some people sais problem is between Turbo to Manifold
 
propably it will enought to change gasket
89-92 Turbo to Manifold
(http://www.mazdatrix.com/pictures/exhaust/turb2manS5.jpg)
 
because manifold has no cracks but between engine block and manifold there is a black smudge
propably that gasket time is over and it didin\'t work
 
Also what do think about ELRING CURIL T - universal sealing compound  for permantally hot service conditions?

I\'m not sure about the sealing compound, never heard of it, but thats definately a big blow you have there, speak to Grinder (he will be back on here Saturday evening) as he had a similar noise coming from one he owned.
