I've used a sleeve puller. You only need to move them an inch or two.

I have also pushed 6 out, with a bottle jack from underneath.
The first one pours coolant on you.

Different engine but I had to have the CAT C-7 replaced in my RV a few months ago. Cost was around $23K, that included new turbo and two new injectors and a bunch of other items. Was a new long block. I think labor rate was $120 but it sure took money out of our kids inheritance fund. Oh Well!

$120/hr for how many hours? LOL.

I had a 93 Pace Arrow Diesel pusher with the Cummins 8.3 250hp turbo diesel. I swapped the head out after a flange on the exhaust port broke. 170k on that sucker & I could still see the cross hatch pattern on the cylinder walls from the hone used during assembly! I loved that rig, started 1st crank for 12 years! Ended up with the 07 Discovery/CatC7. It's doing it's job! Just has the rear radiator!

As already mentioned, a Filter Minder for the air filter that never registers any restriction can be a sign that something is wrong. Another very good option to catching engine problems before they become terminal (including dusting) is an oil analysis. Good inexpensive ways to stay on top of preventing very expensive repairs, but as also already mentioned, sometimes things just go bad, but you will be greatly reducing those chances.

My filter minder reads very low restriction even with 30k on the filter even after I put a new filter monitor in. I have six or seven inch intake with only 23lbs of boost.

I agree, oil analysis allows you to see issues like dusting, high silicon, among other things before other symptom show. Very cheap diagnostic for expensive engines.

3126 and C-7 are native bore engines, no liners so they do overbore them. In fact they can even put liners in to save a block.

As to removing the liners I'm not sure. I think they press in from the top and the head(s) hold them in place. There is a spec for how much they protrude/crush whe installed.

A follow up. We did get the motor rebuilt at South Plains Cummins in Odessa TX. It turns out that they don't do any reman short blocks for this motor and the added cost and time delay was not worth a complete new motor. The total cost was right at $22,000.
Having said that I would like to make two points. First, this could have been a lot worse for us. We were over 300 miles from home but my in laws live in Odessa. They loaned us their suburban and we towed our jeep and took our grandsons on the the desert trip we had planned while the coach was in the shop. No just sitting in a motel for a week while it was being done.
The second thing is the quality of service we received at this Cummins shop. They were great. Took really good care of the coach, put things back where belonged etc. plugged it in while it was in the shop, and were pleasant to deal with. They knew we needed to be back home the following Monday and they put two guys on it to have it ready in time with no added labor costs. We drove home from there and I can't find anything wrong. Runs great.
One last thing. The day I got to this shop and the service writer was get my information and description of our problem she asked me if I might be interested in their discount parts and service coverage plan. It costs $19.95 per year and gets you 10% off of both parts and labor on any work you get done at any Cummins shop. If I wanted to sign up right then it would apply to whatever work we needed. I did and so the final bill was $22,000 less this saving. We actually paid a little less that $20,000. Maybe the best $20 I ever spent.
Oh well, it's all done now. Happy Trails!

A good reputable OIL ANALYSIS will show Silica.
I have found a lot of problems over the years. Loose intake pipes,and hoses to improperly installed air filters.
Have never had a dusted engine but have saved a few on there way.
In a gas coach I don't do the testing.
In a diesel I always run a sample.
An expensive repair and a lesson well learned.

A diesel is not something to take for granted and it can wreck your bank account.

Chuck,
Thanks for the update and I am so glad to hear that your rebuild went as planned. I love it when OP's follow up with final results. Otherwise it is like reading a long book only to find that the last five pages have been torn out.

Palehorse, I see some oil testing in my future after I get a couple of thousand miles on the current change. Until then, I am definitely stepping up some visual inspections.

B Dubya · 03-16-2016, 12:38 AM

Wow. That is absolutely disgusting,,,,and scary at the same time. Makes me wonder if the DP plunge is the right track for me. Again, sorry this happened to you!

Ramets · 03-16-2016, 05:55 AM

Yep! I have an oil test done at every oil change. So far so good. It's cheap insurance against any surprises.

One final follow up about South Plains Cummins in Odessa TX. About a week after this was all over and we were back home I got two different calls. One was South Plains main office. ( They have locations in several cities). They wanted to know how our experience was and were we satisfied. The other one was was from the service manager in Odessa. He said that they had made a mistake on our bill and they owed us $1,100 back. He applied the credit to our card for that amount. Turns out that they didn't have to replace our cylinder head, they could refurb and reuse the original one but a new head had been in the estimate.
I sure like dealing with honest people.
