Good evening all,

I an new to the e34 world, but I have been close to the e12 FirstFives bunch for several years. The cars in our stable include:
1979 528i, 198k miles
1998 740il, 65k miles (so nice it scares me)
and the new 535i, 5speed, lowered, bilsteins, chipped, 144k miles

It seems my flywheel on the 535i has the "famous" dual mass rattle. What are the chances that an e12 flywheel/clutch set will work? I have read that people use e28 flywheels and clutch sets. I just so happened to have a good 1979 528i flywheel and nearly new clutch set. Does the e12 flywheel have Motronic / timing pick up points problems?

I have an ittermittant coolant leak at the heater valve/aux water pump area. I cann't seem to narrow the leak down. Is one component more that likely to leak over the other one?

Thank for the help,
Chris
