Hi ATH,

Years ago I had an XW Fairmont wagon with a 302 Windsor (which I wish I'd never sold).

It trashed the key and damaged the keyway in the end of the crank under the cam drive gear. The garage I used at the time simply cleaned it all up (especially getting all oil off the crank end, keyway and pulley) and re-assembled with a new key and a Loctite product of some description.

Had no probs with it at all afterwards.

HTH, DL
