Unhappy uhm...air filter sucked into turbo

I just bought this truck and the original owner had a foam air filter. I didn't realize this until I was changing the fuel filter and the truck wouldn't go over 20 mph. I saw diesel leaking from the turbo and when I investigated I found a big black ball of foam. The truck won't go over 40 mph now that it has been removed and replaced with a paper filter. Around 40 mph the turbo starts doing its thing and sounds smooth, but it won't accelterate and hangs out around 2000 rpm. I'm new to diesels and I'm not sure where to start with this one. Also, I have been through 3 brass water seperator drain valves trying to get one that doesn't dribble. Is there any tricks for these things

Thanks,
Travis

Sounds like there is still a restriction in the intake or exhaust if it wont spin up above 2K, take the exhaust off as close to the turbo as you can and fire it up again, if you have speed then it prolly a plugged exhaust, just hope that foam didnt get too far into the engine..... Auto or manual?

It's automatic. Where should I make the disconnect, off the turbo itself? Sorry im new to turbos too.

According to his first post, the exhaust doesn't enter in to it.
Supaconducta, if you pull the snail off, that's the aluminum piece with one bolt holding it to the intake manifold, there will be a screen under it and I'd be willing to bet it's got a major pile of foam trapped on top of the screen blocking off intake air. The original filters that came on these turbo models had a paper filter with a foam layer lightly glued to one side of it. Sounds like someone installed one upside down, the foam side goes DOWN facing the dirty side of the airbox.

Thanks guys for the info. I'm guessing that when I pulled off the intake to take out the old paper air filter and put on new valve cover gaskets that I flipped it over after i took out the filter and the foam went into the other side. I never thought to look for foam in anything but my lawn mower. It was a little hard to tighten but i was fighting a family of octopi in the wiring around it. Mystery of the heck that got in there solved. I hope I learn this lesson on the cheap. I'll be pulling her apart in the morning.

its all betterish

Before I continued to butcher this beast, and attempt to dismantle the turbo, I took it to my mechanic. Busted Throttle cable was the culprit to the acceleration issue. I'm hoping the foam was crumbly and dry so it probably just got obliterated by the turbo and shot out of the exhaust. The gas pedal was hard to push when I first got it but it moved pretty good until the filter issue. I guess the stress from having to floor it with the loss of air from the turbo clog made the cable give.
