Looking at this problem you have (like nailbender's wiped thrust bearing) has taught me some new stuff I wouldn't even have known to consider if I decide to pull my old flat tappet cam and go to a hydraulic roller which I will probably do at some point.
Yea' half a dozen machine shops and five R&R's of the engine and sets of bearings. Although the C4 to T-5 swap has slowed down the rate of destruction I'm now at 10 thousandths on end play on the crank again and will be sliding another new thrust bearing in shortly.
A lot more goes on than 99% of the machine shops would ever be able to figure out and at that point you are on your own. I feel your pain Tallguy and good luck!
