With the pickup that blocked and noises from cold i'd be looking at the bearings before i went any further down the path of cleaning it up.

Good luck with it. I hone mine doesn't look like this inside but I'm not brave to look.
Have you checked the opening on the pcv Valve ? Was it blocked? There's a utube clip on here somewhere of a guy blaming all these sludge issues on the tiny hole in the pcv getting blocked and not letting the crank case breathe.
There would be a reason for it,oil doesn't just sludge up like that without help on a car that is regularly driven.
The only Engines i've seen like that were 1990 era Falcon Gas Taxi sixes,a guy had a workshop near my Brothers Engineering Business and he blamed Gas for the problems,obviously not the cause here.

Has anyone heard of sea foam?
If so was it any good?
Work good, but it would be like trying to piss on a bushfire in this case.

I have driven a vk on gas for many years and have never had the oil between changes look other than normal.
I was told that LPG is like almost 100 percent burn so no blow back gasses where as petrol is less and does have blow back.
When I removed the head for stem seals I could not see one bit of sludge/oil build up.
The old girl has been handed down to the next generation and still going strong.

Some oils lack detergents now days, always worried when people boast about changing oil and it's still gold in colour = **** oil no cleaning your engine.

To op you've opened a can of worms keep going now fingers crossed you have a win. Few 1000kms down the track will tell that

No argument,i've heard the same,only difference is i've seen 253/308 engines running on gas with stuffed heads,the aftermarket Heads with hardened valves were not up to the job.
The Falcon Taxis motors i saw had sludge everywhere,rocker cover,sump etc.,similar to the OP,.
I don't know if its the difference in burning temp of gas or the fact they can run 24/7 but the motors were a mess,cleaning the oil galleries would be the big problem with Re-Co'ing.

X2, I had gas on the Jeep for 8 years. I tore that motor down as it ran out of water and the insides were clean as.
