My 2012 tacoma 2.7l 4wd taps when it's very cold outside at start up and does it for about a minute to 2 minutes. I have only had it a year. It didn't do it last winter but I changed my oil myself until this last time and I let toyota do it and now in cold weather it taps at startup. I used a full synthetic so could be that they used a semi synthetic. Everyone says all 2.7s do this and that it's the hydraulic lifters. I plan on changing the oil myself again and using Mobil 1 full synthetic. Has anyone else experienced thos before?
