You are in the Toyota Tundra Forum. Your Host is kcram
I have now owned my new '08 Tundra for 3 months now and have roughlt 4,200 miles on it. The truck is still running strong as the day I bought it. I've taking it on a few long distance trips and have towed around 8,000 lb.s with it. In trip to Loudon, NH on numbered routes the truck averaged 20.1 mpg. I couldn't believe it. For most commuting back and forth to work the truck has been averaging 18.4 mpg. I drive several side roads to get to the highway. The truck runs and drives great! The bed does bounce a tad over sharp bumps in the road but nothing severe. It's a pick-up truck after all.

| Hey guys I currently own a 2006 Dodge Ram 1500. It has about 55K miles and so far I've had no problems with the truck. My mileage is also somewhat decent. I am averaging 18 MPG all over. But I saw a Tundra a week ago and it was also very nice. It was a double-cab 5.7 l V8 2x4. I own a Dodge Ram quad-cab 5.7 l 2x4, and I was wondering what is new on the 2009 model Tundra's and what is the same from 2008. Also what would the value of my Dodge be. I have had no accidents in it and took pretty good care of it. Please reply back thank you. | |

Replying to: msalsbury (Oct 03, 2008 4:18 am) I have a 2008 Tundra w/ the 5.7 liter as well. I've done some research on the 5.7 engine knock. Toyota utilizes "short skirt" pistons. When the piston is on the power stroke (4 stroke engine) the short skirts causes the piston to rock back and forth (slightly) in the cylinders. When it is cold out side the knocking is loudly due to the metal of the pistons and cylinder walls being smaller. As the engine warms up the metal the gaps between the metal surfaces decreases. This helps quiet the knocking but not completely. My 5.7 knocks as well, if that makes you feel any better. Obviously, I have not heard how loudly your Tundra's engine is knocking. I can tell you that mine is quite loud when the abient temp. is 40 degrees or less. I have spoken to my local dealer and their responce matches what I have found out through Toyota Motor Corp. myself. Many manufactures use short skirt pistons in high performance engines. Motorcycle manufactures have used this technology for years without any failures. Honda, Yamaha, Suzuki and Kawasaki use this technology for lighter wieght pistons in their sport bikes to allow higher rpms for higher peak horsepower. I can only guess that Toyota has done the same with the 5.7 liter V8. (Toyota owns a good portion of Yamaha Motor Corp.) Yamaha builds some engines for Toyota.

| I just joined this forum,and have read a lot of interesting stuff on the 5.7iforce,I have a 07 tundra limited crew max 5.7 with 19971 miles on it an I couldn't be more pleased with it.The only time it goes to the shop is to have the oil changed every 5000 miles. | |
The noise that 75% of 5.7 liter engine owners hear for a few minutes after startup is piston slap plain and simple. It is impossible to say without testing and inspection what is causing the slap. It could be the cylinder(s) or piston(s) are out of tolerance. The piston or block could have a manufacturing defect. The piston or block could be poorly engineered. I am sure Toyota knows because the TMC regional rep admitted to me  they no longer build the engines like they did in 07 & 08. Typically, a loose piston (if not broken) causes excessive wear of the piston and cylinder wall resulting in increased blowby. This in turn exacerbates the problem further because the loose piston cannot transfer heat to the cylinder adequately. What you have is an engine that, providing something doesn't actually break, wears out much earlier than it should. In a State where smog inspections are done it much more likely that the vehicle will fail the emissions test long before it should have, not to mention degraded performance. Toyota no doubt takes the stand that as long as it lasts at least 100,000 miles, the length of the extended warranty, then who cares. One of the reasons we all bought a Toyota was the reputation of their products for durability which equates to resale value. That expectation no longer applies to the 07 & 08 trucks not only because something is wrong with them but because TMC has not the honor to fully admit the problem and fix it. I am exploring the potential for legal action as this problem is becoming widely recognized in many forums across the Internet and it is time for Tundra owners to get some satisfaction from the manufacturer with respect to repairs and warranty coverage of this issue. The owners of the 3.0 liter T-100s and Tacomas with cast iron blocks and aluminum heads that all had bad head gaskets were ignored until they resorted to legal action. Toyota finally replaced all the head gaskets but unfortunately trucks with those engines are now almost worthless because everyone knows you can't keep a head gasket in one. Is that the future of our 07 & 08 5.7 liter Tundras?

Replying to: kl67 (Apr 10, 2008 7:31 am) It take at least 15 mintues of driving to get the knock out . Sounds like a diesel Please if you could email me at : msportraits salsburystudio.com then I can discuss this with your dealer |
