Induction troubles fixed.

Went for a drive in the 80 series on the weekend at a mates property and encountered a wierd problem, when I gave it to the cruiser in 1st,2nd or 3rd gears I got to about 3200rpm before I lost all power, would start blowing a blue smoke screen out the back of the car and had a funny load humming noise coming out of the snorkel, and the turbo boost guage would read 20 inchs of murcury vacuume. As soon as I backed off the accelator everything went straight back to normal. If I accellerated steadly I could go right past 3200 no problems. And this problem I could repeat anytime just by flooring it.
When it first happened I thought it was a oil seal in the turbo gone. Then I thought the air system was blocked, my mate happened to have a small video camera on one of those snake things, kinda like a boroscope, in his work truck so we put that down the snorkel to the air filter then after the filter to the turbo. Nothing wrong.
By this time I had no idea and didn't even know where to go next, and by fluke my mate noticed that when I revved the engine, the elbow between the turbo intake and the air filter hose sucked in about 10mm. I felt the hose and it was all soft. So we hooked the camera up to look at the elbow and went for a drive. Fare enough when I caused the problem to happen the elbow collapsed totally starving the engine of air, problem found. Now all I need is a new elbow, but this time I want one that has a spring wound around inside it so it cannot collapse on me.
Just thought I would share this little experience, you never know it might just help someone.
