Hello all, I recently change the oil in a 2007 6.0. A day after the oil change the deltas started to separate like never before. 90% of the time the spread previously was 5 to 7. Now I’m getting 10 and 15. Normally the oil temp was rarely above 200 unless towing. Truck is totally stock except for egr. This morning I went to check the oil filter to see if maybe it wasn’t setting correctly allowing oil to bypass the filter and not getting through the cooler. It was installed correctly, but I found it was nasty and gummed up. Truck has everything oem. Filter, cap all Motorcraft. Rotella oil. I was experiencing some stiction which is why I tried the archoil. I did the flush procedure last year and swapped the oil cooler with oem parts. It’s was perfect since then. I’m going to change the oil again and not use the archoil. I’ll check the filter again after a few miles. I’m going to change the oil and filter immediately. I will check it again after driving then check the filter and change the filter again.
Have any of you seen this before?
Looks to me like there's a piece missing on top of the stand pipe.
I have also been using AR9100 with every oil change for many years and have never seen anything like this.
What would cause oil to be leaking out of the head at the exhaust port? Leaky valve stem seal?
I'm guessing the owner added something like oil stop leak or whatever and is now regretting it and blaming it on the Archoil. Doesn't appear to be contaminated with coolant and looks like it's been cooked/burnt to me, but who knows!
Only time we see things like this they are not in running condition.
Oh I don't think that engine will be in running condition for much longer lol. The oil/egr coolers must be clogged to all hell and soon enough an area of the engine will be starved of oil and grenade

You might be onto something, or even HG stop leak.
Towards the end of my HG life, before it let loose, I recall seeing oil residue on one side of the exhaust manifold.
Climbing out on the limb here playing the guessing game. Truck is used with past neglect, when the Archoil was added could it start breaking up sludge that was present?

Just speculating...........
If there was that much sludge in there before I think it would have been evident.

You’re guessing wrong. My buddy is just an older gentlemen that doesn’t work on his vehicles. He has only done pump diesel. I just now got him talked into using fuel treatment to help him keep his truck lasting longer. I do his oil changes and suggested he use the archoil. I realize it’s probably not the archoil. It’s just only the only thing that has been different in the last 3 oil changes. Was just asking if anyone else had seen it. Wasn’t calling anyone’s kid ugly.
I'd send a sample to Blackstone or another oil analyzing site to get it checked before doing anything.
When an ex-co-worker used to be a service manager at our region's largest Chevy dealership, he had an older man come in with an oil problem. He was a woodworker and thought he put oil into his engine; it was linseed oil. He didn't like plastic bottles, so he would put the new motor oil into his old, washed-out gallon steel cans but mixed them up. Labeling would have helped.
Edit - Lol, my spell checker changed Archoil to Amsoil.

Nope. Just Ar6500 in 1 tank and 16oz of AR9100 after the last oil change. The man doesn’t add anything, but diesel. He doesn’t mess around. I’m changing the oil again and sending off a sample to find out what all is in there. Going to flush it again as well. He’s a good dude. Hoping no one dumped stuff in there to mess with him.

Wasn't trying to offend you or anything bro, but does look like someone put something in the oil.....to what end though?
It's just very odd as we've never seen anything like this before and Archoil friction modifier has been used for over a decade now and no reports like this that i can find so again very odd. Rotella has a good amount of detergents so if there was a bunch of sludge in the engine you for SURE would have seen something in the OCI's you've done so the Archoil breaking up the gunk just doesn't seem logical.
