Anybody else have this 1 second rattle on cold startup. Sounds like cam waiting for oil. Like when you first start a motor after oil change and the filter has no oil in it yet. Seams to be a pretty widespread problem on the 2arfe motor. I've been browsing around and a lot of people say it's some vvt-i lock pin problem while others say it's just the hydraulics lifters before they build up pressure. If everyone else has the same problem I'm not going to bother going to the dealer. I suppose if it's the lifters before they build pressure it's not really a problem, but just the nature of hydraulic lifters. Thanks guys !

These motors have a very distinct sound to them, almost sounds like a knock to me, but I've never heard a rattle on starting

Ya I think i should be able to get the dealer to fix it. I found tsb for camry and rav4. I finally just found the exact same tsb for the scion tc published in 2013. Something along the lines of replacing cam gears.

Had this noise since day 1 and so did my moms Rav4, no issues yet.

Good to know if the dealership screws me. Don't see how they could reject me when i have the tsb number tho. How many miles you have russiankid. Or the rav4 for that matter. A high mileage motor with the issue would settle me down a bit. Pretty wound up. Been doing it since i picked it up brand new. Now has 2600km on it. In 3 weeks lol. No issues other than that annoying cold start rattle. Sounds so harsh on the motor. Prob cuz it sounds like cam to me even tho its not.

Could you post up the info to the TSB? I am at 40k and haven't had any issues/not something that is uncommon to me.

All i got is the tsb number and what it is "S-SB -0010-13 Brief engine knock/rattle noise at cold startup". The website I found it on wants money to see the details. But if you google camry startup noise tsb it's the same thing. Replaces cam gears and something to do with the vvt-i system as there is a pin that's supposed to lock into the cam gear at startup to make for smoother/quicker starts or something like that. It doesn't lock in and rattles until oil pressure gets to it. Not word for word but that's the just of it. Here is a clip of the sound from someone else. http://m.youtube.com/watch?v=Kn4TFKggiKI

Video won't load for me, but either way I don't see how cam gears would be at fault.

HOODedDutchman

I dunno that's what the tsb says. It's because at shutdown the vvt-i locks a pin into the cam gear to change timing for easier startup or something. So pin doesn't go in properly then rattles at startup until oil gets to it. If you've never had issues with high mileage I'm not worried about it I guess. Here is another video of it in a rav4.http://m.youtube.com/watch?v=ZK3jEwMZoRc

Ps might be because of mobile version that your not loading. Sorry I'm on my phone.

Same noise I have but I don't think mine is that loud, not to mention I don't really hear it anymore with the exhaust. I don't think this noise will cause any damage so having another nut job at a dealer tear into the valve train is unneeded. I've had enough bad experiences with dealers and my transmission, don't want to deal with the engine now.

CBechdolt

Wow that sounds terrible, but like Russian said I wouldn't want to go let a dealer take it apart either, id just wait and if it blows up get a new engine lol

HOODedDutchman

Ya mine doesn't seam to be that loud either. More like the first video. The 2nd rav4 video is much louder. I've seen some people saying it could just be hydraulic lifters before they build oil pressure or something. O well if it gets worse I'll just go rage on them until they fix it. Otherwise screw it. I've heard toyota uses synthetic from the factory with a break in additive, may be the cause of this too. Your always suppose to break in a motor for 5-10,000km on conventional oil then move to synthetic. I may have been misinformed about this tho.

mine did it this morning. not loud like the rav 4 vid

russiankid

I changed my oil at 800 miles, then used regular oil till 5k miles.

ranger024x4

the dealer told me that the tc's come with synthetic from factory, and no additive is used. I plan on changing mine at 500 miles to mobile 1

HOODedDutchman

Dealer probably doesn't know anything about additives. There is a thread around here saying you are supposed to go 10,000 miles before changing oil because of the additive.

This topic has been beaten to death.

Noise is from your intake cam gear(vvt-i gear). Common problem on the 2AR-FE engine.

The additive is most likely a safety measure because the general public doesn't understand that things need to wear into each other before you go beating around on the car. If you have half a brain, you'll understand this simple principle and everything will be fine. A lot of engines that are rebuilt/built don't use any special oils for break in.

when the lady took the car this morning I heard the rattle for a bit :/ terrible.! 2014
