Nobody cared to check and or even feel that the liners drop in block with no force at all (we took them out with hand)not even talking about cutting the block. Hopefully Mr.Rawze didn't scare you but educated you like us all about repeating problems people do.

speaking of 150mm liners vs 152 liners,.. Mr. hag said something very interesting in this regard yesterday to me. he said that every single 150mm liner they have pulled out of an engine, the liner o-ring was pink in color, and that every 152mm liner they have ever pulled out of an engine, the o-ring was blue in color. -- they said they can spot what size liner the engine takes just by looking at the color of the o-rings, BUT-- they never take this for granted, they measure any ways.
