Have a machine that when at temperature and full idle will white stack like a train. Back it down to idle and its fine, there is emulsified oil gathering in the intake in cylinder head and the NRS cooler is wet inside
. Any idea's?

Likely have a NRS cooler that is leaking coolant. If it is original, there’s an updated cooler that will require a list of other parts to fit the new cooler. Vacuum filling the cooling system is a best practice recommendation to make sure there are no air pockets that could cause overheating of the tubes inside the cooler. See attachment for instructions and parts list for updated cooler.
