Another Problem with my new '93 240

[Xneubien]

OK heres the problem. There is this annoying rattle right around 2000rpm and one right around 3000rpm. It sounds like a loose medal panel under the car. Its just bugging me when i have the windows down. Anyone had this problem before?

Could be a heat shield on the exhaust that has broken loose.

thanx for the tip...ill check it when i get it back...i had the same problem with my old integra...but the resonator had rusted out and rattled around.

Definitely check the heat shield on the exhaust. The Datsun used to rattle in a similar way all the time, at a specified RPM range.

Ditto the heat shield. Heres a tip, tighten it down, dont remove it. If you remove it, you will notice your right heel melting.

can u just remove the shields & use thermo wrap instead?

i noticed that the previous owner had remove them & during the warmer months, it does get kinda warm...

I'm thinking of wrapping it up; any negative side effects from doing that?

It could also be a timing chain bracket. Do a search for "timing chain retention bracket" or something similar. It seems almost everyone here has had that problem. It is an easy fix and makes a lot less noise.If there is a noise coming from the front of your valve cover, then that is probably it. If you can't find the fix, then email me, and I will tell you how to fix it.
