Derate to 5mph crisis - regen not clearing codes for some reason

change injectors at 800k. At 900k change the fuel pump and air compressor. the turbo will go 1m m. Between 750k-850k m oil cooler's o rings start leaking and oil goes into coolant. All DD15 have this issue. Find time to replace o-rings. Also around 850k m breather starts leaking.

 

you were lucky they did not do parked regen. They would suggest you to change def injector or nox sensors ))))

 

look at here. what a price tag.

Did you change the injectors yourself? I’m guessing you changed all of them?

My air compressor is leaking oil, and I’m thinking about just replacing the entire air compressor and not just the seals. My truck mileage is close to 800k.

 

I have changed injectors, fuel pump, air compressor on my truck myself. Changing injectors is easy but DL needed to enter injector codes. Changing fuel pump and air compressor is complicated but I can help you if you want to do it yourself. Put new air compressor and fuel pump if you have 800k on truck.

 

Thank you. It seems like I will need some special tool to set the timing mark?

 

you will need a timing pin. It's $65 on ebay.

 

Can you show me how the timing tool looks? I have a DD15 engine. I’ve never used such a tool. Is it to rotate a metal wheel to a particular spot? What’s the purpose behind it?

It looks like I’ll need a timing pin and also a barring tool?

 

it's not a timing tool it's a set for valve adjustment tools the part is called engine barring tool. there is a window on gear case housing. it must be installed there with two bolts. by using 3/4 drive ratchet you turn flywheel until engine is on tdc. You can turn the engine by big flat screwdriver too but it will be slow.
What you want to do ? valve adjustment ?

look at this video he has OM tools
