Will report back when back on the rollers. Looks like it's where it kinda should be Link to comment Share on other sites More sharing options...

Just the usual immediate post build stuff like leaks etc? Edit: you said rollers, is he gonna do hub and roller while you're there?

Tom Tucker Donating Members 701 Member For: 5y 9m 9d Posted 22/03/25 09:19 AM Author Share Posted 22/03/25 09:19 AM Oh, sorry, meant back on the hubs. Nah, looks to be more serious. Engine coming out and being stripped down. Possible split bore 1 Link to comment Share on other sites More sharing options...

It's not a small task to fix that, look into options before you spend up big. Link to comment Share on other sites More sharing options...

Tom Tucker Donating Members 701 Member For: 5y 9m 9d Posted 24/03/25 12:40 AM Author Share Posted 24/03/25 12:40 AM Confirmed. Cylinder 1 split. New block inbound, with better bore thickness hopefully. 1 Link to comment Share on other sites More sharing options...

It could have taken the rest of the rotating assy with it. Link to comment Share on other sites More sharing options...
Tom Tucker Donating Members 701 Member For: 5y 9m 9d Posted 24/03/25 04:36 AM Author Share Posted 24/03/25 04:36 AM Yeah, apparently it was just bad cylinder wall thickness. It's unfortunate that two machine shops didn't pick it up. But realistically, a small frame turbo setup will always be more vulnerable from cylinder pressure at lower rpm Apparently cyl 5 is most common. Followed by cyl 1 & 6.
