You can have them welded and re-ground which should be on the machinists nickle
if he didn't follow direction.

Subject: [Fot] Oversize split seal for TR4 engine
I have had my share of machine shop disappointments over the years but this one
hurt. I had two stock crankshafts cryo treated and reground with the intention
of building a lower rpm motor using Larry Young's camshafts and replacing the
crank in my son't TR4 racecar. At the time the machinist I had been using went
out of business and I tried a guy that had been recommended by a couple of
Spitfire guys in my local club. Long story short, he screwed up the grind on
the scroll seal and overcut it. I put the crank in the TR4 and trimmed the seal
a little bit but the car leaks too much oil. Not very scientific, I know but I
was desparate. Before I start experimenting has anyone found on oversize split
seal, or split a seal on their own and could offer advice? I'd hate to throw
two cranks in the metal bin.
