No compression in Cylinders 4, 5 and 6 Help

Hey Guys,

This is my first post hope I'm not breaking any etiquette.

My batteries died and only way to start my truck up 2019 Freightliner Cascadia DD15 was by using some starter fluid.

Took my truck to dealership and they said I need 8 new batteries. I said fine, my truck has an EPU

They ran a compression test and said that I have major problems. Please see picture of compression test.

1 month ago I had my valve adjusted...this is added information.

My truck drives fine, I don't see the loss of power. I haven't seen if it needs ether to start up since I just got the batteries.

I'm in New Mexico and my leased onto company is in Chicago. My company said bring it in ASAP and we will figure it out.

Any advice would be helpful.

 

0% you would notice. Need to verify doing a manual compression test not a relative. Was this performed before the new batteries were installed? Bad batteries can throw off a relative compression test since it uses cranking speed differences.

 

I don't know if it was done before or after. It was done same day

 

From the times posted on the test, it was done after the new batteries were installed. Here's another picture of the dealer report

 

It would be smoking like crazy if half the cylinders were zero compression. Dpf would plug instantly as well. Unless ether damaged it I would definitely test drive it before doing a rebuild.

 

Thank you Magoo1968. I will monitor it and see if anything changes. I'm trying to get an oversized load from Utah to Arkansas then I plan on deadheading to Chicago for closure

 

Throw it on a Dyno

 

I will be doing it all. I just need confirmation that I can go a few thousand miles without issues. Even if that means keeping my truck running until I get to my mechanic shop. No smoke except this morning when I jumped the truck and used starter fluid. Runs good.

 

To have the rear 3 cylinders be dead like that back in the day one would think it be either a broke cam or broke crank, but i guess a computer could technically keep something that broke running nowadays. 3 dead with half the cylinders dead that engine should be shaking that truck apart at idle and fighting to keep itself running even if you manage to get it started. One would think anyway.
