Intake manifold sludge?

[memper]

Vertical mani where it meets the head has black crud.
Looks like an oil leak. Maybe dripping down from a leaky valve cover?

Also I do know for certain that the exhaust cover on the horizontal head is leaking some oil.

Does Chris sell gaskets? I couldnt find any on the site.

Get the "rubber" coated OEM valve cover gaskets, they last forever.

Mine are like thin metal ones with a grooved pattern embossed on them.

So my guess about the sludge around the manifold is from oil collecting is likely correct?

[Speeddog]

Those are the good gaskets, if they have a thin black rubbery coating.

Clean off whatever sludge is bothering you.
Clean the gaskets with 'carb cleaner' , same for the mating surfaces.
Confirm that the mating surfaces don't have any burrs or dings.
Reinstall.

See if it returns.

From what I remember they were not sealed in rubber. Unless it's so thin that I didn't notice.
