Got some pics of my nada cam when I fist got it, ( somewhere) running on 5 cylinders with 3 missing lobes.
Top speed , about 50mph
I have heard that (don't laugh) Olive Oil heated up to the point where it's smoking and poured down the bores is good at freeing up stuck pistons.
just took it out because it was ejecting oil out under pressure from every orifice
I've found a snapped piston ring on the first one that came out...
Try soaking it in ATFOk well a few weeks on and the diesel soaking hasnt really helped yet.
