so i have had my 400 for about a week now
and of course it has new noises that it didnt a week ago.
(and its already been keyed, but thats neither here nor there...)

im getting a rattling sound coming from my engine compartment.
its hard to locate =\
after searching i think it may be an exhaust leak. the noise is there all of the time, but most present when i accelerate.

what are the most common exhaust leaks on stock sc400s?
from what i can tell, a lot of people have had problems with their cats. i dont have any check lights on. the noise doesnt sound low enough to the ground to be the cat. how likely are exhaust mani leaks on these cars?

thanks in advance

 

no idea about the exhaust situation, but i can totally relate with ur car being keyed. in fact, that gives me an idea for a thread...

 

yeah it just sucks that ive had it for a week... well, since sunday, so not even a week.
some people shouldnt live.

 

I actually have a similar situation with my 300. It sounds like it might be a sqeaky fan belt. go buy a bottle of belt lube/conditioner for three bucks and spray. If it is the belt go have it looked it and see if it needs to be re-tightened
