In the TR6, the thrust washers are held in only by a ledge made by the 
fact that the main bearing cap is not recessed for the thrust washer. 
 In a word, there are only the upper halves of each washer, not a 
complete circle.  If there is any wear to the cap, there went the thrust 
washer, into the pan.  One ingenious fix, an old idea, is to drill 
 through the thrust washer half into the block, and then insert a very 
small brass dowel, one one either side, to fix the thrust washer and 
keep it from rotating..  The dowel is cut off even with the bearing 
surface, and will not cause wear to the crankshaft, but will let the 
thrust washer do its job without rotating.
