I have a bender rear mount and was at the mountains this weekend. Had a problem with the sled blubbering once going up a hill and had to burn it down on a vertical slope. After it sat straight up and down for about 20 minutes or so it somehow had oil in the charge tube and blew it out the exhaust. I checked the oil every couple miles and it came out of it and ran fine after that. What do you guys think happened??

About the only way you can get oil into the charge tube is past the seals in the turbo. I'd guess that your scavenger pump didn't pull the oil from the turbo and oil pressure built up in the turbo and blew by the seals into the intake side. It is also possible that your pump shut off momentarily. You might want to check the wiring to make sure there are good connections. Also make sure that you have spare fusess for the oil pump and the circuit that you tapped the power from. If you loose a fuse or short the circuit out your screwed. This happened to my brother last weekend and we had to tow him home because with the scavenger pump down it would blow the oil by the turbo seals. He ended up having a short in his headlight that kept blowing the fuse. Rewired and cured problem.
