Leaking oil pan or tranny problem?

[TruckNorris]

Changed my oil and installed a fumoto valve the other day, when I came across this. This sludge is leaking all over the oil pan and transmission. I'm not sure if its from a bad seal on the oil pan or a potentially worse problem with the tranny? Suggestions?

Is yours a early '04 with the '03 motor?? If so also check for your ICP leaking at the sensor or plug.

Its an 04 with the late build motor. My ICP is on the passenger side valve cover

I don't think this is an oil pan or transmission leak. You notice it now because of your recent work installing the Fumoto valve - great choice by the way! Use of a degreaser to clean the "sludge" will help you to pinpoint the source of the leak. Quite possibly this is coolant from the hose connection on the EGR cooler just as well as the ICP as indicated above. This appears to be a small leak now...they don't heal themselves of course but clean the area off, observe and don't forget to have that used oil sampled at a good lab!

I had the oil cooler replaced after I bought the truck, so its a very good possibility that is what it's from. I'll have to clean the area thoroughly, and had already planned on doing a coolant flush this weekend. Hopefully that's all it is.

I recently learned my truck got brand new heads in 07, and I haven't had any problems with the oil cooler/gaskets/temp deltas since I bought it, so I'm hoping that luck continues haha.

I'll have to check those oil labs out. I had also installed a coolant filter a few months ago and was surprised that there was absolutely nothing in the first filter when I tore it apart. Might as well make sure the rest of the system is working properly.

Check your glow plugs they are between valve cover & exhaust manifold.
I'm going to take care of when I change oil cooler.
