I have an annoying rattling problem at around 1000-1300 rpm. It can't be heard until I let the clutch all the way out. Its audible inside and outside the car when driving. Instead of throwing parts at it, I want to crawl under the car and try and listen for the noise. I'm not going to be spinning the engine more than 1500 rpm, so I don't think its going to hurt anything as long as its supported correctly by jackstands. I've just never heard of anyone doing this so just checking before I go ahead.

 

It is not a big deal to do, just be very careful and support the car properly. I did this to my car today.

 

yea, just dont spin the engine must faster than that, and please be very careful when putting the car on jackstands

 

And be especially cautious not to get anywhere near the driveshaft. If that thing grabs your jacket it can kill you to death.

 

I had a rattle under the car and it was the starter hitting the fly wheel. I used a stethoscope and it was very easy to be sure what it was. It cost $10 at the auto parts store. I made sure the car was very secure by pushing it in several different places before i got under.
