Question Air In Fuel

In the last week I've noticed a couple random puffs of what looks like white smoke while sitting at a traffic light. I do know that air if the fuel like could cause this but where could it come from. Same truck in my sig and first time I had driven a good 20 mile at 60 mph with at least 30 min of in town when I saw it. The second time I drove around town about 20 min for lunch, truck sat for about 2 hours then drove 10-15 min.

Oil is still nice and dark only about 1.5K since last change. Exhaust still has my Diesel Addiction smell. Havn't pulled my EGR Valve to see if intake is dry do to Ford won't have o-rings and gasket till Monday.

Any help would be great.

Air in fuel

If you are getting gas/exhaust in the fuel rails you would have a hard/no start condition.
To test for this you can do two easy tests. You can disconnect the fuel line from the filter and tie a ballon on it and roll the engine over with out useing the key and see if the ballon inflates.
You can unscrew the top off the fuel filter and with fuel just below the level of the houseing roll the engine over with the key off and look for bubbles.

You can get air/gas from a leaking fuel injector o-rings and the copper gasket. This can happen if the injector was not torqued properly.

Another place could be a leaking fuel intake line,sucking air while the pump is running.

To roll the engine over without the key, look on the passenger side inner fender near the fire wall. There will be about a 10 gage single black wire with a plug end close to the firewall. Unplug that wire and touch the end of the wire going down to the starter to the positive battery post, touch and release a few times letting it roll over a few turns.
