blown isx

You took in a running truck for service.
A mechanic mistreated it.
Now it doesn't run.

I'm thinking they should be fixing it and quick because you are loosing money.

Unless the truck was tore up first, how far did you run it with water in the oil?
How much water?
Did they check the bearings before dyno?
Did you refuse to have the bearings checked?
Did they recommend it?
Does it have a broken piston or did a bearing go out?

At this point they need to prove that the damage was pre-existing to charge you for repairs. The mechanic may have made more than one mistake.
Was the dyno deal a look and see thing?
Did the turbo damage cause enough oil to hydraulic the motor?
Was the CAC cleaned properly before running the motor? (did motor hydraulic on cleaning solution)
If the damage was pre-existing why would they put it on the dyno and finish it?

Is this a shop you have a relationship with or are you passing through?
Does the shop have a good rep?

 

thats sucks to hear about your bad luck, in my opinion it should have had a new turbo put on instead of trying to see if it wwould have dries up, if the seals started pushing oil into the cac system then the seals are blown-theres no saving them, if they are thing that the motor got hydro locked due to the engine oil then it would have had to push some serious oil throught the turbo and into the intake, which would leave me to beleive that there might be bearing damage due to low oil level. keep us posted please i would love top hear more about this and see what they find is the "root cause".

 

which bearing spun 3,4 rod bearing?

 

I'v heard that you have to be extremly carefull when you remove or replace an oil cooler on an isx so that dirt doest get in there or you will have a major failure like a spun bearing

 

glad they found the problem and are doing the right thing, not a lot of shop around that will be honest and "do the right thing".

 

I'm guessing that the bearing damage is a result of the piston damage which is a result of the motor hydrolocking. There is a good chance there is damage to more than one cylinder.

I wonder if the mechanic still has a job?

Drug a dead bus into the Cat dealer yesterday and while I was dropping it I noticed (because of this thread) that all of the trucks that were being worked on had covers over all intake holes, even the outlet of the air filters! Plastic corks or paper towels hose clamped over the openings.
