Hello. I am brand new. I didn't see this answered anywhere. I have seen lots of useful information about Trailblazers on this site, and I appreciate all of the valuable information. A few weeks ago I picked up a very clean 2002 Trailblazer with a bad engine. Apparently it was run dry and spun a rod bearing. The rest of the bearings weren't very good either. Anyway I am rebuilding it. The crank kit arrived and I realized you can put the main bearings in with the tangs going either direction in the bearing caps. Which way do they go? Should the top go the same direction as the bottom so the tangs are opposite, or the same side? I realize the caps are numbered and arrow goes forward. I just don't know about the bearing direction. I appreciate any help.
