8v92

I'm a big fan of these engines, so I'm biased. Like someone esle said, make sure you run straight 40w oil, Delo 100 or equivalent. The ash content in Delo 400 is too high. These engines require more maintenance than what you may be used to, for exemple, on non-silver 92s such as this, rods and mains should be changed every 250-300,000 miles. Also, do not idle this engine for extended periods of time like you can a Cat or Cummins.

 

Not 40w but SAE 40. There are also multigrades (15w40) that work with 2 stroke Detroit but they are very expensive.

 

Yea deffently stick with the straight 40 wt and 30 wt oils no mutli grade ils period! The delo 100 would be the best oil for it kinda hard to find but its around and delo 400 is pretty good too. the shell rootella is good but the delo is betta. just take good care of ur 8v92 try too address all the issue when u can soo they dont get worse in time and just keep it well maintanied with the right liquids and filters and such and it'll last for good while. These engine's are alot of fun but very nosiy but if u like noise and somthin that sounds like a race car when shiftin then ull enjoy this engine. The highest rated 8v92 i can think of is the 8v92TTA its 475hp. Ask the old timers about these engines they'll give the scoop and good advice. Ohh and here's a picture of what happens when u use one oil from the other just to give u a idea.

The picture that show the radiator cap, I don't like, If it was me I'll drive this thing till it warmed up, if possible with a load, that orange stain looks like the coolant is being pushed out trough the cap when hot and reving high, if that's the case you might have a pitted liner and when hot will expand enough to cook the coolant and push hot air thru the pits putting pressure on the radiator, but not bad enough yet to get coolant in the oil.

How do I know? well after buying a truck from a "friend" that only needed a radiator cap, I found out that it did, plus an inframe.

 

I'm considering the purchase of a fire truck. Ive seen units with a 6v92 and others with an 8v92. I've never owned such a large piece of equipment. These are old but usually low milage engines. They "should" have been maintained correctly, since they were emergency equipment on tax payer expense. They are typically equipped with an allison automatic of some type. Any advice for a newbie?

 

To use or to show?

 

I don't think so I have seen coolant older than 6 years and they never looked like that, they might not hold their properties but the color stays the same.


ask the guy to flush it and then run it with the new coolant, but it will take a good run (long) to get it rusty again, but you have to get the motor hot and see if it over flows, if it feels thicker than water and it has that rusty color to it, I will be worry,

I would like for others to chime in on this.
