guys....I'm pretty sick right now about this The thing that sucks is I was going to sell my car for a good amount of money and put it down on a 2010 SS....

 

It sounds like a helicopter!! if you can get a better sound clip for now i agree with maybe a rod knock

 

is it stick or auto? sounds like a throwout bearing or a cracked flexplate.

 

that is an exhaust leak.....

 

ooo I hope it's an exhaust leak.....

 

oh and the car is an Auto... with only 69k miles on it.....

 

check your heads around where the manifolds bolt up and see if there is any black suet there. that is a good indication you have a blown gasket. also get under the car and see if you can pinpoint where the sound is coming from exactly. that will help lots as well.

 

ttt...

 

Well just a little follow up on the problem. Took the car into a local shop that I trust and they found I had a loose bolt on my torque converter. Problem solved!!!! I love cheap fixes!
