Broke down in Fallon NV

[thomasinnv]

you can up grade to a bigger motor since it costs the same for r&r and its just the cost of 92 series which is about the same as a rebuilt 8v71.

I had considered this but decided against it  due to the fact that I need it back on the road ASAP, and being an MCI I really don't want to have to deal with the extra heat from the turbo'd engine in an already marginally cooled coach. I would rather spend the money on a rebuild than on a used engine with no guarantee of condition.

Depending if all the coolant ended up in the pan, you are looking at the following.

1. Head gasket blew the o-rings under the head
2. Valve guide could be loose
3. Copper injector tube, like originally stated.

Determine how much coolant was lost first, the more of it that ended up in the pan the more than likely its #1.  Make sure your mechanic is using genuine Detroit parts and more importantly, find out his warranty.  I bet his warranty from where he is buying the parts will be 90 days.  Ours is 1 year, 100,000 mile parts and labor, on the parts we replace.

Our in-frame includes the following
Cylinder kits
rod and main bearing
Head set
$9,000.00  (labor included)


Parts only for items listed above.
$3,500.00


A 8V71 re-man engine $12,900.00. 1 yr/100,000

If the warranty is important to you then you need to get that figured out before you start.  We would be more than happy to help where we can.  We just want to make sure you get taken care of the first time.

First gear clutch pack is wasted, quite a bit of material in the pan. Gonna be a complete rebuild of the tranny. Looks like we will be exceeding our funds we had set aside for repairs, but we continue to praise the Lord and have faith that He will make a way where there seems not to be one.

The failure turned out to be rotten head gasket o-rings. The engine is mostly back together, transmission supposed to go back together monday. Differential checked out good other than needing new axles which are supposed to be in tuesday. Good thing I have a place to stay while the work is being done. it's been a month so far and will likely be another two weeks.

Yep wrong antifreeze the good old WalMart antifreeze will do it every time

luvrbus, what is the correct antifreeze?

It seems Supertech [Walmart] is supplied by Peak and Prestone.

Well to be totally honest, I was lacking concerning the maintenance of the coolant. In the five years I ran this engine I never did change it and the ph was never checked. that coupled with the fact that the last rebuild was 35 years ago I am kinda surprised it held together as long as it did. When I'm done with this go around you can bet there will be nothing spared when it comes to maintenance.

[thomasinnv]

Degreased and pressure washed the engine compartment today getting ready to put the engine and trans back in hopefully next week. upon inspection of the rear frame there are several gussets that are cracked or rotting away. I have a guy coming this afternoon to look at it and determine the best course of action for repair. The guys here at this shop are all welders but they don't want to touch it because it's all stainless, the guy coming to look at it is supposed to be a master fabricator.

Standard timing, n70 injectors. What would be expected hp and torque? And what timing pin would be recommended?

[thomasinnv]

Flew into Reno last night. As soon as the sun comes up gonna do a walk around,  check fluids, and point it south. Been a long time coming. What was supposed to be a 2 to 3 week job turned out to be almost 5 months of heartache. Praying hard I make the 620 miles with no problems.

Wow Thomas, 5 months? I know you had a lot of work done but that's incredible. If I ever have serious trouble with my 8V92TA, American Fleet's rebuilt will be the way I fix mine.  What was the final cost of repairs??  I would run it around close for a few days before I got too far from repair shop to check for problems as I've found there is always some little issues pop up and the road ain't the best place to find them. Take care and good luck.

Time gets away from you Glen I have one I am finishing up ,the poor guy bought a engine and transmission from a shady E bay seller that was supposed to be  a 75,000 mile engine that was total junk
Then he had to deal with the trucking co that broke all the components when they flipped the engine on the dock. He only got a few bucks from that ordeal which took months and no where even close to pay for the parts.

Then we needed some OEM parts that took for ever to get. I had to use both engines to build one and still waiting a few parts it's taken well over a year but I can see the train coming.I know Derrick had some of the same problems and is probably over budget big time.
Like you say I would go find me a long grade and work the engine before I took off on 600 mile trip with no towns or service in Nev for 200 miles.My guy is lucky I am not charging him labor just trying to help him out in tough times

Your a goodun Cliff helping folks the way you do as I've learned a heck of a lot from you on my 2 stroke. I would jump on a complete motor or trans if I needed one and wouldn't look back.  I'm the most impatience fella around as my lovely wife puts it. Probably have to hock the wife but you gotta do what you gotta do. 

[Scott & Heather]

I can say without a doubt if our 6v92 goes on the 9, I'm stripping the bus and scrapping it. If the 8v92TA DDEC II goes on our 102, it's getting a 4 stroke. And a good kick in the rear bumper for letting me down.
