new 2003 oil leaking

[CATCRACKER]

i need help tommorow i am bringing it in for service i need your guys opinion. between the aluminum valve cover and the top of the head on the exhaust manifold side there is oil leaking out. it leaking only on this side and it leaks very slowly.



What do you guys think is wrong?



Keep in mind this truck has 10,000 miles on it max boost i see is 21. 75 and cruising on the interstate no load @75mph i see 700egt. max egt stock i can get it to 1300 seems high for stock no load. Truck has a funny idle when cold.



I added this additional info b/c i thought it might help diagnose the problem



Could this just be a gasket?, If so why would it fail so soon? Is this a sighn that somthing esle is wrong? Possibly a bad deck machining job on the top of the head? I am really ****** of about this so please help.

Have you tried torquing to spec. ?

If you remove your vanity cover, then your valve cover.

You will be able to see the 7 bolts that hold your rocker/wire housing down.

These bolts torque to 24nm, they are 10mm headed bolts.



The gasket could be pinched or binded and leaking.



I seriously doubt your head is not machined perfectly.

The only other thing I can think of is that you have too much blowby causing a seal failure (which I doubt).

it starts leaking from the front all the way to the back it is not confined to one area. excessive blow by might be the answer! what you that mean bad block? ring failure?



the leaking is not confined to one area.



anyone else seen this failure?





the mighty cummins..... hmmmmmm might have to rethink this one



all will tell monday





may have to go back to gasser since i would not by a furd or chevy. or wait awhile for them to get the kinks out of the all new truck.



DC is being sued by a guy in Baton Rouge b/c he was pulling a car trailer when the rear axle locked up causing a major accident. i hope he gets millions. DC better hope i am not on that jury

I really doubt your blow-by is excessive.

And I do not think you have a bad block.



Most likely its a seal failure of some sort, or a cut in the seal and the oil is running all the way along the seal.

i would say yes it is a leak and it is running towards the back of the motor except that on several spots it is dry no oil.
