Do you live in a climate where the temp.s stay below freezing from longer periods of time? When it is cold (er) ambient temperature outside the metals are "shrunk". Until the engine is up to normal operating temperature (180 degrees F) the pistons are "small" due to the metal confirguration (alloys used) as compared to the cylinder walls and sleeves. I had a 1987 4Runner with the bullet proof 22RE 4cyl. engine. That particular year had short piston skirts in it also. It would knock a little prior to engine warm up on colder days. I had a freeze plug rust out on the side of the engine block back in 2002 w/ the odometer showing 167k on it. I torn the engine down and there was no excessive wear on either the cylinder walls or piston skirts. I decided to check it out by removing the head and inspecting the everything internally while the engine is down for the freeze plugs to be replaced. Everything was well within spec.s and the rig ran great till it met it's final match against a moose. The moose won. The engine still ran great after the collision with the aforemention creature however the body panels looked like tin foil. Toyota manufactures everything the same and have very good quality control. They can tell very quickly when something is not right and have proceedures and measure in place the correct the problem quickly within the manufacturing process. That is why I do not believe their are a "batch" of unexplained extremely bad knocking 5.7 liters out there. That's not to say that Toyota is perfect and if somthing were to be manufactured incorrectly that it couldn't reach the consumer. There has been too many people in my humble opinion clammering about this non-existance "issue". If my 5.7 blows up then I'll have to eat humble pie. And I will be more than happy to report such a problem on this forum. Until then I will not believe that someone sitting behind a keyboard and monitor that can not prove they actually own a Tundra type possibly misleading things about the truck. Remember anybody with internet access can write what ever they'd like whether it be truthful or not. I have researched it because I do own a Tundra with the 5.7 liter and my knocks from time to time when it's cold. I have spoken with my local dealer, Regional Toyota Rep., friends or mine who own the exact same truck. They all say the same thing and I am very familar with engines built like the Tundra's 5.7 liter V8 due to my racing experience...in a former life.

I live in the southern portion of Georgia[31642] and for the most part we have mild winters down here.But on some occasion the temp.will drop into the teens,but once again when I crank her up the temp inside the truck will show 17 to 18 degrees,with no piston noise,only the high idle that I've learned to live with.

My tundra makes the same piston slap noise...not comforting for a new truck
Neither was the 4wd unit going out, while needed, in the snow.
Now there's an engine noise. This truck is junkier than the dodge I had! Who built this POS?

Salsbury,
Perhaps if you are truly that disgusted with your truck you should go back to a Dodge product?
My 4WD unit decided to get itself stuck in 4WD Hi not too long ago. Toyota has since issued a "TSB" or Technical Service Bulletin that updates the actuators for the 4WD system as well as a newer 4WD ECU. I am sorry you feel as though your Tundra is a POS. As to who built your truck...Americans in an American plant not a Mexican south of the border as you will find with a Dodge product.
I realize you are not happy with the truck you purchased and given the amount of money new vehicles cost I can feel you pain. However I am unsure of what expectations you preceive to have. Nothing in this world is perfect. I have answered your noise question with all the knowledge I have acquired through the proper channels. It sounds as if you have two choices...live with the noise or buy purchase another make or model. Good luck.

mine (07 5.7l 2 door tundra grade with sr5 badging)was built in san antonio but i doubt it has to do with where it was built. there are two things on mine that work flawlessly and easily(big !point on easily) the cruise control and the tail gate lowering mechanism. i have the slap sometimes more than others during warmup but after 10/12 miles it does subside. the transmission is from hell just last night after a quick deceleration i got back on the gas to make the turn and nothing then a big clunk like i had been rear ended. From reflections off the the bend in the hood, dash board plastic, and toyota emblem on the steering wheel to the placement of the wiper control it appears toyota has never built a truck/car before and i have had three toyota trucks this being the 4th and a royal lemon and since they did not cover the door stop complete breakage at 13400 under warranty and the first problem was within a year and under 12000 i am pursuing a lemon law suit. Btw i got out of a dodge 03 3/4 ton with over 100k on the v10, ran like a john deer, with some minor pains in neck

I think you're right about the piston slap--I've heard a number of other tundras in colder weather make the same noise on start-up, until about fully warm. It's a bit unsettling, but Ok.
xfer case actuator issue is a whole other can of worms. I'm not how toyota designed this xfer case (2spd on 6 sp AT/5.7) but it is not only fickle, but slow to respond and engage, it seems like aroll of the dice with the xfer case at times.
I've now had mine replaced (at 3K miles). Works OK, but still clunky. Disappointing anyway, from a toyota. Transmission now whines, as if there is something not lined up properly...probably because something isn't! It's been in the shop for more than a month out of the past six months--not what I expected from a new toyota truck.

As far as expectations.....
1. Toyota should at least acknolage the problem and replace or fix the engines that are knocking. I went to the dealer and started a NEW truck and they do not knock at all . Even my neigbours tundra does not knock.
2. Well yes , I could sell my truck but then who in their right mind would give me a proper market price with an engine that knocks . Maybe Toyota should do a buy back and try to sell their knocking trucks themselves and see how much fun they have trying to sell all the knocking tundra.
So all in all Toyota has left the customer holding the bag with a knocking truck that will be very hard for the owner to getgood resell value on. As started on other posts Toyota's 2009 tundra engines are built different and they do not have those proboems. Hmmm maybe Toyota should be replacing the 07's with the new improved 09's engines there is an idea !!

You say " 5.7 liter V8 is due to the use of short piston skirts." You sound like a dealer .Are you a Toyota rep yourself ?
You say "You will hear the same exact "piston slap" on a new Nissan or Dodge for that matter " My cousin repairs Nissans at a Nissan dealer and they do not have piston slap. My wife owns a aluminum short shirt Nissan engine and NO it does not knock no matter how hard I try and listen.

There seems like there is no way to please you. I have tried to explain the "problem" or "issue" as best I can. Yet you still feel the need to be negative. Perhaps you're a Dodge dealer spreading negativity on the web to push your product? How is anyone to know who YOU are? Just because one engine is louder than another with it's noises doesn't make it a lemon. Good luck with your arbitration suit. I truly hope you "win" so you'll feel no need to complain on this forum anymore. If I was a Toyota representative do you think I would admit my personal Tundra's transfer case got stuck in 4WD? And why do you post the same message on this site more than once? Reading your comments once is enough for anybody to take. And it's "resale" value not "resell". If I have made you feel as though I have defended Toyota Motor Corp. too much then I am truly sorry. If you look at the industry as a whole you will find the Big 3 have many more problems with their vehicles than Toyota. Given the odds of that I'll stick with my choice in buying my Tundra rather than spending my hard earn cash on a full sized p/u from the Big 3 that I KNOW won't be worth anything in 3 years. Good bye and good luck to you. If your suit goes through and if you win I do wish you nothing but the best with what ever product you choose to purchase to replace your Tundra. I'll just be glad that you can complain about it on a different forum.

Got 39K and counting, had one head-light lamp go bad, but that was when truck ran over a large gator (tire tread chunk off a Semi-trucks), replaced a dirty air-filter (prolly had to do with dust/dirt construction sites), and kept to routine oil-changes.
Could this truck use a 7 or 8 speed tranny, and go for even better mileage? I get about 18.5 mixed use (no-load), and about 16.5 on some load, and about 12.5 on heavy trailer-pull.
Personally prefer a Garmin (a portable GPS) over factory navigation system, for better carrying possibility, and update/upgrade ease.
Whats wrong with those squeaky OEM Dunlop tires, may be good for MPG, but may not be ideal for good grip/traction. What tires do you suggest for on-road comfort and minor construction-site (dirt/unpaved) use?
Is 2010 model doing any better - mpg, features and/or price ?
