Is this that dreaded K-Seal?

Just finished getting the inlet manifold off and yep it had been one of the leak sources for the coolant and we now know why the coolant stopped returning to the tank:-







Notice the silicone sealant bodge. There was also a selection of different type nuts holdign the manifold in place so new nuts will be bought to fit the replacement manifold.







The hollow in the head between the ports is stained pink from coolant loss.







This is what was scraped out of the coolant gallery that feeds the jiggle valve in the inlet manifold:-







It's a granulure reddish stuff and I am not sure if it's rust from the inside of the steel coolant pipes or K-Seal or Radweld of something equally as horrible:-







However it now looks like I may have to remove the head to clean this gungy stuff out and perhaps had betetr remove the underfloor pipes to flush they clean and carefully check their internal condition for rust and pitting .................................................. .. hmmm might even be better off just fitting new S/S pipes. Will give this some thought.



Due to the damage to the plastic manifold have bought a TF 135 alloy one to fit in it's place along with new gaskets of course
