[excursion 1]

Recently I read an acticle on line by a well known diesel company that made a comment that newer diesel motors do not need to cool down before shutting down because the newer turbo's have a redesigned oiling system. Since I had to have my turbo replaced today, I asked the guys at the shop this question. Since these guys have been building turbo's for disesels for over 20 years I figure they know something about this topic. I was told flat out "let your powerstoke diesel idle for at least 1 minute or watch the temp drop on your gauges." The only turbo's that may not need to are the new electronic vane control on 2006 or newer specificly the durmax not the 7.3 or the 6.0. Didn't want anybody out there frying their turbo if they don't need too.
