ok heres the deal, ive got an ls with sleeves but in by my local machine shop. i put my swap in and i keep on losing antifreeze. i call a performance shop and they tell me that more than likely the sleeves are leaking. i jack my car up and take off the oil pan, windage tray, and oil pickup. i compress my system with air and slowly but surely water droplets form on the bottom of my sleeves.

have any of you guys ever heard of this and what can i do to fix this? is there some kind of miracle stop leak on the market? what have you guys done? this really sucks because i paid the shop 1300 dollars ans some odd change and this is what i got. they wont warrenty it. wtf im stuck and heart broken HELP!!!!!!
