I HAVE A P-3500 STEP VAN WITH A 6.5 DIESEL ENGINE/NOT TURBO.

It starts and runs very well, then after a few minutes, white/gray looking smoke starts to go from light to heavy, but it still runs fine. What is causing this? I have been told that it could be EGR vaulve, but it is ok. Where do I look next.
