Yea. I had a 88 Celica All-trac turbo back when it was new and I had to do that. Before the turbo timer days. I don’t know why I still do it. Maybe to allow the turbo to spin down or just, like you said, and old habit. No harm no fowl anyway.Old habits die hard but this practice is not needed. Modern turbo vehicles circulate oil and coolant through the turbos after engine shutdown.
