A bit of dino sludge in my case after a few years is nothing compared to this ...

This is coked oil from the turbo. I did nothing else but switch from synthetic Shell Helix Ultra 5W-40 to non-synthetic Penrite HPR30 20W-60 to cure it.
As far as I'm concerned, synthetic oils aren't worth the risk.
1988 Carrera - 3.6 engine (with ITBs, COPs, MS3X) and a whole set of turbo body panels waiting in the attic.
Day job ...
