lost boost

timmy · #1 (**permalink**) 04-03-2006, 12:50 PM

hey guys hoping someone can help...driving home today my 6.0 lost all trace of boost,out of the blue it didnt act up at all! Thought I blew off a tube but everything is ok, the truck runs ok other than the turbo doesnt spool up. Not getting any black smoke from the exhaust indicating a bad turbo...was running fine yesterday topping out @30lbs...perhaps a sensor that controls this particularly complicated turbo???

Gosh i really hope the compressor wheel didn't eat a chunk of something... the very first thing i'd do is pull the large (5" diameter of so) hose from the air filter to the turbo off and look at the vanes inside the turbo. Do the edges look uniform or are then twisted up? second reach in there and try to twirl it with your finger tip should be able to spin it with one finger.

Marc do you think his exhaust-to-turbine V-pipe blew out? i know two people that have had that happen.

its possible...but i have not seen a leaking Y pipe that caused a total boost loss...just an exhaust leak with some power loss.......Marc
