Yes Ireland, it will be fixed and hopefully about 500hp. All I an do is see what happens.

Have you seen a crank this bad or worse r32-25t? Just curious on your statement as I dont know the limits of a regrind on a crank.

Hi guys, This is a picture of an RB30 crank that has 1 connecting rod journal pitted slightly. Anybody know whats the limit for grinding a crank and also would you class the extent of this pitting.

Here is a couple of pics of the inside of the block from the sump side. I dont think the dent at the bottom will interfere with the piston skirt so I'm going to give a go at the welding and see where we go from there.

Thank you PLYNX, I was hoping someone had actually seen this done before. I'm a welder by trade myself and a welding inspector so I believe i have the ability and the knowledge to do it. Also I know a few welding engineers that will help with the composition of the welding rods required. Crack testing here we come.

Are you sure its fatal, crank is perfect, bore is perfect. Weld it up, add a conrod and we'll see how it goes. My only concern is where it will be welded is the area where the engine mount goes. Just have to heat, weld , peen and heat treat properly.

Hi, Just came across this RB30 block with a bit of an issue. Not much damage apart from the hole in the block, any ideas on what caused it? I'm contemplating welding the hole up and rebuilding it with standard rods and pistons to see how it holds out. RB30's are hard to come by where I'm from. Is it worth it, has anybody done anything like this to any other block?
