I was looking in the engine compartment and found
oily looking stuff on top of my intake, not sure if it is
oil that i spilled while changing oil or if is diesel fuel.
Tried to wipe it with a shop rag and what i got was
like it has been there a while. Does not have much
of a smell to it at all. It cranks good, runs good and idles
good. Never any problems with 53,900 miles on it..
See pics. although there are not that good, taken
with a camer phone.
Anyone think it may be a problem??

 

All I see is a minor oil leak from the valve cover. Clean the area well with brake clean and keep an eye on it.
