i have a loss of compression and apparently need at least new rings, will this fix my problem? a shop i talked to told me that repalcing the rings and honing the cylinders would likely only be a temporary fix to my problem.. so what am i looking at as far as service and an aproximite cost to get this thing fixed?

 

More info , what truck , how many miles on it ?
If its any of the ones listed , your either putting a lot of miles on it , or doing something to ware early , so I would say is find out what is the cause of loss of compression .
Need the complete story to know what we are talking about , normal engine ware , or not .
If it is normal ware , then a complete rebuild , as far as just honing & rings , no one knows with out measuring & comparing to spec.s , then hone or bore / rebuild .

 

the truck is the one in my sig, it has just over 170k on it so im assuming it has something to do with the programmer im running on it, what a price range to look at for this type of work?

 

Again not enough info , tests to see what going on , what condition things are in , how they got that way .
Your still adding info a bit at a time [ no mention of programmer till now & millage ] , or the why you figure the programmer ?
I would say you need a 2nd inspection / opinion , before spending any money .
A rebuilt will vary a lot , but somewhere between
$4,500 - 7,500 + install $300+++ , if your made of money , but if you have to go that way and want a little risk to make cheaper , a used engine , but agian , I would advise getting a shop you can trust to shop for a motor , higher percentage of things going wrong with used , you should be able to find a good used engine for $1,200 - 3,500 .

 

well as far as test go we originaly thought we had an injector problem that was contaminating the crank and causing oil/fuel out the blowby. We took the truck to a reputable injection shop and they tested the entire injection system and nothing was wrong with it, they then did a compression check and found that there was a loss of compression in some of the cylinders. I figure the excess in programming (too much scarry larry) got the motor hot and is what burnt the rings, again idk im not an expert on this stuff. The motor ran fine and burned no oil until after the scarry larry program so thats why im guessing thats the cause.
Are these motors not worth rebuilding and i truly just need to buy a used or have this thing bored and sleeved?

 

You have it added up to too much fuel , testing the oil for excess fuel is what should be done , there seems to be a pattern of jumping to assumptions , in some case's founded , but before any evidence is stated here .
Such as the programing , now " motors not worth rebuilding " .
That seems to be from the semi world , where they have sleeved engines , but non sleeved gas & diesel , have been getting rebuilt for many decades .
Again , knowing whats wrong , then how it got that way , then prevention & long range plans - is this going to be a daily driver ? , or a hopped up toy ?
Sleeving cost more than normal rebuilding .
Do not forget the rest of the engine , if the cylinders are out of spec. , due to excess fuel , then the bearings are going out also , but always check .

 

the truck will be more of a daily driver, we use it to tow a toybox to motorcycle races at least twice a month, i also drive it on a regular basis to and from work, school, etc.
what are the odds of cylinders being out of spec? whats the best route to go having these things repaired? sorry for all the questions but i cant seem to find a knowledgable repair shop here in the DFW area

 

Everything /anything can wear out of spec.
I think your getting ahead of yourself , without knowing what is going on , the question of fuel in crankcase & cylinders , if there is or not .
Even if you do have some problems , you would still need to find a good shop / that knows these engines , to " 1st " do the diagnostics , then do the work .
You may want to do another thread , with the title saying anyone know a good repair & machine shop in your area .
If things work out , it could be the difference of a huge bill & weather or not there fix will last .
Also , do a search here , at top of page , stating good shop in Lubbock , Texas .

 

If the ware is normal then and the pistons are OK then hone the cylinder and replace the rings. But check the botton before you do the top.Go to a Cummings dealer for a estimate and get three in writing this will cover you when they do the job. That is three different estimate from 3 different shops==Good luck
