i would try cleaning or replacing your cdr valve. it is the tune can looking thing behing the intake. acts like a pcv on a gasser.

also check air cleaner. that being dirty will make the cdr try and pull vapors from crank case.

it is a round tin looking thing that connects to the intake. pulls vapors out of crankcase and into intake. has a spring and rubber diaphram inside it. the rubber part goes bad. let me see if i can find a pic.

I cleaned the cdr valve but wen I pulled it out the hoses was so brittle it shatterd. I replaced the hoses but they wernt the hoses for it (temporary fix) all the auto places don't even have a listing for the cdr valve. After I put it bac togather the truck still blows blue smoke. Yyyyyyyyyy. I kno the injectors r bad cuz I have a fuel knock. Where can I get the cdr valve and hoses and how do I stop the blue smoke.
