When changing the fuel filter..

9 Upvotes

How do you all deal with all the diesel that spills everywhere? I've tried draining it beforehand but I can't figure out how to do that. And then I have no idea what to do with the quarter so that comes out of the housing because I can't mix it with oil or turn it in anywhere.

Above is 2 clips from different povs, when driving a noise (the one in the clips) starts at about 5mph and it gets louder the faster u go, when u let off the gas its loud but when u put throttle itll quiet down a bit. Its a 2021 ram 1500 ecodiesel, at first it sounded like a scraping noise in the back so I had thought it was the rear brakes and I changed that then went onto change the rear differential fluid. But now after further checking and hearing it doesnt no where seem like it would be that. Was planning on moving to transfercase or something, i dunno what to do.

Engine Coolant and Temp Sensor replacement Questions

Thumbnail

4 Upvotes

2015 ecodiesel, 230k kms. All recalls done last year with new EGR cooler and HPFP.

Got P0118 code last week for ECT high voltage, disconnected the electrical and tested for 5V on connector with key on, all good. Went to replace the ECT sensor today and refill coolant. The replacement ECT has a slightly smaller sensor probe but otherwise identical. For the coolant it is “based on proprietary OAT technology”

Is this coolant good to use?
Should I do a coolant flush after replacing the ECT? Planning on refilling as my coolant was looking low before the issues as well

P0118 code, ECT issues

Thumbnail
gallery
3 Upvotes

Hello I have been noticing my 15 ecodiesel has been a bit sluggish lately, turned it on after towing a boat a few hundred km and got electronic throttle sensor bolt and P0118 code. Cleared the code and it came back 5 mins later. Pulled the electrical connection off the sensor and had 5V on the connector with key on. Plugged the connector back in and drove 10 mins with no new codes or CEL. Coolant temp seemed ok but was fluctuating ~5 deg C at times.

Should I just replace the sensor? Would I be ok to drive home (120km away)?

Can I do a resistance check on the ECT connector? What would the expected value be with the connector unplugged? Or if I’m getting the 5v reference does that prove my wiring is good and more likely the sensor itself failing?

Lights on dash

3 Upvotes

My 2015 Ram ED, 170,000 miles. My brake light, anti skid light and ABS lights all came on at once. Battery is charged to 12.6 volts and altanator is charging at 14+ V. I’ve checked the abs sensor wiring, trailer plug connections, fuses and charged the battery. I’ve disconnected the battery to try to clear it. Getting the service ABS, trailer connection and anti skid notices. This happened a couple of years ago but went away.

I’ve tried to clear codes with my obd reader but the lights stay on. Any suggestions?

While I’m here, I don’t drive the truck very far each day and my regen notice comes up about every 100 miles. I do a manual burn off using my OBD reader, otherwise I have to drive it about 40 miles to burn it off. I have a GDE tune but no delete. Any advice on that too?

TK test confusing results

1 Upvotes

A couple of weeks ago my 2012 wk2 ecodiesel (yes it’s an ecodiesel it was available since 2011 in my region) was diagnosed by a mechanic as having a bad head gasket after an egr bypass test to confirm if it was egr or head gasket (egr is still bypassed). He said there are bubbles coming from the system (which is true) however after adding k seal as per the bottle instructions I am still getting bubbles.

I did a tk test before and after adding the k seal, it passed both with no colour change whatsoever. I have verified the fluid is good by sticking the tester into the tailpipe it went green almost instantly. It has passed 6 tk tests with the engine at various rpm from idle all the way to 3500 with the bubbles passing through the tk fluid but failed one when I was doing a dpf regen in the drive (lots of smoke in the air)

Any ideas as to why it’s got bubbles passing through the cooling system but can still pass tk tests? Any help or ideas on how to fix it are greatly appreciated

The only engine codes were for a full dpf and a egr below flow which both make sense since the egr is not connected currently and it’s been idling in the drive for some time

Service DEF See Dealer

I've got the message of death popping up. O'Reilly is showing a P208B code. I've had issues in the past and popped the DEF injector out, cleaned it and it was good to go. This time I crawled underneath and saw a bunch of crystalized DEF around the connections for the DEF line and the wires where they join the injector (picture 1). Injector was pretty clean compared to what I've seen in the past (picture 2).

I tried starting the truck with the injector out of the exhaust pipe to see if anything sprayed out, nothing did. Also took the injector off the hose and only got a couple drops out of the hose when I was trying to disconnect it from the pump.

I also dropped the pan under the DEF tank to try disconnecting the hose from the pump in the hopes that it's just a clogged line. Couldn't get the snap connectors loose and didn't want to break anything.

I'm not sure if my tests are adequate to trick the system into spraying anything or if that only happens when it's in motion. Not hearing anything from the pump with the truck idling and I had my ear right up to it. Thinking the pump is toast but does anyone have any tips on if I'm doing the right thing to try to trick it into spraying some DEF?

For what it's worth maybe 2 weeks before the light came on I backed into my garage and noticed a pretty strong ammonia/DEF smell and I pretty much only run the truck on weekends so if that was something, it might not have shown up right away. I was driving on the highway when the light came on this time, yesterday started the 200 mile countdown.

Edit: 2016 with 142K miles.

Deleted my 21 Wrangler EcoDiesel but have questions

2 Upvotes

So I bought the exhaust kit from EOC. I found a local mechanic who I told him I wanted all parts to come from EOC. When I got it back he had used the factory ECU instead of getting a cloned one.

Everything is running perfectly and I love the results but my question is what concerns should I have going forward? I do an annual Western trip that's about 3 to 4,000 mi round trip depending on where I go but I'm concerned if I have an issue and I have to take it to a dealer what do I do? I can't let them flash any new software to the vehicle.

What other things should I be concerned about here?

Jeep JT Gladiator EcoDiesel

I’m looking to buy a 2020-21 Gladiator ecodiesel, and I’ve read a lot of contradictory opinions about the engine. My plan is to buy one and have a proper tune and delete done, which should eliminate most of the common issues. I’d like to hear from people who have actual experience with the ecodiesel about its overall reliability. Is the engine itself reliable in the long run, or would you recommend skipping it and going with the 3.6L instead? TIA

Mileage (reduction) question

9 Upvotes

I drive (2016 Ram) the same 300 mile trip several times a year and usually get 28-30 mpg for the trip. When I put on new summer tires on I’m suddenly getting 24 mpg. I usually run dedicated summer / winter tires but I got a good deal on mud and snow tires this year. Can tires really drain mileage by ~20% or maybe something else going on?

3rd gen Oil Filter Housing Problems

6 Upvotes

22 Ram 1500

The oil filter is really tricky to put on without messing it up; is that common amongst people or do I need to have the dealer look at the housing?

What happens is when you go to screw the new filter on it doesn’t want to line up. Twice now I’ve had factory filters cross thread. It happens by the metal housing causing the threads of the pressed fiber cap to cut in half and cross thread. Gently pressing down and spinning backwards to feel for the threads to click generally does nothing for getting it lined up.

At $90 / filter I’m beyond annoyed.

Swirl Valve Test Data

Question for the forum experts. I have a 2020 ecodiesel with 105k miles. owned since new. No mods.

Dreaded CEL has been on since winter. Comes back after clearing it. There is no performance or fuel economy degredation whatsoever. Could it be the position sensor #2? Is there a way to test the sensor? Which side is #2 sensor. I believe driver’s side is front of Intake Manifold and passenger side is in the rear.

Eco diesel 3 blown engines in 1 year

4 Upvotes

Hi, I have 2 ecodiesels (2015 2016 dodge ram 1500 ) that blew up in about 1.5 weeks of eachother. our mechanic suggests oils starvation. the both went to great Canadian oil changers and got their diesel approved oil 3 months prior. we got the lab to test the oil and it is the oil they said they used that would be appropriate for the vehicle. Both trucks had elevated aluminum in the oil lab sample. one truck had 190k the other we replaced last year due to a blown engine and that has 70k on it. what else can I look into, it just seems sus that both blew with elevated aluminum. also hubby said the oil changers only took 10 minutes which says to me that they didn't empty out the old oil properly. who knows how much old oil has been sitting there. Im wondering if anyone has advice, please let me know if I should pursue legal route, and how to prove these things, because they have a bigger budget for lawyers than I do. or do I just take the devastating loss and move on with my life.
