#56 of 73 Piston slap is the "diesel" sound you hear when cold by Mojaveman Jan 24, 2009 (8:04 pm)
Replying to: jimmyg8 (Apr 14, 2008 3:37 pm) This is a widespread problem with the 5.7 (and 1st generation 4.7) engines and TMC is basically giving all the owners the middle finger salute because it will cost them many millions to fix. They have rushed a product to market before testing it fully and all of us unfortunate early buyers are paying the price in terms of long-term durability and resale value. It is particularly heinous in that Toyota will eventually reap the benefits of their bad engines by selling replacement parts in much greater quantities than they would otherwise. If we work together on this and spread the word it is much more likely that they will admit the problem and honor their contract with buyers. In the 1980s Honda introduced the Accura line of cars and when a snow storm hit back east it was found that some of their automatic transmissions would grenade if the car was rocked (due to poor engineering). Instead of ignoring the problem and telling owners to get screwed like TMC is doing to Tundra owners, they worked very quickly to identify the problem, come up with an engineering fix, begin building the new transmissions, inform customers and dealers (not to rock their cars until the transmission could be replaced) and systematically replaced all the transmission as quickly as possible at no small cost. I know because I was involved in the process. That is the kind of customer service that TMC should be offering to Tundra owners. Let's face it, TMC could do the right thing here or they can do what they are doing and ignore the problem hoping it will go away (or your warrantly will run out). I can guarantee you, I will never buy another Toyota if they continue to ignore the problem and I am going to work to ensure no one else does either. The only leverage we have is our wallet or potentially a class-action by a good law firm and then only the lawyers win as the settlement would probably amount to a $500 coupon for the purchase of a new truck and free oil changes for owners while the law firm makes $150M.

Replying to: beach_brada (Sep 02, 2007 7:24 pm) High RPM at startup is the least of your worries. Unless you are one of the few lucky 5.7 owners without piston slap you will notice that when you put a load on your engine that it sounds like an old Detroit Diesel with 300,000 miles on it. TMC refuses to fix the piston slap problem must owners are experiencing saying it is "normal." Piston slap is not normal and us owners that made the foolish decision to buy a truck that clearly wasn't tested properly are now going to pay the price in short engine life and poor trade-in value. Sooner or later some legal eagles are going to file a class-action against TMC over this issue. If you are reading this thread and contemplating the purchase of a new or used Tundra be advised the engines having major piston slap problems. Anyone that tells you that piston slap is normal doesn't know what they are talking about or works for TMC.

Replying to: Mojaveman (Jan 24, 2009 8:22 pm) I own a 2007 tundra .Bought April 2007 great truck. I had GM trucks all junk .They would not fix the crap even under warranty.The engine is the best on the market. makes a person think that you work or own one of the big 3 or a lawyer wanting a job. The big 3 have lost their market share.No matter what you say .People know better.I also bought a 2009 toyota avalon a nice car that gets 31 to 32 mpg.Alot nicer car then the big 3. I wish you the best on bashing toyota

Replying to: Mojaveman (Jan 24, 2009 8:22 pm) what do you say about the man talking pistons are like motorcycle pistons explaining possible noise? the slap will wear the piston out? i read the fords forum having some radiator problem burning out early #8 piston. what truck(s) do you recommend purchasing? what would you do to fix the slap issue? i am not mechanic but would like understand engineering fixes to this problem before purchasing toyota tundra. have you spoken to local engine enthusiasts/ seasoned veterans of tundra engines. Is this something motorcycles experience this issue will burn out piston overtime how many miles do you have on yours? how many more miles before you expect major ,,stop engine problems? no go toyota   maybe there is some arbitration available through toyota for your redemption? how are ongoing discussion with those who understand problem and are seeking answers to fix this issue?  similar victims, communicating other boards/forums tundratalk   how exactly was honda explanation resolved? i did see nicer 2002 chevy 2500hd man wanting $1500 above edmunds price parked on road,,looked in nice shape,maybe retain some american jobs/investment in the country while things go back to efficiency? customer value/response most important marketing moving forward giving back to investors>purchasers things can change with enough communications what about the 20/20 programs John Stossel interviewers

Replying to: Mojaveman (Jan 24, 2009 8:22 pm) is this problem existing on 2008s 2009s? is there fix in? do you have any survey of current engines?    those with newer acquistions? speaking to this issue,   what about other owners pulling loads?? is the survey 1 in 100 owners with similar problem 1 in 1000, 1 in 10,000   any other factors occuring same time pulling load,,major hills? flat ground? exxongas? 10% ethanol?
#61 of 73 2007 Toyota Tundra Piston Slap (TMC does not care) by standfirm5 Jan 30, 2009 (5:26 pm)
I left GM and Dodge trucks. So I went to Toyota thinking that they had higher standards and quality, but was i wrong. I bought a 2007 5.7 liter Tundra that has developed a piston slap like a diesel, this is not what I bought. I was told by Toyota that this was the GREATEST engine Toyota has ever made... well THEY DO NOT BACK UP WHAT THEY STAND FOR.. I have been to the dealer a half a dozen times about this, and called Toyota Corp.and had 2 Reps down from Chicago 3 times just to tell me this is the nature of the 5.7 top of the line high performance engine, and i just have to LIVE WITH IT. Thats BULL... they are not going to stand behind their product. ( BOTTOM LINE ). Now I have to listen to this all day long and what will happen when the miles rack up? or i go to sell it and resale is reflecting this issue? You pay over $37,000. you would think that it would run and sound the way it is suppose to be, especially for a Toyota? I'll NEVER BUY TOYOTA AGAIN, if they don't make this right. and i will TELL EVERYBODY, I PROMISE. DO NOT BUY TOYOTA TRUCKS... BUY AMERICAN.
#62 of 73 hard starting,will not always idle by luke21 Feb 18, 2009 (11:47 pm)
toyota tundra V6,003. engine cranks, but doesn't start right away.drove on highway,when I slowed down to get off highway the truck stalled, tried to re start, but would only start and keep running with my foot on the accelerator. continued to drive ,but when I came to a stop the engine would die.would only re start and drive with my foot on the accelerator. the next day it stated up ok,but engine idled a little rough. Is my fuel pump bad? Replies to this message: washu64 (Mar 02, 2009 2:39 pm) luke21 (Mar 05, 2009 11:51 pm)
#63 of 73 Re: Piston slap is the "diesel" sound you hear when cold [Mojaveman] by tymtotrn Feb 20, 2009 (9:16 pm)
Replying to: Mojaveman (Jan 24, 2009 8:04 pm) To All you gentlemen who are posting messages reference piston slap during cold start ups, and piston slap during low rpm acceleration.   1st--I spoke to a 20 year mechanic about engine oil type for my 08 5.7. I was told that these new high tech engines(especially Toyota) have very small and narrow passages in some parts of the motor, which make it difficult for oil to pass thru especially during cold start ups. That would explain the ping while cold. My 08 revs high during start up, but I do not hear a ping. I use a FULL synthetic oil..   2nd--As far as piston slap during low rpm acceleration, that sounds like a fuel octane problem. I dont care what anyone says(or any manual says), use 91 octane in your tundra. You must be running BAD fuel in your tundra. Use fuel from Chevron or Shell.   3rd--My last suggestion. Do to your tundra what I did to mine. ( Let me clarify that at no time have I ever experienced piston slap during start up or during low rpm acceleration). For several months, I researched a cold air intake system and a plug in computer chip for my tundra. Understand that these tundra's are equipped with stock air filter systems that ARE A JOKE. The engine can't even breath. No wonder it only gets 13mpg in the city and only has 381hp stock. I removed the stock air filter system and self installed an AFE cold air intake box in 1 hr. I already felt a noticeable difference in throttle response. And you know what MORE COLD AIR entering in the engine means--better gas mileage, more hp, and more torque. Then I put the icing on the cake by self installing a plug in UNICHIP computer chip to the tundra's ECU. Understand gentlemen, these 5.7 motors can generate tremendous horsepower and torque, but are tuned DOWN to meet safety standards. The tundra stock computer chip is programmed to allow the engine to generate only a small portion of its capable horsepower, torque, and gas mileage. (THEY GOTTA KEEP THE OIL COMPANYS HAPPY BY MAKING SURE YOU FILL UP YOUR TUNDRA'S FUEL TANK AS MUCH AS POSSIBLE). The UNICHIP I installed safely tells your stock tundra ECU to produce way more hp, torque, along with increased gas mileage. These 2 totally safe modifications to your tundra will cost you about 1100.00, will not void any factory warranty, are do it yourself projects, and will allow your tundra engine to effeciently breath and burn fuel. What does it all come down to?? At least 37-40 more HP, at least 35-40 more TORQUE, and a 2-3 MPG INCREASE. AND VERY POSSIBLY NO MORE ENGINE PING due to stock air intake system...
