Blown up Cummins 5.9

[JP135]

My 2007 1 ton Dodge with a 5.9 Cummins in it and 175k miles on it gave up the ghost last night.

Driving about 70, heard motor knock - fast & light like lifters in a motor running low on oil, pulled into a parking lot and shut it down. By the time I shut it down, the knock had gotten deep and solid. Not running hot. No puddles of oil or any obvious damage to the block. Had oil in the crankcase (although I noticed it only had 45psi oil pressure as I shut it down). Had a buddy tow me to another friend's shop.

This morning's diagnosis: Either a hole in a piston or a rod.

Anybody got suggestions? After doing some checking around, got prices ranging between 5k to 10k, then found a shop in Kaufman with rebuilt longblock for $3250 (exchange) w/6 month unlimited mileage warranty.

Is that about as good a price as I'm gonna get? Any other suggestions I ought to try out before buying a longblock?

I'd say its time to buy a new truck.

If you had something bad come apart, all that metal shaving went into everything, all bearings, into the head, into the turbo, etc....

Plus swapping motors in those things is a job. That motor is freaking heavy.

I'd figure out what caused the problem first of all, then look at how to fix it. Pistons don't just wear out. If the cylinder wall isn't cracked you may be able to replace just a piston, it'll be a lot cheaper than doing the entire engine.

Nothing.



Agreed on the lol at getting a new truck. I think I'm done with "new" trucks. I really like this truck and I've put every mile on it since it was new (which didn't seem to count for much last night...). I wish it was a six-speed, but way too much work to swap it over from auto.

Good points. I may take it to a diesel-specific shop and get a more in-depth diagnosis. The shop its at is a great shop, but they're real busy and I don't think they really want to have it taking up space in a bay for a lengthy tear-down/repair.

Dj could very well be on to something, it needs to be diagnosed

main bearings seem to go before rods on the Cummins... hopefully it won't take much to overhaul it

[War Machine]

Ill buy as is, send me a message

It will probably be easier and cheaper just to find a complete low mile engine rather than rebuild it. That's what I've done for a couple.

Get a nv5600 in there
