detroit diesel 8v92 questions

And the 220, 262, 275, 300, and the "hot rod 335" too. I think this was called NH.

I remember when my uncle's Peterbilt caught fire, my father and uncle needed to tow it out from the trailer. The White Freightliner, (they were only cabovers at the time) had a broken series-parallel switch. Remember trucks had six 6 volt batteries, and the starters were 24 volt, so the two batteries that were used to step up the voltage were dead. They jumped it with my uncle's pick up, and used the compression release to let it turn easier in order to start. The sound of the engine cranking with it pulled is something I never forgot. Of course that when I learned how to drive 11 years later in a truck that had a 262 in it, and we used the compression release all the time to start it until we got the pump fixed. The check valve was a little leaky, so it took a little while cranking before it would start. Easier to crank it with no compression until it had fuel than with compression.

 

First I'm a big fan of the old Detroit 71's, 92's and 149's. They sound SO good! I own a 16v149TIB (2200HP) with only 375 hours I pulled from a genset years ago. I shoved it in a warehouse just to save it from the crusher.

Anyway,, just a heads up.... pick a couple of random parts and check out the replacement cost. I looked at injectors recently and almost fainted.

My opinion is worth exactly what you paid for it. lol

 

Do you have plans for that v16, other than a paperweight?

 

Biggest Rat Rod Ever!!!!
I wanna one-up this guy with a 12v92.

I'm thinking a mid engine old Peterbuilt. chopped and dropped.

 

Just the engine and tranny should weigh in at about 14,500.

 

The transfer pump seals are probably weak, then air can get into the line between the water separator filter and the pump, this results in hard starting, stalling until it purges the air. A truck application 8V92 should have at least 2 check valves in the system to help prevent this, sometime they get crap in them and leak back.
As to all the nostalgic rev the crap out of it information given in previous post most of that applied to 71 series natural (roots blower only) engines. the turboed 8V92s would pull down fairly well, nothing like a Cat but they were driveable.
As to fuel economy the driver is key to fuel mileage, most detroits that I have had experience with had a sweet spot. By the 92 series most of the Gasket leak issues were cured, and the oil slobber from the air box vents was about all of the leakage. Idling these engines destroys the pistons if it isn't pulling shut it off unless it has an air throttle, then idle it up until the box tubes quit dripping. (we still run 2 cycle detroits in offroad equipment)

 

The 149 was a war horse.... injectors can be rebuilt by a reputable injector shop.

 

FLC, Something else to think about if you plan on running this engine for any length of time. Cut open the full flow (primary) oil filter & remove the paper element & check it for metal. This will tell you whats going on inside.
