Freightliner FLD120 3406e Cat issues

We have a 99 freightliner fld120 with a 3406e cat. We are stumped and getting no answers! Need some advice please. A couple of months ago turbo went out so went through Cat and got a turbo. Us, plus a diesel mechanic friend of ours switched out turbos with no problems. Went to Cat to return core and they told us they gave us the wrong turbo, after we drove 700 miles with the turbo they gave us. Their mechanic changed it, outside. Believe turbo was too big. A week later we noticed she blew a little white smoke when started but went away. Wasn’t cold out. Found an oil leak so took her in to get it looked at as well as white smoke smelling like diesel, noticed a rough idle and poor fuel mileage, plus a couple of minor things. Mechanic right away said cracked head. One other guy looked at it and said just injector wide open. Took it to freightliner and they said injector #4 dead. They swapped #3 and #4 and said it was still the same. #4 dead and can hear some air leaking. Due to financial reasons, we told them to hold off and we would pick it up to decide what to do. Get there and there’s 8-10 gal of antifreeze underneath the truck and the truck cranks and cranks, but will not fire!!! Checked batteries and charged them, etc. freightliner claims nothing they did would cause it. We took it there running and now we can’t get it out of parking lot. Any thoughts?! Thank you!

 

Right, I understand. Just didn’t know if anything we are missing could be picked out by someone reading that maybe had some additional advice or something to look at for why it’s not starting at all.

 

Yes, we were definitely thinking about the antifreeze problem keeping it from starting. Just concerned right away when it wouldn’t start and that baby never has a problem starting. Going to try filling it with antifreeze and giving it a try! Thanks everyone
