88 k5.

[Ic88k5]

OK I have a couple questions about a k5 I recently picked up.., OK first one, is the starter was installed crooked an so now the flexplate has a dead spot on it and was wondering if I could replace it without having to drop the Trans and tcase? The second is the engine runs good no misses or anything like that, doesn't over heat but when ever i start it and let it idle it has white smoke coming out of the passenger side exhaust true duals with headers , it's not to thick but it's noticeable and has water dripping from it, doesn't smell like anti freeze I use 50/50, was told it could be a number of thing like valve seals, head gasket or clogged oil drain-back holes, fuel air ratio problem, weather change? But my luck probably head gaskets can't really tell if it does it when I drive it, but if I could get some clarification on the 2 problems that would be greatly appreciated
