rattle noise

[sparker]

Still doesnt give me the detail I need... Can anyone circle a part from a picture of under a boxster to show me where I need to be checking for wear?

Thanks,
Sam

I had a rattle noise develop in the engine. Turns out it was the idler pulleys forthe belt. I took them off popped of the seal and greased them. They quieted down the engine a ton. It was really loud when the sound bounced off the garage wall. Its easy to check. Pull the interior engine cover off release the tension on the belt and spin them by hand. They should be silent.

thanks. maybe i'll try that. i put the back on some ramps again and banged around. definitely not the heat shield. but possibly the exhaust/cats. when i hit those, i do hear a slight rattle like a pepple stuck in them or something. but i couldn't isolate exactly where it was coming from. frustrating.

And the exhaust guy told me it was pebbles in between the shields and cat. I got under there and watched him whack it with the rubber mallet and it seemed to make sense. Am i nuts or is that possible?

probably not pebbles, but whacking it seems to be what a lot of other people end up doing ( if it's the heat shield ) because that will deform it and make it stop vibrating...

if it does sound like pebbles ( or what most people say - rocks rolling around in a tin can ) then that's often how the IMS bearing failure is described...
