hi, i have recently had grinding noises from my spitfire i bought a WEEK ago!! and did a simple test of pushing clutch in and found the crank pulley moved substanually forward when it was in?is this a definate check?and is the only option nw to replace bottom end and block??
think if you have 1/2" its more than just thrusters,even if thet have dropped out (very common) but if the crank has worn away its thrust face you need a new crank or get the faces metal sprayed and reground( not always successful but worth a thought) if themain bearing cap lugsare worn away by the crank then you can normally repair the bearing cap by welding a new lug on its face and fettling down to size, it only holds/stops the thrust from falling out,it takes no hard load,does little work apart from washer retention. if the crank has worn away the thrust washer location face then the block is stuffed unless you are a magician
you can get the sump off with the engine in the car to examine the main bearing caps .and crank thrust faces
