I have a 91 international 4900 with a dt466.the engine started to smoke black,& gray.under load.Also when taking off from a stop.When putting your foot on the pedal it smokes alot.When you start the truck it's hard to start almost like the fuel isn't there.Had compression coming from the #6 thru the sleeve. The sleeve was replaced. When releasing the line going to the injecter on the number 6 line it does not miss all other lines miss.

You can smell alot of feul and it's coming out the exhaust I belive into the turbo.

Would like to know any idea's from anyone. If you need more to go on please let me know.
