Rattle when Idling

[stagger]

Wonder if anyone has had this problem.

When my R33 warms up it starts to make a rattle from somewhere near the drivers side wheel arch.

The sound comes when you give it a bit of stick and then back of or when you are sitting idling. Give it a small rev and it goes away until idling again. Anyone had this before.

Noise started after 1500 Km trip to Kalbarri on rough roads at high speed :flamed:

Does it sound like an engine rattle or more so from somewhere on the frame/body. Check bodykit mounting points, check indicators are still screwed in properly, check headlights. Rev it from the engine bay. You should be able to get an accurate location this way.

Hi,

I dont know too much but just thought this could be of help.

If the problem is not panels or bodykits, could be idler bearing... I had an exact problem with another car (not my skyline). So if your car has done close to 100K and the timing belt etc has not been changed, take this into account.

I had a chipped turbo wheel that rattled when idling.. But you could really hear where the noise was comming from.

Does it change / go-away when your clutch is engaged/disengaged?

Clutch doesn't change it, removed and re-seated headlights, checked struts and suspension, even tightened all the bolts and nuts in the vicinity, and relined the brakes. No loose panels and the body kit is all firm and intact. Just can't work out where the rattle is coming from.

From the inside of the car it sounds like it comes from near the wheelarch. From the engine bay can hardly hear it. Might be one of those pull everything apart on the long weekend jobs. :headspin:

Try this. Stand at the front of the car with the bonnet closed and see if you can hear it. Then open the bonnet and stand at the front of the car. Is the noise still as loud or does it change?.

With the bonnet closed - push down on the side of it to see if the noise changes note or volume. Try bouncing on the suspension to see if it changes.

Long shot but get your exhaust checked. Sometimes noises can be very deceptive as to their location. It is very likely that the noise could be on the opposite side of the car but it sounds like it's coming from the driver's side.

So is the noise definately louder from inside the car than out or is it just louder inside than out when the bonnet is up. (if you know what I mean ) ?
