OK I'm not sure where this stands or what the answer is.......is the 3.5 a non-interference engine or not? Member "Crossman" who is currently selling his 2001 Proton advised this is an interference engine and now today while getting Kilby skids installed, mechanic looked it up in his latest "book". Says it IS AN INTERFERENCE ENGINE if 8th VIN digit is an "X".Help......
