:help: I have just installed a new exhaust and down pipe on my 1994 Chev 1 ton Dually crew cab long box, and after driving it for awhile I have noticed that there is oil sitting at the end of the tailpipe. Should a person be concerned with this as the dealer says that there is nothing worng with this that is normal. I am just looking for a second opinion if it is normal or the cause of this happening.

Check the turbo for slack. Remove the intake boot from the air filter box and push it up and down left and right. It should spin freely without slop.

If you happen to removed the boot from the air filter box and move the turbo around and it spins freely with no slop is there anything else that it might me. Would it be getting extensive blow by .
