I started having an oil leak under my truck in the last week or so and when I went under the rig briefly (it is raining here) it looks like it may be either coming from the oil pan itself or the seam between the tranny and engine case.

I thought I'd try the easy solution by torquing the appropriate bolts. Does anyone have the torque specs for these two sets of bolts or have any other suggestion where the oil could be coming from?
I have ~130K on the truck.

Thanks!

 

Are you sure it's not actually from the top of the engine? Just to rule that out.

It was raining today so I didn't have a good chance to look around.
Why are you thinking it might come from the top of the engine?

 

These trucks have a tendency with a leak up top to drain back and it appear to be from the oil pan or rear main. Rear main very rarely leaks and if you think about it thetr are alot of seals up top. Case in point when I took everything off of the top of my motor the galley had 1/8 inch of oil and goop and oil all over the same places as yours. I ended up having zero leaks but the 11 years of oil changes (oil from the oil filter) seems to be where it came from. Just a thought though it could very well be the oil pan or even from the rear cover bit it's usually from the oil filter housing, turbo feed or drain, icp or ipr from what I've gathered.

Could also be the bed plate. It's between the block and the oil pan and would require pulling the motor to fix. Clean it up and then watch it.

 

Just thought I'd bring this thread to a close for anyone down the road.

I cleaned the motor both on top and underneath and then put a large piece of paper under the engine. As it turns out the Fumoto Valve I have is apparently leaking...and I don't have my old drain plug so I'll have to buy another Fumoto valve (they are very convenient) or just get a regular plug...

 

This is the first instance I've heard of a Fumoto leaking.

 

Yep
I check mine frequently just because.
Glad op found it and an easy fix.

When I did my last oil change I probably didn't get the oil warm enough to suspend all the particles that may have been in the pan. I left the Fumoto valve drain for quite some time as I was doing something else in the garage at the same time.

My hypothesis is that some "sludge" that contained some particulate matter prevented the valve from closing completely. I drained out a cup of oil this am hoping to flush any comtaminant from the valve. We'll see if I get any dripping tonight....

 

Curious to see if that did the trick.
