Plugged SCR and DPF RAM 3500 Cummins cheap fix

- My 2015 ram 3500 Cummins 350000 miles. I experienced extreme power loss. I I diagnosed my DPF codes by 1st changing field filters, waste of time . I then continued to diagnose a plugged SCR would showed no visual problems and also to a pluged DPF. I then found a take off pair on eBay with 6000 miles from a trustworthy seller that I was able to adapt to my Mega cab truck. I wanted to stay with the emissions on the exhaust because I expect it to be something to be inspected at some point and I also understand there is very little mpg gains with a deleted system. My truck had the original SCR replaced under warranty recall at approximately 170,000 miles. This makes me think their life may be limited to that number. If you own a RAM please please use FLUID FILM rust inhibitor. They are terrible from mexico and this product will keep them the grest truck they are.
If your 6.7 ram is loosing a bit of coolant and is starting to have emissions codes, your EGR cooler is probably failing. Replacing the DPF and not replacing a leaking cooler will result in replacing the DPF again, along with a few sensors.
Oil analysis will tell you about fuel dilution and coolant leaks. Blackstone labs is a good one. 58 USD with TBN. New temp probes too.
Good video, thanks for showing this! I'm here seeing the inevitable problems I'm in for at a future date.
I believe part of the problem is the Turbo actuator sticking. The DPF also can be cleaned if it's not damaged.
Don't put stainless bolts into stainless. Unless you make sure to use some kind of antiseize. Best to just use reg steel bolts.
Haha thats a no win situation. Do we fear galling of stainless or rust the most? Thanks for watching.
I put a little stronger bolts and put some antiseize.
KROIL WORKS
Should have just bypassed it. Never have that issue again.
I understand but with the environment today living in the northeast I'm going to comply and stay stock.
How did you bypass it?
Heat the bolts up with a torch once bolt turns spray wd 40 will come right out.
In my explanation I say the ash goes out the exhaust. I understand that it burns and the particles that do not turn to gases are left in the DPF.
Those chunks are the actual filter 😮
Yes, and I learned it truly is a filter. Nothing is to pass thru it until the soot ash is burned away. But eventually they fail, become plugged, as not all products of combustion get burned away no matter what anyone tells you. This is why commercial trucks get their filters cleaned. Small trucks, they expect us to throw them in the trash and ante up for a new one only from the OEM.
FYI. There is a spring right inside of where you “heated” it.
That spring is most likely toast.
Thanks for the information. Can you give more details? Spring inside the flange? Do you mean inside the DEF injector? I replaced one with my old one. The entire reason I acquired the exhaust was the DEF injector failed so the guy deleted because he didn't want to goto the dealer as he was a self employed carpenter. Parts of the exhaust can see awful high heat.
I have a dodge ram pickup same problems from what I see dodge has the most problem of all the pickups and they have recall on these pickups but they don't get the problem fixed tks
I bought this instead of a Ford because it's easier to work on. Almost 400,000 miles for me. I think most of my exhaust problems actually came from a sticky actuator in my turbo.
Goto 18:30 for comparison of megacab and crew cab SCR. (DPF are identical)
I let truck idle spray it wd40 while hot loose up right away dipp it on hot water let it clean and with toothbrush clean it got rid of the 5mph service see dealer
Delete that crap off your truck and you'll never have to worry about it again.
I know but this deal was cheaper than a delete setup. I fear that NYS will force inspections too. I do get up to 19 mpg traveling down the highway so its no all bad....
@@spudth FYI, you can remove the exhaust and DEF stuff (save it in case you need it later), then delete your truck with a tune (EzLynk) and straight pipe it. Your truck still has all the stuff under the hood, but it would be programmed not to use it. If you needed all of it again, it gets flashed back to stock. Works like a charm and is better for our trucks and the environment!! 😎👍
@@spudth I live in NY, there is emissions intact tuning that leaves the dpf working but eliminates the def and egr, better for truck but still clean for nystate
PB blaster not wd40. Use anti seize on the new one
WD 40 is NOT penetrating oil......
Yes it is. Sorry to break your heart. All oil is basically penetrating oil. Some have a smaller hydrocarbon molecule that penetrates better. WD-40 is also not a medication but Dad used to use it effectively to kill ringworm on cows.
That’s not a cheap “fix” you just bought 1 off ebay end of video
The cheap fix was a few hundred off ebay vs thousands at the stealership. Also, I was able to use one from a different chassis.
Why didnt you power wash thr dpf filter
I tried to. It seemed the real problem was a restricted catalytic converter. I'm not sure washing these pickup truck pieces is as easy as washing one in a truck. I'm wondering if I got some bad fuel?
Does power washing the DPF really work?
@@rdp2370 You have to be careful and use chemicals. The DPF is truly a filter. Ash stays in there forever. Large trucks have them cleaned. Ram and cummins decided the pickups don't need serviceable units. The ash is removed with chemicals and washing. There's a good series from and English guy doing his diesel car DPF.
What kind of DEF have you been using at this point?
I either buy def at Walmart or at a truck stop from a bulk tank.
I bought the truck with 330,000 miles. All highway miles.
This is EPAs' idea of dictatorship... at least u didn't delete it.. ud b fined
Delete it.
Any chance you can re-edit this video and get to fuc** point? Good God!
I know, right. I'm in your shoes when I watch it too!
I like to revisit my videos for ways to improve them. This remains my favorite comment. 😍 shut up and just show it done!
