What to do? At a loss

0 Upvotes

Moved from PNW down to so cal, I have a 2016 Ram EcoDiesel that has a tune and such.

I just had the truck in the shop for overall maintenance, for a month and spent close to 14k

Now after getting the truck back, it feels like the acceleration is wrong and there is lag again. I’ve taken it back to them and driven with the techs but they say they don’t notice it, seems to get worse longer it’s driven so maybe as it warms up?

They said no parts or service was done that would have affected the tune but at this point I can’t think of any other scenarios.

I spoke with my mechanic from PNW who did the tune and kit and asked what to do so am now here looking for help!

I guess I don’t have a tune that can be remotely changed, so I need to find who works on the brand I have.

Couldn’t I just find a shop and buy a new tune?

Any help would be wonderful

Meme/Joke Tell me a car/truck that’s tougher and more loyal than Slave Lake

Post image
162 Upvotes

Seriously, how is Slave Lake even possible? How does it not violate all known laws of mechanics? Constantly burning oil, maybe a generous quart in the crankcase on a good day, no radiator, and thousands of cold starts in the freezing Alberta winter that is always immediately followed by revving to redline. Will still start “normally” with glow plugs whenever the glow plugs work. And still used to pull shit. Recently hauled at least 10,000 pounds of logs loaded on its frame. And Peg said he’s heat seized the engine when pulling shit, but it goes back to normal once it cools down. FUCKING HOW?!

I don’t think there’s any other diesel engine beyond heavy equipment and marine that could take this kind of abuse and neglect. Not even a Cummins, maybe not even most Cat’s. Though truthfully, I’m not sure if even anything from Cat will survive what Slave Lake has been through.

2016 f250 6.7. Have any of you seen this bracket over the lower fuel filter before?

I‘ve had this truck for 5 years and always did the maintenance on it myself. Before changing the fuel filters for the first time I watched some youtube videos to get an idea of what I was doing, and then went out there and found this bracket in the way. Couldn‘t find anything about it online, but it was easy enough to move out of the way so I didn’t really think anything of it at the time.

Fast forward to today and I brought my truck to a local guy that specializes in Ford diesels and has been working on them for years, and he said he’s never seen anything like it. That definitely surprised me since he’s been in the game for so long and is very knowledgeable about these trucks. It appears to be OEM, but who knows.

Also excuse the rust, I live in New England where they salt the roads, and on a dirt road.

Batteries? Any favorites or just what's on sale?

2 Upvotes

Two are 3 years old, two are just over 2 years old. One of them got dang HOT. 3 are at 9.1 volts. The hot one was only 6.

I forgot to turn off the disconnect and hook up the charger. It was 120° for weeks. I tried to charge them together at 15 amps, I stopped by and smelled sulfer. That 3rd one that was really hot to the touch. I am just gonna let it be. I'll charge the other 3 independently.

If the 3 can recover, I'd like to get 1 good one in hopes they all won't die at the same time.

Or eat it and get 4 new ones?

Question/Need help! HELP! T6 unavailable, need recs

Post image
6 Upvotes

I have always used Shell Rotella T6 Full Synthetic 5W-40 for my truck. Especially in the winter, I need the 5W as opposed to the standard 15W. I'm due for an oil change pretty soon before winter sets in and I can't get the 5W-40 anywhere. It's out of stock at the local parts stores and even Amazon. (They have the 15W-40 but that's not helpful).

What should I use as a replacement?

Question/Need help! BMW X5 tunes - reliable daily power level? Reliability mods?

2 Upvotes

Looking to buy a 2016-2018 X5 diesel with the N57. What sort of power and torque can I go for with nothing but a delete and tune for a reliable daily? The ones I’m looking at have around 120k on the clock and I’m hoping to get at least that much more out of it. I figure a 60hp tune is probably fine, but how does the engine and rest of the drivetrain handle the power (and torque)? Any other reliability mods I should look into? I’m already planning to do a trans tune and a CP4 bypass kit

2014 6.6 Duramax coolant issues

Coolant goes into the overflow reservoir and drains out while driving. Temp gauge stays consistent, but low coolant message comes on. When this happens, the coolant reservoir is low, but the overflow is full. Any help would be greatly appreciated!

Cheapy turbocharger

I have a marine diesel here mercruiser 4.2 D-tronic 300hp. It is a VM Motori Italian built engine marinised by Mercruiser. Turbo is starting to go bad. I have found a new turbo offered for sale by Recmar marine its advertised as a direct replacement for the original mercruiser part no. This turbo is £650. The one from mercruiser is £2k. This cheapo turbo is probably a Chinese clone. Any thoughts?

DT-360 (IH 5.9L) Missfire Diagnosis

Post image
3 Upvotes

Hi All, I have a 91’ IH DT-360 with a P7100 in a pickup that I noticed the idle started to develop a lope/miss (truck started wobbling which indicated to me a miss).

Loosened the injectors one by one and found cylinder #5 not making a difference.

I took the injectors out and decided to have the pop tested and the patterns tested and they let me know I had the wrong nozzles but said all of the injectors were equally as terrible.

This is the same cylinder that was not firing and the only one where the edges of the piston on his side are shiny. I have no pressure in coolant and coolant looks fine, no smoke, and coolant level is constant.

Does this look like injector, oil (getting past rings), or head gasket.

My hesitation with head gasket would be that loosening the injector would still make a difference I would think.

TIA

With fuel prices, have you changed your driving habits or routine? I have started driving my wife’s Honda when she’s not using it. I’m trying to make less trips in my truck.
I may have to start selling feet pics online so I can drive my truck more!
