Hi Guys,

I have R32 BUB engine in my Mk1 golf and it vibrates the whole car :O It is not not-drivable, but i can't see anything in the mirrors and the dashboard sounds like it's coming apart :)

So when I build the car last winter I started with a used Flywheel from a Passat VR6 and clutch, and i don't remember it being this vibrating. I then disassembled the car for paint and together with that I changed the cam-chains and bought a lightened flywheel with a Sachs clutch:
SACHS 3000384001 KUPPLUNGSSATZ VW GOLF

The VCDS don't show any DTC's and no misfires detected.

I fear that the flywheel/clutch/crank is out of balance :O Has any of you guys any experience with out of balance flywheels ?

It is four sure engine related, it follows RPM's, really bad around 3000, and then not as bad in high RPM.

Can anyone tell me how to troubleshoot on this? Can i use VCDS to something ?? Is it normal with a lightened flywheel to increase vibrations ? I really don't wanna pull gearbox of and put the original VR6 flywheel on if thats not the issue...

The engine pulls nicely, but could it be a cylinder is behaving badly ?

Any ideas is welcome....

Thanks

Thanks for Reply guys...

The mounts are brand new from Eurowise. When fitted the front munt I needed to really push the engine back to mount, maybe this could be the issue, I will look :)

Oh forgot to update the thread. Turns out it was the new Sachs Clutch that was not balanced prober. First I did was to change to standard flywheel and when i did I bought a new Reinforced clutch and got it rebalanced together with the OEM flywheel. Thats solved the issue. I them swapped back to the light flywheel and got that one balanced together with the new3 clutch, and no still no issue...

I've had every flywheel/clutch replacement balanced before installing. It's pretty surprising out out of balance new parts can be. :(
