Just a quick question. When I switch the ignition off on my F Truck, you can hear turbo bearings still running for a good 5 sec afterwoods echoing in the exhaust. Is this normal or not. Im interested to know before I have it off, just in case I need to have it fixed along with the other stuff I am doing. Im a bit reluctuant to take it to anybody up here, as I seem to struggle for good mechanics that know anything about them, or want to know. Thoughts!!
