They agreed to re-credit me the roughly $1,200 already paid in Montgomery...  The tow bill they are laying on me.  I have requested a copy to send to my roadside service company.

It looks to me that those are different cylinders the one that is busted doesn't show the fuel burn pattern on top of the piston.


GOOD EYE!

I think the diagnosis is going to be that a complete rebuild is called for.  Hope I am wrong.  Are those cylinders badly scored?  He used to have good compression given  "no smoke" and "good" power.

Would you have paid 6-7K more for that bus if you had to?

I really feel for you, makes me afraid to go more than a couple hundred miles from home.

Van,

That is so scary.  I didn't notice that there were two different type pistons.

My eye is failing, still. :(

Let this simmer on the board for a day.  More info and advice can't hurt at this point.

Really sad to see this.  Are the prices in line?  If BK is still speaking to us/me I think he might have an idea of what is the norm.  Call Luke at US coach for opinions and answers.  What would Choo Choo charge or is the water too muddy for even a comment on that.  Smart to stay far far away I know.

Ten years ago the machine shop charge for sizing and straightening a con rod was way less than replacement.  A bent rod gave a distinct signature on the cylinder wall and piston.  Different with DD?

That's the cost of one hole? Ouch! What about finding a good used take out or do a re-power with a 6V92ta? If I were to start spending that kind of money I would want something with a little more scoot put back in.

I spoke with Clifford a little bit ago.  He assured me that with using genuine Detroit Diesel parts, that bill is in line.  He also figures that give all that has happened and all the trouble we had in Montgomery, that they would make sure it comes out of there 100%, checking bearings, etc.. 

There are people out there a lot worse off than me in their buses.  Hopefully I am getting my big "ouch" out of the way quickly.

I think they are all dished if you look at them closley. The piston that is busted has no fuel burn pattern at all. Whats up with that? If this was a new problem wouldnt there be old burn pattern on the piston? confused here. Maybe clifford could answer that one.

Another question is if the valves where bent would they be closed all the way? I have seen many bent valves in auto heads usually the valves do not seat flush after being bent? Just been studing the pictures.

Just one of the finer points of owning such a machine. Granted it sucks and we all shiver thinking about going through just such an ordeal. Wasn't it last year that Bob of the North got a total rebuild at Lukes? I'm sure there was some puckering factor there also but it wasn't like someone taking advantage of him. It is what it is. I don't know what your position financially is Marc but if I was in your position I would go the total rebuild route, save the documents and be on my way. If that bus had a documented rebuild with whatever quarantee goes with it before you bought it would you have kicked in another 10-12 grand? Any upgrade to a 92 or 60 series will involve more than a rebuild of the 71 and then you are still talking used. Sounds like you have good heads. 5 or 6 grand is almost 1/2 way there. It won't hurt to ask. Later
