The worst case of sludge I ever saw was a 62 Chrysler 300 convertible 413 cu. in. I bought. You know the old saw about the little old lady that just drove it to church on Sunday? I think this was the case! Long story short, it was so crapped up I had to use a scoop to clean the tappet chamber out! My Dad suggested I use Aeroshell aviation oil designed for radial engines. It's a high detergent ashless dispersant oil in 40W. We had it in drums at the airport where he worked. When I changed it the first time, it came out in CHUNKS! I changed it every 100 miles with a filter 5 times before it was clean!
Then I switched to Valvoline 10W-30 and the rest is history.

I replaced my leaky valve cover gasket soon after buying it in 2013
It was clean and looked good!
I am running mobile 1 5W-30 synthetic/Mopar oil filter

Cruiser, will my oil pressure drop down as the sludge slowly gets removed? I'm not really sure if it the sending unit actually works, but I ordered a new Mopar one that should be here soon. I'm doing all the connections in your tips when the weather clears up now that the Ox-Gard showed up, maybe that will help it read properly too?

Worse than this engine? Holy mother of car Gods! I don't understand how people can let them get like this, although when I was much younger (18-20) I did treat my old 73 Mustang like crap. I was terrible at keeping that engine maintained properly and ended up having a valve break and shatter one of the pistons driving down the highway at 70 mph.

It shouldn't drop at all.
Get the dose of Rotella and MMO in there and drive it.

That's the danger of going the high-detergent route. Those chunks can clog small passages and trash a bearing.
