How much you want to bet this is related to Amsoil having better than 3,000 mg of calcium in it?? Which is more than the typical 2,000 mg found in almost of the other oils out there. And Mobil 1 which uses calcium and magnesium totally about 2,000 mg. That's where this comes from I bet. Granted.... This is before Dexos gen 2 came into being. Now, that has changed even Amsoil with their formulation.
Cleaning oils, who's best?

It’s ppm not mg
That Caddy looks like a challenge for a cleaner
Guess I'd glop out what I could, and then go after it with 50/50 MMO and HDEO for 1,000 miles at a whack ... Prolly change the filter every 100 miles for a while ...

That was a few years ago. Took maybe 12 hours with paper towels, tweezers and qtips to clean it up. It ran perfectly fine before that but was getting a CEL for the timing chain. Car was under warranty but when they took the covers off and found this, they said no coverage.

Yuck! Any idea what oil was used in that and how often it was changed?
No, and not very often.
Too bad, that would be great to know.
BTW, you did a great job cleaning that up with the items you mentioned! I would have bet you were going to mention a putty knife was also used!

atikovi -- When an engine is sludged up that bad, is the oil on the dipstick black?
Not if it's been changed in last 1000 miles, it's not a diesel.
What if it hasn't been changed in the last 1000 miles? I'm thinking if the sludge is black, then the oil on the dipstick should be black also.

Not always. Back when 1MZ-FE engine sludge was all the rage, one of the indicators was that the oil stayed clean looking despite the condition of the engine.

Depends on the car as well. Toyotas are hard on their oil, my parent's Sienna almost always saw M1 and PP, and when I pulled the valve covers to check the valves and install new gaskets the valvetrain had the usual varnish on it but it was in pristine shape for a 100K+ motor. My parents also had a Nissan Quest we tried hard to kill, it saw Red Line for most of its life(I got a good deal on the stuff) with some Castrol, M1, PYB and Chevron Supreme as well. When I did the valve covers at the 180K mark, it was clean.
I'm curious about that Cummins/Valvoline Premium Blue Restore myself.

If that was the case it would indicate the oil was dissolving the sludge, but then, there wouldn't be that much sludge in the first place.

The engine you have pictured; what did the oil look like on the dipstick before you cleaned it?

Looked fairly clean.

It's designed specifically to clean heavy carbon from the ring packs in Cummins ISX engines.
Hideously expensive, largely because it has more ester content than pretty much any oil you can buy. Has to be purchased through a Cummins distributor; it's normally sold as a service event rather than an oil per se, but apparently Cummins distributors will sell it.
Hard to imagine there's anything out there that'll be as effective.
Yes, it's $73.00 a gallon at Cummins in Albuquerque!
Respectfully,
Pajero!
