posted of the same issue over on PPBB complete with a running commentary and pictures of what he was trying.
It starts here
http://www.ppbb.com/phorum/read.php?19,1551648,1551648#msg-1551648 but there may be a few more separate threads as the saga streatched over about 10 days IIRC.
Do not despair, read first and then consider the things he tried. It wasn't easy but your engine isn't wrecked.
