Yesterday while checking my oil level I noticed what looked and felt like oil where the valve cover meets the rest of the motor. As far as I can tell, it doesn't look like it happened overnight, but mabey over 2 weeks since I popped the hood last.

Is this normal, remember I'm a newbie. On a gas vehicle this wood be considered bad, right?

Thanks for any input on this.

Oil leaks are not acceptable to any engine except Detroits

 

Anybody else?????

 

No leak is normal and being that they are sometimes hard to determine where they are coming from I would take it back to the dealer and have them make note of it. Its under warrenty.

 

Thanks I will.

Took'er by the dealer today, diesel mechanic said it was more like seeping than a "leak". He put a dye in the oil and said to bring it back in a couple of weeks. I asked him the point of the dye and he told me under black light you can see a yellow glow if it's leaking (seeping). He said the dye test has to be positive in order to justify warranty work and to order the parts from cummins. So even though the mechanic saw the oil "seepage" all the way around the valve cover.. he's still not going to do anything until there is a yellow glow under black light.

anyone care to ease my mind on this or should I have spent all my money on becoming a lawyer!!!!!!!

 

If you do a search on "oil leak" in this forum, you'll see a couple of people have had the same problem. In most cases the gasket was not seated correctly when they installed the cylinder head cover. There is a rubber reuseable gasket that fits in a groove on the cylinder head cover(aka valve cover). It may have been pinched or not torqued correctly when it was installed.

Notes from FSM:
