Among the many stupid things I've done was to plug the oil supply line on my turbo 
(when I had the head off about 5 years ago), then forget to remove the plug 
afterward. I drove the car about 1/2 mile, after warming it up, and goosed it pretty 
good once - this was the only time I can recall hearing the blow off valve opening - 
scared the crap out of me! The turbo didn't sound right, and shortly after I got that 
sickening feeling as I recalled the rubber plug in the end of the line... I limped it back 
home and checked - sure enough, the turbo was getting *no* oil - the plug was the 
kind use to plug new wheel cylinders, and was a tight fit. The turbo was fine for 
another 2-3 years, and still seems tight. Guess I was lucky that time!
