smell

[TheKing]

Hey i just got my first diesel and while truck is running i smell a real crisp smell not like diesel fuel but like a clean burn of it. Is that normal...ive just never smelt that with my father n laws 7.3 also never had his ran in my garage befor either so was wondering if normal or should i be worried....also there is a long spooling sound(which is prob turb once again new to the diesel) But i always let it run for several minutes to cool down the turbo before i shut off the truck.....give me your thoughts on the two!!!!!

Crisp like in bacon? Not sure what you mean by crisp. Does it smell sweet like coolant? The long spooling sounds like the turbo just as you suspect. Letting it cool down is fine, but probably not necessary except after running it hard, like when towing up a grade for a period of time. Then, I would let it cool down, otherwise, I don't bother.

clean sweet

Everyone is different but I always let my turbo cool down to 350* before shutting it off. It only takes a couple of minutes when hot and almost no time when it's cold out. It will help prevent coking the bushings.

There should only be a couple of second delay at most from starting the truck to the turbo spooling up. If it takes much longer the vanes in the turbo are probably loading up. Take it out and run the heck out of it to get the vanes working. If that doesn't do it you will have to tear into it and clean it up. A sweet smell I would guess to be antifreeze. is it smoking and if so what color is it? Get something to monitor the engine like an Edge insight so you can tell if your oil cooler is operating correctly. Monitoring ECT and EOT is the only way to know.

no smoking at all and truck runs great didnt know if it was from a high cetane rating or if that mattered
