Plan to remove sludge and change seals/gaskets

[ehall]

Interesting thanks. I wonder if he is talking about filling the engine with ATF versus using 10-20%--filling it would certainly beat the crap out of it, which is the stated goal. OTOH he says "wouldn't drive it at all" so I guess he saw real damage from using it too. On the third hand, trannies are nothing but gears and bearings and pure ATF doesn't tear them up... different metals and loads though. I suppose the question is what is worse, blocked passages or scuffed components

Agree, blocked passages and damaged bearings/journals or clean passages and damaged bearings/journals--sort of like that story "The Lady, or the Tiger".

The oil I bought just said "sae 30" I'm going to pick up the same oil (shell rotella) but in 15w40. Should make her a bit more quiet I hope

Also my oil pressure goes anywhere between 20-60 psi

Still kind of loud. Hopefully time with this new oil and rislone will help

I just thought I would mention, based on your photos showing the oil filter, the O-Rings for the filter adapter (both upper and lower) appear to be leaking. I can tell you from experience the oil leaking around those O-Rings will run to the back of the motor and appear to be a rear main seal leaking. For 5 bucks from the stealership you can get the kit and replace those O-Rings pretty easy. I did not get to hear the video, but I also know these 4.0s tend to get a little piston slap when they get up in miles and years. I would be careful how much "flushing" I would do to this engine. Sometimes the sludge is whats holding things together and you can create more leaks and cause bearings to spin. Just my 2 cents.
