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.
