Nope. Bought the car wrecked. Kinda rebuilt the car... multiple times.
That’s a nasty amount of gook.
I took the bottom off mine after I bought it at 83k miles. Tiny amount of sludge along with the alum seal from an oil bottle.
Ive seen sludge like that in LS engines with the Castek heads that had very slow coolant leaks around the head bolts. Makes a thick dark gray sludge
I didn't see any coolant lost but I haven't put that many miles when I put in the cam and springs. None of the combustion chambers were clean like it ate coolant, at least not on the right side. I gotta remove the spark plugs on the other side and use my scope to see if anything looks clean. In any case I power washed the oil pan and then powder coated it. I then did a quick lapping on the head surface as well as the oil pan matting surface with sand paper on glass. Threw the lifters in the new oil I bought and will fish them out tomorrow and try to put them in. The lower oil pan gasket didn't arrive yet.
Got around to removing the spark plugs on the drivers side and stuck my camera in to see any signs of coolant. This side has a lot cleaner looking spark plugs but with a bit of red coloring on it, which might suggest I've tuned it too lean. One of the things I was going to do was put in a wide band sensor for this reason. The spark plugs on the passenger side were entirely black, like it was running too rich. With that bad lifter I wonder if exhaust gasses were making their way back into the intake? I think the valve that wasn't opening was exhaust? It's the 4th from the rear.
Did my best to take photos of the combustion chamber. Wanna see what people here think.

Actually red is good proper fuel mixture. lean is white
Yeah, if you are running fuel additives. I have never seen a red electrodes on anything but motors running fuel additives, and a red color is not indicative of a normal/good fuel mixture.

That's just 93 octane gasoline. I'll get around to taking a photo of the other spark plugs. Before this happened the Vette would start up smelling like it ran rich but eventually it wouldn't. I did tune it based on the O2 sensors on the car.

So no octane boost? No Sta-bil during the winter time?

Well if he's looking if the spark plug was his problem i don't think so. And yes additives will show red but thats still doent mean its bad.
Sorry I haven't gotten the photos of the other spark plugs, because I did clean them. I was able to put the engine together and get it running. With 5w-30 oil the pressure is 40 when it warms up, just like with 20w-50 that I had before. I spun the engine for a minute with no spark to get oil pressure through the system. It did make a ticking noise when it started but quieted down once it warmed up. Don't know if it was a lack of oil through the system or the infamous piston slap? I think it sounds good but I'd like to hear what others think. I'll record another video with the engine cold to see if it makes the same noise. Also the smoke is me having the EGR gasket sitting in oil for a while.
I think it sounds better than before. The phone I used to record this is a Pixel 6 Pro where before it was Moto G7 Plus. Looking over my older videos of the noise it does sound normal now. There are a few concerns before I consider this good. One is that a single head bolt didn't turn 90 degrees a second time. The very back right bolt that sits bellow the exhaust header. I torqued it to 22 foot lbs and then did one single 90 degree turn but couldn't do it a second time. I feel that if I did it a second time it'll snap the bolt. Some head bolts I had to remove and clean off a glob of what looks like orange thread locker, which this might be the case with this one bolt. This might be just fine but I gotta make sure there's no coolant combustion gas oil mixing going on. Also gotta see if it starts up with a loud ticking noise when cold. It definitely runs rich when cold as the exhaust gases are burning my eyes. Next will be installing that wide band sensor.

Started it again and ran it for a while to see if any ticking noises would appear. This is a cold start. Sounds good to me. I'm thinking that lifter failed a while ago and finally let go of the push rod. Might need a new battery for it.
