Looking for used engine 3.2

[tqtran]

freaky986 : If I can remember correctly, you can not boar the engine out. If I remember right the engine is not 100% metal, its part silicone(in layers) and boaring it out would damage the stability of it. Someone that has a tech book handle look it up for me cause I am not at home right now. I recall entertaining this idea in the past and was told that the engine composition would handle this. ToolPants any input here????
