Went to do coolant change..found lots of oil in degas bottle, a local general mechanic checked it and said it was a bad oil cooler.. what exact test he did i do not know.. he doesn't think it is a head or head gasket..
My question is, if the oil cooler and possibly the egr is bad will either one of those -or- a combination of those make it smoke out the tailpipe at idle..
Smells like oil smoke- not water vapor
Truck has never or now run anywhere near hot and still runs good..
Thanks in advance
