Hi Robert. My name is***** will be glad to help you with this but impossible the way the site is set up for us to get this all in one reply since we have a 5 minute timer to send an initial response. So bare with me while I pull up your engine specs and information to give you accurate and complete information to help you out here.
1. The flange seals against the counterbore when the head is torqued. Therefor the liner protrusion has to be correct an in specs for all liners or flange failure and leaks will occur. Also the counterbores need to be cut and shimmed to obtain the correct protrusion and correct any imperfections in the block and checked for cracks. the liners marked for the correct protrusion an best clock position to get closest to specs on the protrusion.
2. answered in #1. closely machined tolerances, correct liner protrusion, and head torque.
3. No coolant in this area means a counterbore or flange problem most likely or potential cracked block. Most likely liner flanges not sealing due to bad counterbores and incorrect liner protrusion.
4. They are a slip fit on this engine.
Also verify the block deck is true and within specs before counterboring and shimming to bring protrusion into specs. Some machine shops will come out to your site to do the counterbores and provide you the shims. Be sure to install the liners in the best clock position " marked" by the machinist so the results are exactly what was machined per cylinder.
