SOHC Posted October 26 Share Posted October 26 Those cracks are in a place that you could repair them, as they are seem to be with in the frost plug holes and and that fitting, a block seal would take care of them or you could weld them with a nickel rod, they cant really spread 2 Quote Link to comment Share on other sites More sharing options...

But I would just prefer to start with a none cracked block 2 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted October 26 Share Posted October 26 Back in the 80s dad worked at a place that owned a fleet of 6cyl holden utes. (Dad reckons they were unreliable trash,) one of them had a 202 black motor that threw a rod/punched a hole in the block. They found some clever welding outfit who glued the block back together. (I would presume the bore would have needed a sleeve) 3 Quote Link to comment Share on other sites More sharing options...
SOHC Posted October 26 Share Posted October 26 I brazed a hole up from a rod once, it has broken a bit off the bottom where the cylinder hung down into the crank cake but its still running 2 Quote Link to comment Share on other sites More sharing options...

I do need some spot lights I’ve got a good pair of chrome Lucas spotties you can have for postage, they’re the type that mount off a bumper. If you’re interested I can get a pic. 2 Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted November 2 Share Posted November 2 It's done now, but how fast did you run the drill when honing the block? Everyone seems to go too fast, which results in a too horizontal hone pattern. (Verses the 60° hone pattern which is ideal) If you watch a video of a Sunnen honing machine in action, the rotational speed compared to the up and down motion is a lot slower than the your average drill at full jandal. A pneumatic drill with the reg turned right down is a great way to sustain a lower honing speed 1 Quote Link to comment Share on other sites More sharing options...

Old lower voltage one has a lower base speed than the late 18V jobbies. 1 Quote Link to comment Share on other sites More sharing options...
