Maybe my use of the word "Dreaded" was a bit much, but I surely didnt expect in 2008 that a gasoline engine make this much noise, and by noise I mean, clicking, clacking,rattling.
Someone in an earlier post said that its because of Quad cams, 4 valves per Cylinder,timing chains. I understand all of that, but like I also stated, my Cobra with the 4.6 DOHC 4 valves per cylinder, forged internals,timing chains, big injectors, supercharged Car NEVER made any such Noise with either the stock engine or this Built engine. Heck my wife's 2006 4.7 Sequoia engine is so quiet you cant even tell its running.
This thread was not to dis Toyota's or that the 5.7 engine is a "bad" designed engine, I was just wanting to get some real world feedback from owners who have had the truck for some time and "if" their ticking noise ever became a major issue with failure.

Honestly, I don't this anybody has the foggiest idea what anybody else is talking about. The "dreaded" sound is described in many different ways... is it ticking, clunking, knocking, tapping, etc?
At idle, my Tundra is still quieter than my Subaru. It's just a loud engine due to its design geometry. It's been a great car for me, and I'm sure it will continue to be so.
The injectors are big and loud, the pistons are forged, the stainless steel tubular headers are loud, yada yada... it's pretty much all been said already. Is the sound of the cold idling engine really abnormal? I vote no.
This isn't the first engine Toyota has ever built. At the very least, it's the second... maybe third. 
Anyways, until there is some evidence to the contrary, I am going to continue about my normal life and enjoy my dieseling sound  |
