Updated Timing Chain Tensioner to Correct Noise on Startup on Kia Amanti

If the engine is excessively noisy on startup (after the engine has been off for several hours) and the noise lasts more than four or five seconds, turn off the engine and check for correct engine oil level. If the oil level is correct, the noise may be caused by the timing chain tensioner. Kia released an updated timing chain tensioner to solve this problem.

2005 Kia Amanti - 3.5L V6 80,000 mi,
My car sounds like a blender is running for about 10 to 15 minutes after running the car.
noisy worst in cold weather. kia told me it is a normal occurrence. but if I wanted it fixed it would approximately 1800.00 dollars. no mention about the timing chain. no warranty coverage.
2008 Kia Amanti - 3.5L V6 25,235 mi,
Every time I turn on the car it sounds like a lawn mower went off. Its terrible. Two years old and $33000 later I am fighting KIA to garentee the warranty. They say such noices is common, and not a transmission problem.
