Found this in my pan during oil change

I don't want my picture taken.

 

Good plan! I was starting to worry we didn't hear anything from you.

 

What would trucking be with out a little added stresssssssssssssssssssss!!!!!!!!!!!!!!

 

How many Oil changes have you done since your inframe??

I reckon It got in your Oil pan whilst your Inframe was being done, & whoever put it back on was a little hasty/careless & didn't properly check it before reinstalling..

I say this because that's exactly what happened to Me many years ago. With a CAT Motor that had had a recent bearing Roll..

 

I would be more concerned about the valve adjustment you said just had done.

 

Here is a picture under valve cover. The nuts that hold the VVA on are course thread and the nut for the valve adjusters are fine.

This is the truck I have in the shop where the adjustment nut came off and then the bridge turned sideways and bent two valves.

 

There is only one place a nut like that will come from on a cat. The hold down nuts for the vva's and or jake housings. No where else in a cat engine do they use that Style nut, NO WHERE! yes that could of migrated to the pan from the top. Pull valve covers and eyeball the studs to see if any nuts are missing. Also look at the adjusting nuts for valve train and jake to see if any are missing. If not then just ride driver, just ride!

 

I agree with Ristow. Stop at a dealer and compare.

 

Hurst has a bigger nut than in the photo.
