Aluminum 'Press In Sleeve' block warning This is to make the forum aware of an issue present with Press In sleeves as used in re-sleeved LS2,7, Warhawk and RHS engine blocks.
The use of an improvised cylinder ring (that uses no machined receiver grove) or a gas expandable ring as used by some head gasket companies can cause unwarranted effects to the 'press in' cylinder sleeves causing them to be pressed into the block and below the deck surface, potentially damaging the seating surface for the sleeves.
Traditional O ring with a receiver grove using a copper or graphite gasket has proven to be satisfactory, provided the depths of the groves are done properly.

Can you elaborate on this? I am currently running the Darton Dryliner in a LS7 block without any issues so far. I have rebuilt this block several times using various head gaskets ie. GM and Cometic. I have heard of some issues so i am all ears!?

You could I suppose torque plate hone the block with the ring and gasket installed, good luck with that.
