It could be the lifters. Depending on the mileage and care as far as frequent oil changes one o rmor eof your lifters may be making a tickign sound. As the oil pressure builds up..........say after a minute or two does it go away? Try this....just turn the engien on and let it on and see if the ticking goes away when it warms up. If not, then it is probably not the lifters. The lifters are hydraulic and they maintain a certain oil pressure and as they get old they gum up from infrequent oil changes and they lose some of their ability to hold the pressure so they tick.
It takes few seconds for the fuel pump to kick in when attempting to start the car. If you try to turn the key to ignition position and before you crank it wait 1-2 seconds, you should be able to hear the fuel pump making a hissing noise, it should start right away.
if your talking about a v6 noise on start up. most all 3.1 make this noise until engine gets warm. if the noise does not go away when warmed up. better check it out !
I had the same problem it was just low on oil. ******************* It's usually lifter noise. It can be particularly nerve-wracking after the car has set for an extended period. As suggested, keeping your oil at the correct level will minimize it, but you might hear a little bit of lifter noise on every start.
Wheel bearings will cause a rumbling noise consistent with the revolution of the tires. Your highlander is doing a computerized check of systems. If your noise is like mine, when you start the engine and pull away you hear this noise and then it goes away.
after the car sits for a while ,the oil settles back down into the pan.On start up i takes a few seconds for the possible worn oil pump or partially clogged oil passages to pump oil to the upper end of the motor
A glazed belt can make that noise. Try rubbing a bar of soap on the belts and start it up. If the noise goes away temporarily, replace the belts.
Get a filter for your alternator. What you are hearing is alternator noise in the speakers. You can purchase these at a Radio shack or electronics store to take the alternator noise away.
i have a 2007 chevy cobalt.it only has 17000 miles on it. i had a remote car starter put in a year and ahalf ago. i never had a problem. now when i start my car it makes a clicking noise.the noise goes away after a few seconds and i can still drive the car.
I'd like to know too! Mine does the same thing - it makes a rattling noise upon startup that goes away after 30 seconds or so and isn't present while driving or idling.
If its coming from your engine, you may need a valve adjustment..
be cool! Start flirting(: look at them in the eye for 2 seconds then look away! it always works(:
All cars start and the revs are higher than at idle,butif there is a noise when starting that usually goes away, it could be a idle tensioner going bad or a faulty pulley/ bearing. Noise usually only last a few minutes.
