OK, I screwed up, no egt guage, programer, mountains and a large load. I now have a hole in my number one cylinder.

Dealer in Oklahoma wants 13k to put in a new short block and 18k for a whole new engine.

My question is two fold. Can I just replace the piston and rings, and if the cylinder is bad just have it resleeved? How much SHOULD this cost?

Also I have easy access to the Iowa and Oklahoma City areas, can anyone recommend someone to do work on my engine?

Lastly, where can I get a good price on a new shortblock. By the way I have a 2005, 3500 with the 5.9 cummins.

thanks for your help.

Jim,
I'm sure someone will post with the name of a business in the area your looking for.
What I do know is that the 5.9 is a sleeved engine and you replace the piston and cylinders as kits. No boring needed.
You can do just one,but I would bet that in your case the others are also some what damaged.
Cylinders and head should be able to be removed while still in the chassis.
Like a in chassis overhaul in large trucks.
I would also check for a Cummins dealer for a price if you don't have any luck finding a small business to do the work.

This is absolutely incorrect. The 5.9 is a parent bore engine, it does not have sleeves.

I'm Sorry for the incorrect information. Did not realize that the Later engines were no longer sleeved. All my 5.9's are sleeved.
No wonder I don't buy anything new any more.

Thanks for the correction.

They have never been sleeved engines. They can be bored out to install a sleeve for repair purposes.

The 5.9's installed in the big trucks are liner\sleeve engines - can tell by the heavy cast timing case covers for the air compressors and etc.

8.3's, also - same bock, longer stroke, larger bore.

The lite truck 5.9 engines are parent bore castings, with no sleeve - hadta do that to lighten up to prevent the frames and bodies and suspensions from cracking, an early problem with the '89-'93 trucks

Wow,I thought I was going nuts here. I know that the 6bta I bought new in 1990 from Cummins and put in my K-30 was a sleeved engine.
However with over 200,000 miles on it I have never opened it up.
Thought the 99 ram was also,but probably not from what you say.
This is why I love these forums,Ya always learn something

This is wrong also. All B-series Cummins engines are parent bore engines. A B 5.9 in a Dodge is no different than one in a backhoe or a school bus.

The C 8.3 is not on the same block as a B 5.9. It's a much larger block.

Look in my photos i melted the number 1 piston also. We rebuilt the engine put on a htt hx35-40 hybrid turbo for around 2500 dollars but we did all the work except the machine shop work ourselvs.

Tom:

Wannadiesel is right, the Cummins 5.9 is a "parent-bore engine" and does not have sleeves! Once the cylinders are worn on the "stock" bore you can bore to 10 thousandths over and after that 20 thousandths over to fit "oversize" Cummins Pistons in the block. However,... after that, the block is considered
"unserviceable."

Cummins has a repair kit available for just such an occasion, it is a complete cyl kit with a liner to repair cyl wall.

And no the 5.9 has never been a sleeved motor.

Good luck.

Cummins does make a salvage sleeve for the 5.9 part#3904166 , this has to be done by a machine shop with the block removed. there are also pistons made in .50 mm and 1.00 mm oversize, if you dont want to use a salvage sleeve. from what you said in the other post , those quotes for replacement are way out of line. find a reputable Cummins shop or dealer.

the ISB or mechanical 5.9 has never been a dry or wet liner engine.
the ISC or mechanical 8.3 has always been a wet liner engine.
