after 800 miles the oil is over filled by 1 gallon of fuel,325 hp ,64000miles
truck is use, for towing, the load is about 5000lbs. edge, intake, k/n, aurora
3000 turbo, banks exhaust, asi converter/large pan, 35in tires, still has the cat on it.
today complete dionostic, no leaks any where, they dyed and scoped motor and injectors, this was not a dealer. it was a cummins shop, the dealer told me the motor may not be broke in yet !!!!!!!!!! have other cummins the same
no problems!!!!!!!!!! help

 

you have an injector leaking or sticking, or a connector tube backed out. or cp3 shaft seal went out.

 

they dyed the fuel and scoped the injector they are fine, injector pump can not bleed of in to oil,{according to the pump co. and cummins]
connecter tube?????????

 

really, the pump cant get into the oi? hmmmm. lets think about this. doesnt the fit into the rear of the gear train housing and is run off the cam gear? so, if the shaft seal goes, where does the fuel go? into the gear train. how is that gear train lubed? engine oil...........

a connector tube is the tubes that goes through the drivers side of the head, and connect to the injector to send fuel from the rail to the injector.

if they scoped everything, then where is the gallon of #2 coming from?

 

you know more then i do !
i will quote this to the dealer and the cummins shop
$458. to test ,scope and a oil/filter.
your advise prices less!!!!
thank you

 

what a moron. tell you what. you dont want to listen. just keep driving the truck the way it is............

 

If you are making oil then you have a problem, My guess is it is injector related, but as Dodgezilla said poump seal also could be the issue. My 04.5 lost 2, at seperate times, injectors and it rapicly filled the crankcase rather than a little at a time. Whatever the cause find it and get it fixed, Diesel is not a good lube for bearings and such.

 

Not an injector, if it was you would have a scored cylinder, kock/hammer sound, black smoke, etc., you have an pump seal leak.

 

thanks for all your replies!
we are going to ge to the bottom of the problem.
i know that #2 is no good for the motor. but there is no dealer to stand
on warranty,i own 4 other cummins dodge trucks and they are great!
we run them till they have 300000 miles on them and then replace.
thank you for your input
i'll let you know the out come!!

 

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!

 

hey dodgezilla
I said your advise was prices less!
because, dodge said the motor is not broke in yet at 64000 miles and it from towing all the time
the cummins people said the pump could not leak in to the oil.
I own them, drive them, i don't build them.
ounce again thanks for your advise
I will refer your advise to the dealer and cummins!
thanks GINO!!!!!!

 

scoping an injector nozzle and inspecting and injector nozzel can tell you two different things. You can check is to see its mechanical workings with a scope, but you cant see if the copper sealing washers are allowing fuel to bypass from a poor transfer tube connection or if youv'e got a bad injector o-ring. To solve this, I would pull the head and start inspecting injector o-rings and washer seals. These fuel systems are pretty simple when it comes to diagnosing, there really arent that many connections. If it isnt leaking on the outside of the engine, it is most likely leaking on the inside.

 

thanks
for the input
it going to take upper tear down to locate and solve this problem
just is never simple!
know any good dealer or shops for this work, that are reseanable?
thank
