WILL THIS ENGINE WORK IN MY TRUCK

[Lcjudge]

A bit of history on my Cummins ownership.

I bought my first Cummins in a 1996 Dodge 2500. I bought the truck new and never had any issues with it. After a couple of years I decided I wanted to have a "2 seater" truck that had rear opening doors on it. So I traded for a 1998 2500 with a Cummins.

In 2003 I traded again and got a 2500 Quad Cab. All were nice trucks. I kept the 2003 until about 4 months ago. My wife had been on me as she was fearful I'd go on one of my long trips and have a breakdown. The truck had 220,000 miles on it.

I didn't want to pay the cost of a new truck and started looking for a nice used one. I really wanted a 3500 as I had begun to haul some heavier items (I collect antique cars, trucks and antique engines). I found a very nice 3500 that had 125,000 miles on it. It looked new on the interior and the exterior was almost as good.

I put about 6,000 miles on it and was driving down I-80 near Williamsport, PA and it began to miss. After a few miles it really began to run rough and I looked and smoke was pouring out the rear of the truck and the temp gauge almost immediately went to hot. I pulled over and killed the engine. That was it. It would do nothing after that when I hit the start button.

I had my brother in law come from Kentucky with a trailer and we took it home. I took it to a very good shop and they've called and said the engine is locked. Not sure what happened but it was catastrophic.

Now to the question this whole post it about. I have found an engine in a 2019 wrecked vehicle with less than 50K miles on it and I just want to make sure it will fit my truck. Here's the VIN of my truck and the replacement engines. Can some of you that know a lot more about this than me tell me, will this engine fit? Thanks.

VIN of my truck 3C63R3GLOKG691993

VIN of replacement 3C6UR5CLXKG673751

Thanks!

Can't get the VIN of your truck to come up. The donor truck has a SO Cummins and 68 RFE trans. As long as yours is a 2019 and not a HO Cummins with an Asian trans, should work.

If you’re copy and pasting, it’s probably where he has an “O” instead of a zero.

StarParts shows the same PN for a complete engine, 3041229AB, $22,555.00!

Yes, that's one of the options they've given me to get it rolling again. Out the door and on the road again is $26,600.....ouch! I've found the used engine, with 30k miles on it, for around 1/2 that. I'll probably go that route.

Just out of curiosity's sake, why aren't you considering getting the engine rebuilt, or even put some better components in it?

The engine started missing and then a minute later started running really rough, dragging down and laboring. I looked and smoke was really rolling out the rear. I glanced at the gauges (I had looked at them when it started missing and both the temp and Oil showed OK). In the matter of probably 30 seconds the temp was far into the red and there was no oil pressure. It happened very quick. It was a massive breakdown. To fix it right would require what ever it would take to fix the block as I'm sure the piston(s) seized. So, a bore on the block, sleeves or oversize, new injectors, new injection pump, new turbo, new oil pump, crank, pistons, head job (are they cracked?), etc, etc. I don't think I could do a rebuild on the engine for what I can buy a used engine for plus the weeks of time it would take to get all of this done.

…new injectors, new injection pump, new turbo,…

What makes you think these items need to be replaced? Just wondering.

Good question. The mechanic, who has worked on Cummins engines for 30 years and is THE mechanic everyone tries to get to do their repairs is positive the issue began with the fuel system. While I may not be getting all this exactly as he told me, he said he felt the injector failing created a domino effect. The injector either quit or over fueled. In either case in short order severe overheating occurred that damaged the turbo, he found a crack in it, that dumped oil into the system.

The engine, when it began to labor sounded like a tractor at a tractor pull, slowing down and pulling down under a load. Traffic was heavy and I couldn't immediately just hit the brakes although it still wasn't more than probably 30 seconds before I was able to get it over to the shoulder and shut it off. Intense over heating, a fuel issue already, I wouldn't feel comfortable spending several thousand dollars (probably 10 or more) to rebuild the engine and then try to use some of the same parts where the issue seems to have originated. I think a replacement engine is the way to go.

The mechanic told me the new engine was $22,550 but then there was several other potential issues that came from the codes he read including issues with the exhaust system and the DEF. He said I could be looking at around $26 - $27K going with a new engine. He said don't do it (and I wasn't). He doesn't like to use used parts but said a low mileage replacement engine would be the way to go. led to overheating of the engine

I’m not endorsing them nor recommending them, but a fellow I know just put one of these in his ‘07.5 and said he’s very impressed with how well and how smooth it runs. I think he’s got 2K-3K miles on it and has made one hauling run since he put it in. He’s had several CTD’s over the years. He currently has the ‘07.5, an ‘01 2500, and an ‘02 3500. He had a new ‘19 he bought just before the pandemic and sold it back to the dealer when they offered him what he’d paid for it.

I don't see CGI engines in his lineup.

Thanks. I wished that model/style engine would work as it would be considerably less expensive. The 2019 Cummins are the "newest generation" of the Cummins line. They are considerably different than prior Cummins builds. One major difference is the composition of the engine itself. Until the 2019 6.7, Cummins engines were made from a high quality cast gray iron. The 2019 6.7 is made from Compacted Graphite Iron (CGI). This iron is lighter and stronger than regular gray iron. The change over to the new engine is one of the issues I'm caught in. They're much higher in price than the earlier versions. I could get '15 6.7 with 80K miles on it for around $5500. A 2020 6.7 with 60k miles is going to run around $13K (Maybe a little more when shipping an taxes are included). I know one thing for sure, they're too darn high!

I didn’t look closely at their site, just snatched a link from one of his texts. Sorry if he doesn’t offer what you need.

I think a complete donor engine is the way to go here. It is fast time wise and the costs are fixed.
Rebuild takes time and cost is a big question mark until the final bill shows up.

Bite the bullet and be done.

Has your 2019 had the CP4 recall completed?

You will want a replacement engine that is in the same configuration as your truck was, but you also don't want a CP4.

The VIN you listed for your truck is incorrect. If the O is a 0 then it comes back to a truck that was used in Dallas with 145K on it, is that your truck?

 

[BigPapa]

Just FYI, the letters "I", "O", and "Q" are never used in a VIN.
