Hey there,
I want to start by saying I am a newbie. And thanks to all your threads I have diagnosed several problems on my 98 Spyder GST. I wanted to address an issue I have to deal with right now. I was thinking I was experiencing crank walk. But upon doing further research I discovered that I more than likely was experiencing a harmonic dampener problem. I have decided that for now I will just buy a $150 dampener/pully at the dealer. Has a warrantee anyway.
My question is: Could the issues with the "crank walk" be related to the use of poor/inferior method of crank balancing from the original 2g design.
-Its sort of a "chicken and the egg" idea. I wonder if a motor came out of the factory with more accurately designed bearings and a proper balancing system (something superior to fluid balancers, or rubber dampeners) was applied, would a 7 bolt engine be just as good or better than a 6?
-Plus I think the reason problems dont occur more often than one might think with a solid aluminum pulley. Because of the weight difference and tighter weight center the engine relies on its internal balancing more to keep it smooth. Thus an engine that could be the victim of random circumstances could develop crank walk. And some do not.
-My Purpose is to see what your opinions are on these ideas and to assess the question: Can a 7 bolt engine be built to run as stably as a 6?
