I recently replaced a head gasket in my 2000 Wrangler. I took the head in and had it resurfaced and had a valve job done at the same time. The machine shop said the head was warped and not cracked so it appeared as though I had lucked out, however I think I may still be loosing coolant. Is it possible the engine block surface is warped or the block itself is cracked somewhere. Im stuck and have the feeling this Jeep is going to cost me more money than it has given me in enjoyment so far. HELP!!!!!!!!!!!
