One problem after another!

[zoe the z]

Yesterday i took my friend allan out for alitle ride to listen to this noise my car is making, the question is about the noise...but i also have alittle story for you. Well anyway i'll start with the noise, it's a clinking noise that happens in 2nd gear around 3000 rpms and in 3rd gear around 3000 rpms it sounds like metal hitting metal, not hard but hard enough to make a noise i talked to one guy on zcar.com and he said he had a problem that sounds like mine and it was his exhaust liner and he had to take apart the exhaust manifold...anybody else ever had a problem like this??....oh and anyway back to the rest of the story i took him for a ride to foothill highschool about a half a mile away and park in an open parking lot and skate for about an hour order pizza from where i work at and eat and skate for another half hour or so...then we notice two mexican guys(and if you are mexican dont get mad im sorry, i myself am half mexican) but these mexican guy are pretty thugged out and they have a garbage bag, at the time i thought nothing about it...so anyway we walk back to my car and i notice the plywood i fit perfectly in my z for my 6x9's is moved around and the 6x9's arent there anymore at first i thought maybe it was a joke...then i realized they were stolen along with my cd deck...i thought it would be okay in a open parking lot in broad daylight but i guess not and it makes me feel really dirty that someone can just open what i own and take what i worked for...but i tried to look at the bright side and the only thing i could think of was maybe the guys who stole it have children and hopefully my deck and speakers will buy kids food or something like that...i hope he doesnt sell it and spend it on drugs...well thats my story anyway anybody with any thoughts or opinions on my clinking noise everything you have to say is welcome here.

What kind of car do you have? Year? Model? 240Z exhaust manifolds don't have liners.

Have you looked under the car at the tail pipe ? I could be a loose clamp that is vibrating from viberation at 3K. Or does the sound seem to be related to the speed of the car and become less frequent as you slow down , or increase if you speed up ? If you are parked and you slowly increase the RPM to 3k do you hear the sound then? Gary

its a 1976 280z...and i can hear it towards that fromt of the car so i dont think its a loose tail pipe ummm it happens with me driving slow and fast around 3000 in 2nd and 3rd gear

hey, that was me that told you about the liner...

yeah... it sucked balls... no matter what gear, from 1700 to 3k... all of the time, no matter what speed or gear.

i was adding a header anyways, so i just solved it then... but now the #4 cyl. is flowing just a l i t t l e more than the rest...

Sorry to hear about your speakers but at least you will never make the same mistake again and lock your car from now on regardless.

Does the car also have extra vibration to it when it happens?

Check under your car do the bushes in your suspension look stuffed?
