    What should the cylinder pressure be in a 3406e 6ts... and how low is too low before it won't ignite the fuel there for having unburned fuel smell and white smoke and missing out..

    That caustic soda probably stripped all the built up deposits off the inside of the fuel lines on the clean side of the filter, and went on to plug the injectors.

    Take a eye and hand onto your intercooler clamps first. There is a big air intake that goes through a cooler before feeding turbo. If the engine is running and one of those screwdriver metal ring clamps are loose that is a kind of leaking INTO the feed air that ruins the engine's ability to run well. (Usually when this happens at speed, It pours out 2 miles worth of inky black smoke that covers everything in brown and derates to like 20 hp.

    White smoke? I only expect to see that at about -10 or so. I don't know where you are but this is high summer. I don't know any place that's -10 right now.

    Blue smoke on start up means she's cold.

    But what do I know? All this emissions crap they piled on the trucks today means there shouldnt be anything coming out of that stack except hot air.

    Did you read the part about his fuel tank being contaminated with caustic soda?

    Just a thought - you say you rinsed the tank. With water? It's possible that water was left in the tank, and eventually made its way into the fuel system?
