Broken down, toasted engine??

[Geom]

George, you can tell if your engine is aftercooled by just looking,if you see a 1-1/4 pipe coming from under the blower (governor) from the block going to the T stat housing it will have a after cooler he should know that,if you only have the one crossover pipe tying the 2 heads together then there is no after cooler    

Thanks for the info Clifford. It's kind of hard to tell for sure, but I think it does have one.
I see one thick pipe running from one head to the other (originating from what I believe is the water pump and also where the temp sensor is installed. Midway between that pipe there is a teed-off pipe like you're describing (about 1" ish in dia) going down into the area where the blower would be. I don't see a "return" pipe/line anywhere (at least not one of equal size). Just the one pipe going toward the blower.

I'll try to snap a couple of pics and post them tonight or tomorrow.

There is no return pipe it returns from the after cooler directly to the block

George, I'm kind of in the "how much do you pay them to tell you your engine is toast" instead of putting those $$$ towards a rebuild or replacement?

Back in my day you payed nothing...you payed to have things fixed. smh.

Flat rate for an 8v was 48 hours...and diag was included in the tear down...

and that included steam and hot tank and pressure testing heads and block...SMH..

oh and cold tank the blower...

Lots of less cost to find a good used engine and don't worry about that one.  You know it has bad problems and a rebuild will be at least $15,000.  Good used engine should not be more than $2,500.

Good left handed used engines are getting few and far between now, and George has a 8V71TA those are real hard to find

I bet you popped a head. You already know the engine is worn out so it's probably time to bite the bullet and rebuild. Left turning 8v71t is going to be next to impossible to find. I wouldn't write off the crank until they check it, they are pretty tough, it just might surprise you. You might only need a head, aside from the normal rebuild parts.

[luvrbus]

For some reason the tilted 8v71 are hard on cranks,everyone I have seen, I have a good left handed crank if George needs it but it took .020 to clean it up which is not all that bad it is still in DD limits, the crank is 20/20 mains and rods journals

Interesting, i did not know this. you learn something every day.

[luvrbus]

I think it is because of all the parts needed to turn the fan on the front of those engines Derrick.lol I know I hate working on 1,you need knee pads for the lower part and ladder for the top but I do like my GM friends anyway even if they do walk sideways 

[thomasinnv]

Sideways and backwards lol.

I think some of you are confused. Look at the bottom of Geom's posts, it says he has a 6V92 turbo.

Good luck, Sam

Good point that adds to the places where water can enter the engine, I feel for the guy anyway

He has a 6V92 turbo.

We have reason to believe that it was a fresh rebuild old stock from a transit system when we purchased the bus. The oil in it was still clear and it acted like a new engine. I doubt it has 20K miles on it. Could be wrong, but it sure looked like that.

He purchased yours and Don's bus right
