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?

 

Archoil "what"?

They make/sell multiple products. Which one did you use?

 

NEVER and I have used Archoil 9100 religiously for 7+ years

Almost looks like the EGR recirculation soot from your intake. You mention the EGR is different but have you rerouted the CCV out or the equation, or still blowing into your intake?

I don't have it anymore but I recall the inside of my intake looking the same.


I should have mentioned, I use the large truck spin on filter provided by BPD for the air to oil kit I run. Regardless, with that much $h*7 in your engine, I am sure I'd see remnants if that was going on in mine.

Good luck

 

Unless whatever that stuff is will dissolve that engine is hosed. Every orifice in the motor will be plugged I would think.

 

Where did you get the Archoil from?

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.

 

Forgot to add that it was AR9100

 

You mentioned the CCV reroute. It’s actually my friend truck and I’m helping him figure it out. The CCV reroute was never done and I’ve seen oil leak coming from the driver exhaust manifold. What’s the best CCV reroute method for the 6.0?

 

There are a few ways. One way is to route it to the atmosphere behind the cab, or reroute to a truck style filter

I have it setup using the racor as pictured and have for years. Just recently I routed it to atmosphere because one of my hoses needed replacing and I got lazy.

I capped off the inlet at the intake elbow and went with it. I heard stories of foul smell, oil residue all over the place blah blah.....Not one of those claims yielded truth....take it for what its worth.

You'd be astonished to see the buildup in your intake from that $hi7

 

I've done 8 oil changes over the last 30,000kms and 3 of those used Archoil friction modifier and 2 with Hotshot stiction eliminator and my oil and filters have always looked super clean so I HIGHLY doubt a couple ounces of AR9100 caused that! Oil looks like it has 100,000kms on it so I dunno, but looks like a tear down is in your near future

 

Good point.

Now that I reread the post and realized it is NOT your truck, how long did this go between oil changes?

 

Curious why you did the ccv delete?

 

I've ran Achoil 9100 a few times and never had issues.

I watch a Youtube Channel of a guy that tears down wrecked motors and this looks what he finds when someone runs very extended oil change intervals. I would hate to see the rest of the motor, it can't be pretty.

 

Yeah - wow...that's nasty!

I'm also a religious user of Archoil 9100 and have NEVER seen anything like that. My truck currently has 188K on the clock.

Just a SWAG, but my guess is that the truck had been abused with long oil chance intervals and low maintenance and the insides had tons of buildup in there. The archoil circulating through the system just helped to loosen that stuff up...

"Forgot" to add it was Ar9100, LOL

The only real detail you gave us is that it is nasty and gummed up. Pictures are good, but they can not communicate what words can ....

Describe the solids .............

• sludge?
• sticky?
• all soft clumps?
• sludge containing particles?
• if contains particles, are they magnetic?

Then, you should probably keep enough of it to see what might dissolve the "material". Maybe try diesel fuel first.

 

I just help him with general maintenance. The last 3 were done after 3000 miles. I just changed the oil prior to discovering this less than 75 miles ago. He mentioned the delta separation grew since the last oil change 75 miles ago. The only thing I changed was putting in the Archoil 9100. I noticed oil leaking out of the drivers side manifold and checked for oil in the turbo. I then noticed oil built up in the factory ccv box mounting to the drivers valve cover.
