Darton question




Both sides of the thrust were heat discolored.
Has anyone seen this before in an LS1 buildup either with a Darton sleeve application, or in a regular application?
I'm not looking at the Darton as being the culprit, but more looking to see if it may have been an assembly error. I'm not there, so I can't check endplay, etc... But I'm just looking to see if anyone else has seen any sorts of issues.
Thanks.
