Message Blew cylinder #6 at a lapping day. Hole in exhaust valve, some pitting of cylinder head, and some scoring of cylinder wall. Photos attached. (I hope) [LL|http://i1112.photobucket.com/albums/k495/bwarthur/motor002.jpg] [LL|http://i1112.photobucket.com/albums/k495/bwarthur/motor001.jpg] [LL|http://i1112.photobucket.com/albums/k495/bwarthur/motor004.jpg]
Motor has 50K original miles on it. Block and head are stock. Upgraded add-ons (intake, turbos, exhaust).
What do you think -- rebuild with oversize pistons, new valves and maybe cams or just dump it and get a Stage 2 or 3 from Z1 or Import Parts Pro?
