i checked under the turbo i dont see any oil there either also check the tail pipe, it has carbon residue but is dry carbon look like, not wet though, after i replaced the inj o-rings i used 3 full tanks of fuel and i dont see any oil trace on the fuel filter, you think my piston rings are the problem? and if so don't i suppose to loose power? or to see a lot of smoke when the truck is running or when the truck is under load.

in theory if you are blowing a gallon of oil out the tailpipe in 70 miles then there should be oil in the tailpipe or leaking from the connection at the turbo. i would run a compression test to make sure you have good solid numbers, i dont suspect a problem there but you never know. if the compression test come up clean then it might be worth your while to drop a fuel tank and reach inside and see if there is any oil building up. that much oil in that little time has to be goin somewhere and should be easy to spot.

is the truck runing ok? any loss of power?

here's a dumb question but is the air filter clean? if its dirty or plugged up then the motor will suck oil from the drivers valve cover. thats another thing to look at, is the inlet of the turbo full of oil?

I have a k&n filter fairly new and when i did the inj o-rings i removed all the plumbing,at that time i took a look inside the turbo and i didn't see oil in there
what im going to do i will run the truck with out the air filter to see if there is a difference on oil consumption unless you think is unsafe to use the truck without air filter what do you know about the k&n filters? some people don't really like them they say they don't hold dirt very good, Its that true?

definatly dont run without the filter, you will find the general consensus around here is k and n is bad, they let too much dirt by and dust the motor. how large of a filter is it? does it provide enough air? are your turbo fins in good shape?

Pull the fuel return line off from under the truck (quick connects).
Run the truck and let the fuel drain into something that you can see. (bucket ect.) Check for oil.

i have a 6" round By 10" long when i got this truck it came with no filter or filter housing at all, i couldn't find a housing quick enough so i went to the auto parts and that's all i could find i will try to find me the original housing for it,
you think the filter is to small for it?

it may be too small but the new issue i just found out about is the fact that you said the turck came with no air filter on it when you purchased it..... what condition are the turbo fins in? and i thikn a compression test may be the first thing on the list now.

turbo fins are in good shape i look at them they are complete and no visible damage, it spins freely too, how hard is to do a compression test? do I suppose to take it to a dealer or I can do this test at home? i really dont know how to do it, never done it before on a diesel engine i have done it on gas engines before i still have that tool here at home.

you need an adapter that threads into the hole the glow plugs use and then perform the test as you would on a gas motor
