KTMGuy90 Hey Guys,

I agree I am going to put in a new long block. At this point I am just trying to find who to get the motor through. I am leaning towards this longblock - tow build listed below for the 6.7. Let me know what you guys think? Thanks!

Cummins engine street/tow
5.9 $6500

6.7 $7000 Longblock carry out with core.

includes ARP head studs, street/towing industrial injection camshaft, Manton valve springs 103#, Manton pushrods 7/16, Colt cams lifters, 12v hardened rods with arp bolts and everything our stock engine comes with. install prices are the same as our stock engine.

lower egt's

improve low end boost response

strengthened valve train

head torqued tighter and more evenly

more durable 12v connecting rods with arp bolts

gain fuel mileage by 1-4 mpg dependin

JRD Coming from a guy who had a 5.9 rebuilt by one guy and the head freshened up by another guy...I would have saved time/money and headaches just getting a long block from a shop (not a guy that builds engines) that builds these things every day. The engine burned oil when it was fresh and I attributed it to rings not seating yet. Hooked to a trailer and towed up some good hills on a highway so I can vary RPM and load for break in and changed oil. 30k miles later, the engine still burned oil and the head guy was blaming the engine guy, engine guy blamed the guy who built the head, then they both argued that I didnt break the engine in correctly and it was my fault. I tried to explain Cummins builds these engines by the thousands and they never need an appropriate break in as some hot shotters buy one off the showroom floor, hook their loaded trailers and immediately put the truck to work with no problem... In the end I was left with either selling the truck and telling the new owner about the oil consumption or spend another 5k on an engine that could've wound up the same way... I sold the truck and bought my 2011. Just buy an engine that's dang near complete (long block) or a known used engine that's factory Cummins. Dont fall into the "this guy builds lots of engines" crap. It's a tad more money but in the event something goes wrong, you're money well spent. And if you go against my advice and rebuild the engine, use factory Cummins rings. Not chromoly rings. Good luck and let us know what you decide.

Wibb If you have it rebuilt, I'd have them put a good gasket and studs in from the start. Cheap insurance.

KTMGuy90 Thanks guys.. I know it is going to be a long battle with the service agreement/warranty company, and the dealer who sold me the truck. I should have been a little more patient... lesson learned..

Anyway here is the diagnostic i received on the motor:

Let me know your thoughts..

pocketgunner I think there is traction there for that argument for sure, uphill long battle but they may end up rebuilding it then again after an extensive fight they may still say nope it was deleted and deny the claim.

ritchie1087 i would make the dealer you bought it from rebuild it if they sold it to you deleted and gave a warenty id say this is how i bought it from you i havnt touched it you can fix it

KTMGuy90 Good advice, thanks pocket runner. This is the direction I am headed.

KTMGuy90 Yah, I have contacted Cummins dealer in Grand Junction and gave them my serial # of my motor. I have heard from a shop they have had bad luck getting a re-man from Cummins for the $. I think I am better off having someone build one out if I am going to be putting this kind of change into it! Thanks for the reply tho, really.

pocketgunner There are a few companies in Texas that have been rebuilding nothing but diesels and mainly Cummins engines for 20 plus years. A rebuilt short block is $32-4000 I believe, your current head surface may need to be machined flat depending on how bad the damage is to the motor and what all let loose. I would look around for a builder whose been in the business for a long time and go that route. Now you can really REALLY drop some cash if you dive into the built motor scene lol its all in what your goal is for the truck end of the day.... tow with good reliable usable power OR make as much power as you can.
