Injectors causing blowby?
Truck went into the dealership today and before it went in I was told I had the #5 cylinder down on compression. So going in I thought this was my blow by problem but today they didn't say anything about the low compression they told me I have 3 bad injectors, I think it was 2,4,and 6. Now I don't know what to think. Any suggestions?

The oil intake works out to be about a quart every 500 miles or so. It still is on warranty but with mods its been taking some convincing to get them to use it.

I have a freind with the same kind of problem, smokes blue, uses enough oil, runs really quite and smooth, he installed a new turbo but it did not change anything. Can these engines be worked on in frame, it is an 03 with 4x4.

I talked to the dealer again today and they said there was no loss of compression it was or is the (my mistake earlier I thought just 3) 4 injectors that are bad. He said he replace the injectors on warranty if I paid the labor. Any guess on how long it should take? Thanks

Well it's amazing what can happen in a day. After they tell me I have 4 injectors gone I asked them to check the 1 thing I asked to check in the first place (the #5 cylinder). I get a coffee time phone call asking if they can pull the motor. shot. I guess that scanner doesn't tell you everything. 2nd time that cylinder has gone. Bad luck I'm having.

So you've had this motor rebuilt before("second time #5 went bad")? After having my motor rebuilt took it to get the injectors checked and at first they said #5 injector was dead, so they replaced it then said that it had a loss of compression in #5 cylinder. So took it back to where I got the rebuild and come to find out cummins had givin us the wrong head gasket, replaced gasket and went ahead and replaced rings on #5 and fixed problem(wasn't burning oil though, just slowly lose power). Still ended up having to replace all six injectors anyway though from a prior problem.
