re: XJ40 rotors

Re the questions on rotors/steering rack.  Had similar problems with my 1988 
XJ-40.

a)  Rotors on this car tend to warp easily.  But they can be turned and there 
was a minimum spec (which I cant remember, but I think is stamped somewhere 
on the rotor).  However, new rotors are fairly cheap and its worth the cost 
just to put on new ones.  Mine kept warping after they were turned and were a 
pain.  Never regretted putting on new ones.

b)  Thought my steering rack was weeping also, but was wrong.  There was a 
slight weep from the fitting at the back of the power steering pump and also 
the rubber hose from the header tank.  The slight drip ran down the engine 
mount and was very hard to trace untill I degreased the whole area and kept a 
close eye on it.  At first glance, the fitting at the back of the pump 
appears to be a bushing with approx 1" OD.  In reality it is a more complex 
piece sealed by an O ring that takes on a set over time.  A new O ring solved 
the leak.
