Replying to: bearcrkrd (Jun 28, 2007 10:55 am) So have used 1.2 quarts in 1,500 miles. I have no idea why usage has slowed, am guessing it is warmer overnight, so engine has to work less when cold? I don't think there is too much of a warm-up period before hitting the road, or at least taking it easy for 2-3 minutes or so. Bringing it up and trying to explain just gets percieved as looking down on someone, so umm.... TMI, sorry.

Replying to: hoodlatch (Jun 27, 2007 4:48 pm) 1,575 miles, including a just-completed Interstate & Hwy trip across WA and back in fairly warm temps. Used just slightly less than one quart. Like a tenth less, but it is less, and an improvement! |

I have a 4 cylinder 03 Camry. I can hear the engine noise under light acceleration (about 2000 rpm). I had driven my friend's 94 Camry 4 cylinder with 150000 mi on it, and the engine is quieter than my Camry with only 32000 mi. Is the quality declined or what. I want to hear other Camry owners' opinions about this. Is this just a single case or it is a commom problem amone all 4 cylinder Camry (02~06) Thank You for any Suggestions and Opinions

Replying to: mike215 (Sep 23, 2007 5:11 pm) Does it hum at the speed of the engine? So when you speed up the engine, the humming gets louder/faster? If it does, you can take off the accessory belt for a short period of time, which will determine whether the sound is from 'inside' the engine, or outside on one of the accessories. |

Replying to: kiawah (Sep 23, 2007 5:45 pm) The other time I hear a similar noise is when I am on the highway accelerating gradually in high gear at low rpms - say between 2,000 rpm and 2,300 rpm or lower. Once I get above 2,400 rpm (about 70 mph) the noise goes away. This humming is similar in pitch to that of the noise I hear when the engine is idleing, but the pitch rises with the rpm's. Finally, the other time I hear the humming is at low speeds after I take my foot off the accelerator and I am coasting. At this time, the humming sounds exactly the same as when the car is idleing. Thanks for replying to my message. I hope you can give me some insight into where this noise could be coming from. |

Take off the accessories serpentine belt - find the belt tensioner and there is usually a wrench attachment point where you put a large wrench on it and take the pressure off of the belt. Remove the belt from the pulley and slowly let loose of the tensioner as if it were going to put pressure back on the belt (but it's not there). Get the belt out of the way from the crankshaft pulley, so you can start the engine and not get anything caught. When you start the engine, you will find that either the weird sound continues, or it's stopped. If it is still humming, then the source is either inside the engine, or it is something electrical which is still powered. Usually I find the noise has stopped, which you then know is one of the belt driven accessories or pulley's causing the problem. Turn the engine off (and you don't want to leave it running a long time anyhow as you don't want it to overheat). Now turn each of the pulley accessories by hand, and listen feel for whether they turn smoothly, or bind or make noise. When you find the noisy pulley, you know exactly what to fix. To put the belt back on, line up the belt back onto all the pulleys but the tensioner, apply the wrench to put pressure on the tensioner (allowing the belt to go back into place), slip the belt back on the pulley, and you're done. This whole procedure is very easy to do, and doesn't take much time. It wouldn't surprise me if you had a bad pulley on the tensioner itself. |
