background that may help:
- EGR was active during this sludge-fest
- it is more than 1/8" of sludge.
- the front of the engine (near the chain tensioner) is mostly dry (pict)
- the intake/exhaust manifolds were oily and wet
- the turbo housing was also oil covered
- the intake on the turbo had 1/2" of build-up in the 'valley' created by the compressed air outlet
- the wastegate was covered with sludge
- the turbo wastegate hose was very very loose on it's fitting into the turbo
- all turbo oil lines looked okay
- the valve cover gasket is a million years old and will be replaced
- the manifold bolts were quite loose (is there a torque spec? do they loosen over time? should they have threadlock?)
- there was also this nasty kink in the manifold gasket between E1 and I1. this will obviously get replaced
- the intake ports are horribly wet and sludgy ... as are the valves (from what i can see into them). Is there any way to clean them up?
- the exhaust ports are just 'sooty' and it doesn't really bother me.
Anyone have thoughts on the leak?
Any thoughts on cleaning it up (ports?)
Basically ... I want to eliminate all traces of this mess while i'm in here.
Thank you all!

I would be careful tightening the Manifold Nuts as the part of the Stud that goes into the Cylinder Head has only about 4 complete threads on it.
My Manifold Nuts were Copper. I never found a torque for the Manifold Nuts in any Manual but there is a torqe fot generic Cooper Manifold Nuts that have the same metric threads.
And, of course I forgot where on the internet I saw that; all I can remember is it was not a regular part seller but a Performanc Auto Part seller.
I also cannot remember if there is a direct shot at all of the Manifold Nuts that you could easily use a Torque Wrench.
If there was a lot of Oil in the Turbo charger Compressor side it could be the Turbo Seals are shot.
