Darton Sleeves I’ve just had Darton dry sleeves installed on a ls1 block and bored to suit a 4.155 piston. One area that concerns me is that when the sleeves got machined, the are where the sleeves meet each sleeve in the middle has been machined into the water jackets slightly in the course of fitting the sleeves.
The machinist and engine builder both seemed to think this was fine. To me I don’t know how it would seal properly. Now you have coolant also directly in contact with the sleeve sides.
It might be ok but I have no idea myself.
Any thoughts?

Are you sure it’s an ls1 block? And not an “ls” type block? Cause… if that’s the case the whole enchilada is probably trash.
