My ti M-Pack has a blown head gasket - why I got it cheap.
One of my other cars is a Daimler Sovereign S2 - read Jaguar XJ6 S1.
The engines in them are renown for camshaft cover oil leaks - THE fix is a well kept secret.
When the retainers are over torqued the material of the head is drawn upwards preventing the cover from sitting down correctly. This is usually followed by some PO tightening down the retainers further - increasing the leak.
The trick is to LIGHTLY countersink the threaded holes to remove the distorted material.
New gaskets correctly installed and covers correctly torqued - no leaks.
Hope that helps some one with the leak that wont stop!
