Question about 2008 Toyota Sienna
I can only assume that you are having the oil changed at a local "lube shop". $19.99 oil changes?! There is a difference in the quality of oil filters used. Make sure that they are using the correct oil wieght which will be in your owner's handbook. Also use a Toyota oil filter. You will notice a difference and the oil pressure will be held during a cold start so that the valve lifters properly oiled and pressurized. Have the oil changed at the dealer or at least with the dealer filter and see if it improves. Let me know.

This is an engine oil lubrication concern.Your oil that you have during first initial startup does not have enough viscosity in it. (not thick enough) .The quickest and easiest fix to this problem is to go get an oil change with a new filter, and also install a quart of Lucas oil stabilizer along with the new oil.This acts as a top end lube also and helps retain the pressure in the hydraulic lifters, which will get rid of the annoying tapping sound.This stabilizer is around $14 and is well worth the investment.Do this at every oil change interval and you will be quite happy.I hope I could help and please rate me accordingly! Thanks!!!

Hi this could be either low oil, or your oil is thin and needs changing, or the tappets them selves have warn dependent on the mileage and when they get hot, the gap then decreases and stops the noise, what you need to do is either get them measured when they are cold, and find out if the gap between the tappet and rocker are correct, is this not under warranty? only 2 years old? i would take it back to the garage and find out as this should come under the warranty hope that helps
