Hi there,

the jumping, missing and rattling could be a result of poor timing.

Have you had the timing checked. If your timing belt or timing chain have some how jumped a slot or two on the cam gears then you may be trying to fire spark plugs at the wrong time and hence creat very poor running of the engine and sometimes due to valves being open at the wrong time it can result in back fires, or fuel ingniting through the intakes even.

Get the timing checked out - if you haven't changed the timing belt at an appropriate change it may be a deteriorating belt or a bad tensioner that is allowed the belt to slip.

If the timing is checked and the timing is good then you have bigger problems. Its possible the head gasket is leaking as per the previous entry, causing Light grey smoke to come out your exhaust. The coolant level would be going down though in that case and you need to check to see if the coolant level is reducing and also if there is a grey/brown sludge floating in your coolant fluid which would usually collect under the radiator cap.

If its blue smoke out your exhaust then it indicates oil being burnt and I would say you have some serious value issues, but for this to make the noise you mention it would have to be something like perhaps a bent valve or the 40000 miles you quoted is not accurate and you have a car that has been "Clocked" and has many more miles on it.

Regards

What colour is the motor oil ?? if it is gray (or grey) the motor is likely blown or you have blown a headgasket.

    I apologize.... it can also be a timing belt that should be replaced. best thing to do is not drive it till that is done as you may cause more damage to the motor.

Have a 2006 titan; noticed excess condensation and some white smoke after it was warm; also went I accelerate it sounds like a "metal rattle"(?) doesn't make that sound when at an idle...any suggestions?...


The condensation and white smoke could just be excess moisture that can build up in the muffler when the vehicles isn't used for a while or has been doing only short runs (less than 25-30 miles).. Keep an eye on the coolant level, and if it stays good then there isn't much to worry form that. As far as the "metal rattle" on acceleration, this could be what is known as "octane ping". It means that the engine is knocking a bit from fuel that isn't giving it enough octane. Cheap gas and occasional blending errors can cause this. Try running a tankful of mid-grade fuel next time. IF the noise goes away, you've found the culprit. Octane ping doesn't really hurt the engine, but it is annoying. You may be able to still use regular grade fuel, but might have to change the brand to find one that the truck likes better.

Occassional shrilling sound when I turn to park my car...back brakes were fixed less then 1 month ago...2nd time for the back brakes to be fixed....40,000 miles on car....the sound was not there before I...


Having the rear brakes done twice at 40,000 miles is ridiculous! something is definitly wrong. Could be a sticky park brake cable and may not necessarily be related to the noise you hear. The noise could also be a stone caught in the front brakes. Hope this helps!

2003 chevy impala makes clicking noise/smoking thru exhaust


the clicking noise could be eiter a valve or piston. the smoke out of the exhaust means different things depending on the color and how much smoke. Check your air filter and make sure oil is not backing up into it. Also, it may be a good ideal to go ahead and change the oil even though you arent at 3000 miles, unless you just changed it. Change the PCV valve also, if itis clogged it will give you problems. Has the check engine light come on?

I've a freelander td4 yr04 just had it a month and it's starting to judder some times shucking black smoke out when apply more power and theres a rattling noise


Faulty Injector or timing

If the injector is not spraying correctly you will be burning neat diesel out of the exhaust.

The effect of one cylinder missing will make the judder

If you bought it from a dealer take it back if you bought it off the street find a good fitter

Exhaust system rattling on 2005 300C. 58,000 miles!


You have a loose heat shield or a broken rubber mount.

jack your car up make sure you put some thing under need like a jack stand ( just for safety) and manually shake your muffler usually rattling noises are cause when metal rubes metal.
