Take a look at that main and how its worn - you can see copper!. All of the mains were worn in this manner though this is the worst. No I know why they have to shut Geelong down producing stuff like this. 55000 kms and the thing is close to failure. Link to comment Share on other sites More sharing options...

But that main bearing wear is most probaby due to poor engine assembly, bad line bore etc. As I said, ALL of the main bearings displayed this wear pattern. This isn't something that happened by running a generic tune for an hour. The engine had a mere 55000 on it... Link to comment Share on other sites More sharing options...

Maybe 45 minutes. Backfired at about 4000rpm under WOT and bent that rod. Unlucky? Maybe. But it seems it's a bit of pot luck with the way these mass-produced motors are turned out.
