Possibly tappets need adjusting these are shims in buckets on top of valve springs on 4cyl vehicles and V6
need tools to do and shims on hand due to having to calculate shim needed from clearane measured and what thickness shim is all ready installed

My Lincoln Continental 2000 Model oil light came on engine stopped after 25 feet. would not restart even though oil full. The car started the next day, but had a rattling sound at the top of the motor

Oil light is rather important it goes out if oil pressure is good comes on if oil pressure is low when it comes on damage is expected with continued operation like wearing of main bearings and pistons and cylinders can lead to a engine rebuild

Driver side rattling noise disappears as speed up very loud when slow down coming from engine its a mini cooper 56 plate with only 31000 on the clock

It can be a number of issues if the noise is engine related but have the oil pressure checked with an external oil pressure gauge.
Most mechanics will have them.
I would also change the oil and oil filter immediately and ensure you ONLY use the correct oil as specified by the manufacturer for that engine. (Using an incorrect formulation or the wrong grade will cause engine issues).

I suspect the engine is losing oil pressure and oil flow at low RPM and you are getting metal to metal contact on the top end of the engine when this happens as the low pressure is producing a lack lubrication to the upper end of the engine. At higher RPM the oil pressure increases as does the oil flow and the noisy internals are getting sufficient lubrication again or at least enough to eliminate metal to metal contact and stop the rattling.

What is the cause of rattling noise in the engine compartment? Nothing shows on the dashboard.

Maybe a Tool that was left in the Engine Compartment? A Heat Shield that has come loose?

What were you doing JUST BEFORE the noise started? Did someone work on the car? Have you checked the Oil Level?

Rattling/clinging when car is cold. Stops soon after.

not the water pump as the noise will remain constant hot or cold
you leave very important details like make . model , year and engine type petrol or diesel so answering becomes a hit and miss affair
if the engine has a timing chain it indicates that the hydraulic adjuster is loose until oil pressure is built up which equates to a badly worn chain
next if an incorrect oil filter was used , the oil will drain back over night and , chains, rockers, hydraulic lifters will all rattle until pressure is built up
incorrect oil viscosity will drain down quickly and will take time to build up pressure as well
you may have to find an accredited service shop and leave it there over night so that the diagnosis can be made in the same conditions for them as for you and then get a quote

What would cause 99 alero 4 cyl. to make a rattleing sound when idle.. but not when its running at a high rpm.. sounds like its coming from the passenger side of the motor, sounds like something is...

noises are tough, but try getting under the car when the engine is cold and it has been sitting for a while and hit (with your fist) the catalytic converter-the substrate in cats break up and cause rattles that are especially noticable when the vehicle is running at low speeds.

Engine rattle noise

Have you checked your oil? Sounds like you may have run it way low, the loud metallic noise is probably metal on metal contact inside your engine, add oil and it that fixes it, count yourself lucky, if not need to take it to a shop.

I have a 2001 Ford ranger supercab that makes rattling noises. It has a 4.0L SOHC. It makes a very fast and loud metallic rattle wich softens anfter about a second or so when I first start it for the day....

4.0l's are notorious for valve rattle on cold start-up. There is really nothing you can do to make it go away short of completely replacing the valve train in the top end, and that isn't a permanent fix. It's is an top end oiling issue from the factory. Just don't race your engine on cold start-up until the rattle stops.

The rattle in the transmission sounds to me to be more of a loose dust shield/heat shield around the transmission or exhaust than a mechanical issue.

2002 cavalier engine noise

Hello there Its a Known problem with these engines..The lifters are usually the case to thes problem or the rocker arms are coming loose.Take off valve cover and start to find the bad one..Oil will leak over head but is the only way to pin point the problem.If the sound is a little lower in the motor It might have a sloppy rist pin in the cylinder causing the piston to slap the side walls..If it does it at an idle or under a load its the rist pin.If it does it at all different rpm and doesnt matter if its under load its the lifter area.Now the timing chain.Could case all thee above.So a way to check that is as long as you got the belt off grab a hold off the crank pulley and rock it back and forth.If you feel it grab a few inches side to side iits really loose and thats your problem.If it doesnt have much slop back and forth and turns the cam quickly the move on to the other parts I have stated.These steps will help you to solve the problem.I hope this helps you and good luck..Have a great after noon...

Rattling Coming from Engine At low RPM (stopped) and when accl.

If this sounds like a tin can rattle it is likely a loose heat shield on top of the catalytic converter. They come loose after time and corrosion take their toll.
