The rattling is a worn-out timing chain (rattling should be louder at one end of the engine). Get it changed now - they will eventually break, closely followed by your bank balance!

Noise sounds like a metallic chirp from valve train.


To narrow it down, while the engine is running, don't get near moving parts, you can use a long piece of steel, metal, put 1 end on the valve cover, the other to your ear and listen for rattling. You can move it around to narrow down the source of the noise. It's like a stethoscope but works well. I use a 3' long screwdriver.

Jeep 360 rattle sound at idle in park


it could be a wrist pin, and im not sure if those amc's had hydraulic lifters but sometimes with old lifters when the oil pressure is lower at an idle the lifters arnt filling up all the way so they develope a little valve lash, and when the rpms are raised the oil pressure raises and fills the lifters. you could try chasing the noise down with an automotive stethoscope.

When I first start my truck I can hear a loud rattling sound coming from the back. Hear this sound also when I am in idle. Don't notice it when I pick up speed.


Check to see if one of your brackets holding the exhaust pipe has come loose. That'll make a rattling sound - especially if it towards the end by the tailpipe. When you're accelerating - more air is forced thru your exhaust at a faster rate, so it's not moving as much as when you're sitting still and the truck is just at an idle with less air/exhaust moving thru the tailpipe. If it's only making the noise while the truck is stationary & the noise stops one the truck is moving - that pretty much rules out anything to do withe the drive-train or suspension. You are sure the noise is from the back & not coming from under the hood? If under the hood - check your oil level ASAP.

Hi, my 99 Celica 1.8 has developed a very loud tick which appears to be coming from the inlet camshaft area. At idle speed it comes and goes like a noisy tappet but anything higher and it rattles loudly....


Your problem could be that your valves could be tapping and in need of adjustment if they can be adjusted.But since sound travels I would recommend you take it to your local mechanic to see if its possible for them to be adjusted.

I notice a rattle under the engine, sounds like exaust manifold? it goes away when I get up to speed-comes back at idle. Any idea?


Yup, on most vehicles there are heat shields attached to the major exhaust components. ie. silencers, cat convertors, mufflers. They are typically spot welded on and are above the unit.

They aslo tend to lose one or two connction points and vibrate and rattle really badly-- sounding much worse than the problem actually is.

In most cases it's perfectly safe to just yank them out.

I hear a rattling sound when I am traveling at over 40 mph on the highway. The sound seems to becoming from behind the driver side dashboard. I have looked under the dash and in the engine compartment but...


I had a similar problem on my 2007 RX350 and it was from the plastic gas tank protective cover under the SUV. There is a small portion of the cover that extends forward beside the gas tank, and usually has a rubber piece attached to it to stop it from hitting the floor under the car. The rubber had come of mine so I had to replace the rubber. This stopped it from hitting the bottom of the car at higher speeds. Worth taking a look at?

Oil consumption, rattle, engine noise


Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.
