I bought my new 2014 Escalade in Dec 2014. I am in New England. Recently, I noticed some engine noise when accelerating in cold days. Extended warmup time can relieve significantly, but the noise still persists. Anyone in the same situation?
Sounds like piston slap. Does it disappear after it's completely warmed up?I bought my new 2014 Escalade in Dec 2014. I am in New England.

Start the engine and let it complete the first leg or two of the fast idle sequence. Then shift into gear and drive normally, avoiding full throttle operation, until at least 10 miles have elapsed. The coolant may be warming up, but the oil is still as cold as a rock at 6 - 8 miles. Complete warmup is when the engine oil reaches its ideal operating temp of 185 - 210 degrees - and that takes quite a while in cold/cool weather.What is a complete warmup?
