Here's the heart of the beast. A turbocharged 2 stroke Detroit Diesel. "Screaming Jimmy."
So skoolie.net, got any tips for the first time you fire up a 671 after 10 years?
So far, I've pulled the batteries, 2x 8D's and put them on the desulfer battery conditioner thing, but am not holding my breath on that one.
There's oil in there, black as the night, but not "cloudy" or "milky". There's a half tank (50 gallons!) of ten-year-old diesel, but I'll start it off a jerry can with fresh fuel.
So Detroit Diesel fans out there, should I just crank her up once I get some batteries, or what? Pull and clean injectors? Drip some oil in the bores? Or just f-ing go for it?
I had a yanmar diesel run away on me once. No fun. I stopped that little guy from blowing itself up by putting my hand over the air intake. What's the emergency shut-down procedure on a 671?
Hello there and congrats on your Crown! Like you, I recently acquired a Crown , a '76 with a DD 671 NON turbo and fuller 5 speed. I have learned much about the bus and its special engine from the fine people on here. One thing I learned is the DD has and emergency engine stop lever in the driver side engine bay. I never noticed it until someone on here sent me looking for it. Mine looks like a pickup truck dipstick sticking out of the center of the horizontal frame rail, center of the bay, almost directly behind your turbo. Once I saw it, it was even labeled. You may have to be close to use it but you could tie a nice long rope to it to be farther away... lol. I would also agree with the co2 fire extinguisher as well.
As for starting it, I found my Crown where it in a dirt lot in Yuma, AZ where it had been parked since the California registration expired in 2009. I cleaned the air filter, put in new batteries, checked and topped off some fluids coolant mostly. It had a quarter tank of fuel so I just added injector cleaner and decided the only way to know if it was alive was to turn the key. Just like your 81 with 500k, mine had 479k on the clock and even then, it stared faster than my newish chevy 2500. Sounded like a dream. a little smoke but after 7 years of sitting and old fuel and no service records what do you expect? After checking the brake system for leaks and properly airing the tires at the nearest Loves, I drove it 200 miles to her new home. Good luck with it bud!! Keep us informed on how its going!!
P.S. I would VERY HIGHLY recommend you read some other diesel forums as well about your very rare, very different, but incredible engine. You CAN NOT get a replacement engine so learn about it and take proper care of it!
