Was the oilfilter really clogged?
Did that cause the drop in oilpressure?
Because i don't see how the bad injectors can cause the drop in oilpressure or clogging up the oilfilter.

A answer to those questions would be interesthing.

 

I was going to tell him to expect dpf problems very soon. With bad injectors, the engine would be producing more soot as it wasnt running right, as well his after burns would probably be weak if they were even working at all because his motor would be having trouble getting to the proper Temps for a burn.

 

But no one knows what happend to your oilfiters,right?

 

Bingo.

Get them to do a forced regen and see what the differential pressure numbers are after, should be less than 3 cause all that soot probably built up in your nice new dpf.

 

Not picking a fight here,just want to understand what happend.

BUT why did they not find the soot in the oilsample?

 

I know it can get costly, but if your engine has any age to it, I would have thought about replacing the other 4 injectors and paying for it out of pocket. That way you have all 6 injectors new and fresh, not 2 fresh ones with 4 worn ones. Labor to install them is basically free since they are already there.
