Can I drive my Duramax with a bad turbo?
The turbo itself is fine, so it’ll still spin and allow air thru, just less of it…..and the vanes aren’t busted, so no worries about running shrapnel thru your motor. As long as the blower can spin and theire’s oil running thru it, then like everyone else is saying, you’ll just have less power.
What kind of turbocharger does the Duramax LB7 have?

Is the air intake on the LB7 Duramax too restrictive?
The factory air intake on the LB7 Duramax is nothing to boast about. It’s restrictive, and it’s basic design can actual hinder performance more than it helps. Many LB7 Duramax trucks experience higher intake air temperatures because hot air is being pulled from the engine bay. The stock filter is also too restrictive.
