I have an 05 Corolla S with 95K on her. Need some of you Guru's advice. I ocassionally get that start up rattle noise after setting over night. Its worse when it gets cold and I don't know if its a coincidence or not but it seems more pronounced right after a oil change and filter. Things I've done. Pennzoil 5W-30 5 K Oil change. Doesn't matter if Toyota OEM or Wix filter. Belt changed. I'm thinking belt tensioner but don't want to throw away $150.00. Please tell me if Belt Tensioner solved your problem. The toyota dealer in my town is Incompetent because I took my car in twice while under warranty and they heard noise but could not find out why it was doing it. Now I find out there is a TSB out in 2007 that would of Paid for this repair. I Trust You Guys More Than Mother Toyota Or The Incompetent BooBs that call their establishment a "dealership"
The belt tensioner caused it for me but I would definitely not recommend replacing it just based on that. The tensioner might have plenty of miles left in it before it finally goes. When mine started bouncing around while idling, that's when I knew to replace it. The rattle definitely sounds bad, but once it's running, as long as it isn't making noise, I say, don't worry. If you can get a new tensioner out of them, more power to you.

I tend to agree its the tentioner and not a internal lubrication problem. This spring I will buy the Dayco kit and replace it. My car should have 100K on it and I would not mind spending the money.
Mine only makes a rattle noise when it is very cold outside and when the car is cold. Once it warms up it stops. I will make a loud rattle on a cold startup and rattle a little during idle, when accelerating the rattle gets loud. It took me a while to figure out what it was. On mine it is the exhaust pipe vibrating against the strap that runs across the pipe by the resonator.

UPDATE! Changed VVTi filter.It was not that dirty after 96K miles. Didn't make a diffrence. Changed belt tentioner and the rattling is gone but I still get this ticking noise like the valve train is noisey upon acceleration only not on decel. Any suggestions?Also car seems to run rougher. Idon't have a MIL code.

Noise like you describe - under load and worse when cold sounds like piston slap. Alot of these 1ZZ engines seem to make this noise when they get 100k+ miles on them. My brother and I both have Pontiac Vibes(1ZZ engine) that make this noise.

If it was the valves the noise should be the same under decel and accel, correct? Since the OP said the noise is under accel only it cannot be the valves? Please correct me if I am wrong, I have the same noise.
Load based noise is probably pinging from low octane fuel, dirty injectors, or carbon build-up.
Or piston slap - you live in Florida and don't experience the 1zz in cold temperatures. My 1zz slaps starts slapping progressively worse under 40° until warmed up - summer or warmer temps there is no noise.
The OP lives in a colder climate.
The piston slap happens mostly on cold start and is common on many engines including the illustrious 2GRFE V6.
These engines are noisy because the timing chains and low insulation.
Check the valve adjustment and see if some are a little loose causing a rattle.
Valve noise/ticking is doing it both when engine is hot or cold. when in park I rev engine up to 2K to 3K and don't hear it. In drive and I hit the accelerator I hear the ticking. It is linear to how I press the gas petal. When I let off gas petal its not there. Its not detonation cause I know what that sounds like marbles in a can. This afternoon I took top cover off and put my ear to the valve train. This engine makes so much noise its startling. Remember how smooth and quiet our engines were when we test drove our corolla's at the dealership before buying? Btw one of the noises are coming from the VSV does it rattle more upon acceleration? Also I don't want to do a valve adjustment for 600.00 and it don't solve the problem. When I call my enept Toyota dealership they state thev'e never done a valve adjustment and to save my money. Anways Thanks guys for your suggestion I'll just drive it untill it blows up then get me a Honda like I should of in the first place.

Detonation is different than pinging under load.
What gas you use? Have you ever cleaned the injectors? Have you ever done a carbon removing throttle service? Have you ever done the intake gasket?
Any technician with half a worth can easily do a valve adjustment for significantly less than $600.00.
The VSV does make noise but the racket is likely mostly coming from the timing chain and associated parts which are noisy (the main reason luxury cars with chains don't sound noisy is because of heavy insulation).
Hondas are known especially for noisy valve trains and need valve adjustments periodically as well. And remember 8th Gen and newer Civic and all KA engines use chains and noisy operation will eventually come.

Changed intake gasket, changed vvti screen changed belt and tensioner. I do have the normal seepage of oil at the timing chain tentioner. I have another Toyota dealer about 40 miles away may make an appointment with them and see what they think. I will keep all informed what I find since so many of us is having the same problem. I don't use any oil between 5 k oil changes so I doubt its hurting the motor. I forgot to mention we have 3 corolla's in the family and mine is the one who's ticking is the loudest. the other ones are a 2003 and another 2005 LE with 89K and 60 K.
