I am using oil . I am not burning it or leaking it .seems to do it more on trips. And I just put new seals on the bottom of the injecters .and ther are still leaking .help cummins fresks

 

your using oil, and you put new seals on the bottom of the injectors and their leaking?
I'm not trying to be mean but are you asking two different questions??

 

the seals on the injectors should have been copper O-rings, what other seals did u replace ?

If your engine is using some oil ( like 1 qt every 1K or so ) theres not a real problem, but if your talking about 2 qts every 1K, then you might have a Valve stem issue,

Does it smoke in early mornigns till warmed up ?
What color is the smoke ?
Does it seem to smoke/haze a bit at idle when warm ( at opperating temps) ?

Keep posted and search under truck for leaks, also how much smooke comes out of the oil fill when truck is running cold VS hot ?
