hi i have got a 90 with a 300 tdi disco engine in fitted a new half shaft to it tonight and thought id start her up and let her run for a bit started her up and there was a knocking i thought nothing if it and cracked on then after 15-20 mins it like it died then ran normal then did it again then bottom pully seized so turned it off within 5 seconds of this happening. should of checked the oil level!! anyway put oil in it and wound it over its just nipped is there any chance of saving her ???

not if it has seized internally even if briefly

hmm ohh deer new engine then do you think ?
