What Really Makes 12v Cummins So Terrible?

[@ppump24valve53]

My first block that was original with the truck was a 2000- 53 stamp, and it was cracked when I bought it, ( reason I bought the truck) 260 k miles. patched it and ran it for a year, then cracked in front towards the oil cooler, and I said enough, and found a 56 storm block, and this is when I did my P7100 conversion , and built my engine. All I can say is, man it’s awesome, not having to worry about reliability issues at all anymore. I also have Power Driven DIESEL’s Predator mechanical lift pump, ( which is a CHAMP), had 2 Airdog pumps, n they’re just simply not made for the kind of pressures the P7100 needs

I bought a 1996 12v out of a bluebird ford bus for my truck conversion. I have a 97 f350 it is currently in. Love it works great for what I need.

Back in the early to mid 2000s I bought a 1990 reg cab 4x4 diesel for a really good price and a old welder I worked with loved those trucks and that's what he drove. He told me about pulling hills and how the truck loved pulling hills but they would over heat and blow the head gasket. He was totally right because I was loaded down and there is a long steep hill that would take forever to climb driving any truck from that era because they just didn't have the power. That Dodge was actually was gaining speed going up that hill and was totally impressed till I looked at the temp gauge 🔥 the blown head gasket symptoms didn't show up right away but they did. I knew some mechanics and got myself a bolt stretch gauge and a head gasket from Canadian Tire and did my very first head gasket on a diesel. I had lots of practice on small block Chevy's.🤠 That truck got such good fuel mileage and I broke everything on it mud bogging and hill climbing and river driving. Do not drive fast in deep water or the water will get sucked into the intake and blow your head gasket 😦

[@Bloodbain88]

Great video, I pulled a 12 valve out of a Ford F-800 box truck for my swap I'm currently doing. Been watching your videos to help learn about these engines. A church owned the truck and had everything (turbo, P-pump, and engine) remanufactured shortly before I bought it. The owners manual states 230hp and 605ft lbs of torque, is it ONLY the pump that gives it those numbers from factory or will anything else be different, like injectors or cam? I tried looking up the numbers attached to the pump but they don't correspond to anything I could find. So I don't know if it's a 215HP pump that's factory tuned to 230 or what. Seeing that it came out of a heavy duty application it's got a bunch of weird stuff on it. Like it has no vacuum pump just a big power steering pump that hopefully doesn't blow up my somewhat smaller hydrobooster on my K30. Just curious really, the engine runs fantastic so I'm just gonna chuck it into my truck and run it.

[@CUTTERUPROB]

The 230 pump is different inside the 215hp pumps. But it can be used it just doesn’t have the some potential

[@thenomad7120]

My ‘97 12valve…the boost seems to top out under 20psi but only sometimes. Can’t find any obvious leaks, have plugged wastegate feed port and checked the flapper not stuck open. I’ve never wound the turbo beyond 26psi I’m not into speed just reliability and towing my 5th usually under 60mph. The inconsistency of turbo response to throttle has me puzzled! Thanks (born in Calgary)love your channel 👍

[@moltenmetal5645]

Glad i found this channel. I have a project build and i want a 12v p pump as the engine. Somewhere around 400 rwhp so nothing extreme. Will be on a post 2000 1 ton chassis with a 50's body, what kind of MPG can i expect out of the 12v?

[@CUTTERUPROB]

Depends on the trans / gears / tire size. But 20 mpg ish is common

What are the cooling modifications you talked about. Mine temp climbs bad when towing long grades. I have seen mine go from 170 at the bottom of a grade and be at 240 at the top. What should I do, I was thinking about building a water mister in front of the radiator

[@CUTTERUPROB]

coolant bypass helps , running 200 tstat is a good idea as well and on your truck i would pull the rad and clean it i bet it's dirty witch won't help

[@thenomad7120]

New radiator for couple hundred bucks solved my running hot towing long grades or in traffic issues on my ‘97.

[@brcron007]

Rob are you saying "Fleet Style" ? For the bypass mounted to the rear of the block that would include a thermostat. I like that option and sounds and would seem more efficient. I'll be sending you an email in the not to distant future for consulting on my rebuild 92 w250 stock for some more of your tips to add to the build. Like what you mention in this video. But we'll talk. Mileage and efficientcy is the direction I'm going. Thanks.

[@jimmiller4951]

Another great video Rob as I will soon be changing my head gasket . So you know , I do not have a Dodge pick up , I have a 1991 Ward Senator school bus converted into a toy hauler that am going a major step further and converting into an RV ( retired RV Tech ). My 12v has a Bosch VE distributor type pump with an aftercooler and there is very limited info out there on this type of 12v only ib marine applications. I dont have a question at this time just letting you know what I have , well perhaps a question..... Are yo familiar with the aftercooler on a 12v and if so your take on what I may need to know ?.

[@CUTTERUPROB]

I have played with a bunch of the pumps ( all the ones I know that were used ) so I should be able to help

[@matthewlengyel764]

I have a hard question to ask. I rebuilt my 12 valve cummins and installed head studs. Lasted 4000ish miles. Uses my well used craftsman torque wrench when rebuilt it. I went to check my bolt torque with a new fancy digital torque wrench after it gave ass and it only had 2 were 125ft-lb the rest were 90 to 107. Am I getting these do to the blown headgasket not letting me get the proper torque

[@CUTTERUPROB]

just do a retorque on it at 135 and you should be ok

[@darrinstone49]

Where do you find the parts to converter a older 89 12V VE to Ppump reasonable? It has a ton of miles so thinking of overhauling it at the same time if I can find parts. Do you sell parts? What do you charge to do all the machine work? Any more on doing your side draft intake & porting?

[@CUTTERUPROB]

I am in Calgary Alberta Canada. Best to find a complete ppump engine to pull parts or do a engine swap and sell your engine if it a good running engine.

[@mattleonard5268]

I love my 95 p pump 12v but I think it has a cracked head on the exhaust side. Is that something you’ve seen a lot? I runs good and pulls good and doesn’t smoke or steam or misfire but it makes the coolant pitch black and over pressurizes the coolant so it gets blown out of the overflow tank.

[@CUTTERUPROB]

sounds like the headgasket

[@mattleonard5268]

There is no coolant in the oil or oil in the coolant but the coolant has soot in it

91 and a half was when the inter cooled came out

[@CUTTERUPROB]

I had a 91 built in the 3 month that was intercooled. 91.5 it just stopped being a option. Early 91 just could have been either depending on how it was ordered

[@samwarren7740]

I think I have a head gasket failure near the thermostat like you were saying. It seems to be just leaking externally. I don't see any coolant in my oil or oil in my coolant. Is this something that I can drive for a while or will it get worse quickly? Engine is in an older box truck.

[@CUTTERUPROB]

Never have seen the 12 valve 53 blocks have an issue. Definitely an issue in the 24 valve engines. Completely different block and casting in the 12 valves.

[@CUTTERUPROB]

the later 98-02 12v used the same block as the vp44 24v, i have seen a few of the 12v ones crack but is a bigger issue with the 24v

[@earlkozak6538]

@@CUTTERUPROB I have been able to measure the 12 and 24 valve blocks side by side. The pan rail area for one is thicker in the 12 valves noticeably. With a difference that big i don't see them being the same casting. But if you say they are then so be it. I can't see them being the same blocks myself though...

[@JD-jj6dd]

@@earlkozak6538 are you saying you have compared a 12 valve storm block to a 24 valve storm block and see a difference in the castings between the two? I recently picked up a later production dodge 12 valve that is a storm 53 block and have been slightly concerned about the possibility of it cracking. Didn't realize they came on later 12 valves til I got this one.

Can you make a video on a solid towing fuel mizer low smoke build 300 hp ish.perhaps 750k mile.expectation motor i know thats a lot . What kind of torque does a 300 to 350.make and how would it compete with a later model equal range. Not as quite of course but i think.much better MPG... i have 97 2wd im pulling a 40ft hotshot trailer.

[@davidhylton4305]

@@CUTTERUPROB wow.thanks for the response.. Not everone sees perfomance upgrade measuerd in cubic feet per minute of rolled coal lol. Im super curious how to gain adequate power to pull 15k ppounds say RV and car or in my case 40 ft hotshot trailer. The most efficiently with maximum mpg and max hp with minimal or no smoke. The mpg will be measured at posted speed so assume 65 mph average . Given max mpg as the first priority w hp second. 275 hp to 300 may be the most you can expect w singkle turbo. My 97 w 215 pump and NV4500 gets 17mpg and just got 502 miles on a single fill up. It is however weak as can be. I am changing lift pump and Return check valve this week. Id be happy w 15mpg towing if that is possible. It may require compounds but if thats what it takes ok. Id rather not cuz simplicity for maintenance is also a desire.

[@jimmungai1938]

The P pump will always be able to make more horsepower and torque than the pump one of the advantages of the Ve Years agopump it’s real easy to change your timing you can put on the side of the pump are used to KSP I think that’s what it’s called you can remove that and put an 8th inch timing spacer in there that helps there’s a whole bunch of things you can do the V pump it’ll never make the huge horsepower that all people Apple make but you can get up to 300+ worse contact hungry diesel that guy knows Ve pumps all right you have a good day and cuddle up Rob you’re cool this is six in a rowJim from Kennerdell Pennsylvania Years ago there was a project called rust bucket as a first GEN dodge and they did all kind of things to it and made up to 900 hp with Ve pump and surprisingly he got extremely good fuel mileage
