Nasty suprise when doing Intake manifold seals

[Ronin]

When I replaced intake manifold seals on my 2.8 I found that the whole thing is caked in old sticky oil mixed with sand.. the seals were also perished

Cylinder walls are probably all scored now but I can't tell whether its taking any oil because the engine itself is hemorraging oil from camshaft seals....

Crank breather hose was also all caked up in oil which looked more like tar..
