Hey I am a new member, just stumbled on to this forum. My 2001 7.3 diesel has developed the irritating habit of smoking on startup. I think it is blue smoke, but could possibly be more of a fuel smoke, as it smells strongly of diesel. When the engine warms up to operating temperature the problem disappears. Just wondering if anybody else out there has had a similar problem and what they found out about it. I have just rolled over the 235,000kilometer mark on the odo. Any help would be greatly appreciated. Thanks in advance guys and gals!
