hello, new member here, i have been lurking for a few weeks and finally got a tundra 10 days ago( i love it).i have read the post on oil leaks and piston slap and dash rattle.i have none so far at 550 miles. i'm listing my circumstances and wondering can these problems be traced to one plant or climate zone. i do not wish to start "my truck is better than yours", but am interested.conditions: mine had 6mi on it off the truck{pre ordered}, not much below 40 degrees since i've had it and garage kept,built in indiana, dc 4x4 ltd , easy driver(i don't think it's been above 2300rpm yet).
