The engine should not be "eating flywheels". Was the flywheel replaced when the engine was built? Very few technicians understand the proper method of checking the flywheel for wear in the second mass, and few of those have the proper special tool from Luk to check it with properly.

The difference between 5 and 6 speed flywheels is enough to lock the drive train up when a 6 speed flywheel is used with a 5 speed tranny. That was one of the first bits of exchange that I learned with these cars. Its easier to use a 5 speed flywheel in a 6 speed trans, than the opposite, and the engine doesn't play a part in the exchange.

Finally, people have difference "balance tolerances". When I read that something has been "balanced" the first question I have is "to what tolerance"? The act of "balancing" can mean that someone removed one bit of material and the part was balanced. To me balance tolerance is .5 oz./in. measured at the largest OD of the mass. I trust no one to balance items, and thats why the same person that builds the engine from scratch, will also do the balance work. This is also why we balance the entire rotating assembly as it will be bolted together in the engine.
