DT466E - Milkshake oil

Ok so a couple of months ago I purchased a second bus from Broward county schools, a 2006 RE amtran, DT466E, MD3060 with a/c !!! Originally I bought it for parts but the body is in perfect condition so I change my mind on cutting it up.

Absolutely zero rust on this baby but....is was sold as a non runner, got chocolate milkshake in the motor...

But hey, only 177,272 miles !!!

So my questions are...





A: Can I drain it, put new oil/coolant to see if
  1. will it start and run?
  2. check to see if tranny goes into gear
  3. check a/c system.
B: Can I drive it very short distance, just to move it in my parking lot without worries of major damage? It will not be driven on the roads, just want to move it to a better spot to work on it.

C: What is the best method for cleaning out the block? I think I read somewhere before that dishwashing soap.... Calgon maybe ??? I don't know so I'll ask straight up... What the best way to flush the motor?

It doesn't take much water to emulsify your oil. If you change to oil and filter you should be able to move it a short distance. Check the oil again after moving it and try out your A/C. You might find that the water problem is something simple to fix or...
Good luck

Thanks for replying...

I pulled the drain plug on the oil pan already.
I was thinking about letting it drain for at least 24 hours, add another gallon and let that flow out, change the filters and fill it back up again.

I've read quite a few posts about others driving (unknowingly) while the cooler leaked and milk shaked the oil... but I guess I just needed to hear it from someone else...

Let see if I can get lucky for once...

On Millicent's Cummins 5.9, it was the oil cooler.

Many changes of oil, before it ran clean. I used the cheapest non-diesel oil the first few times, and gradually worked my way up the $$-level to my usual full synthetic Rotella again.

Many flushings of cooling system with Simple Green in the water. But years earlier, I bought a can of something that was made specifically for flushing out oil from cooling systems, and it worked very well. Somehow, I was unable to find that stuff this time.

No photoshop.... real bus!
Not counting the drivers window it's 15 passenger windows.
My other bus, #9906, is 14 window.

I am hoping I could be so lucky... Guess I'll find out in a couple of days!
