Re: Poll: Cracked 0331 cylinder head castings

Neither my past 2001 nor current 2000 XJ have suffered this problem, both having in excess of 100,000 miles on them. To be honest, I'm not sure which casting I have (don't know where to look to check), but neither one has any of the usual symptoms of impending head or head gasket failure.

FWIW, there are three sets of numbers on the manifold, reading from left to right: the firing order (clearly not it), another one starting off with a '4' that was half-buried under the throttle body, and a third set of numbers represented in three rows, the bottom one being '11156' or similar from what I remember. Can't really pull stuff to check right now, so any help would be appreciated.
