TDI 1.9L 5-Speed Single Mass Flywheel (SMF) Proper Weight and Why

VW TDI ALH 1.9L Turbo Single Mass Flywheel(SMF) Weight. SMF from on a 2000 VW Golf TDI ALH 1.9L that had a Run-A-Way do to worn Turbo. Because the EGR valve was in-place the car was able to stop even though it was in full run-a-way, but the crank case oil that filled the intake flowed into the #1 cylinder, causing a hydrostatic lock. Once the locked motor was attempted to start the starter removed flywheel teeth. These missing teeth caused a dead spot on the flywheel in which the starter would fail to turn the flywheel.

It was determined that the flywheel/clutch assembly had to be changed and the #1 calendar cleared of crank case oil. The oil was removed by slowly turning the 19mm main crank bolt with the oil pan removed. At first, when i observed that the crank could not be turned completely, I feared that one or more of the connecting rods were bent or broken. But as I slowly turned the crank the piston rings compressed and allowed the oil to be forced out of the filled cylinder.

Then I moved on to replacing the flywheel. I though that a Ultralite 9lb SMF would give better MPG and faster acceleration times. So I purchased a Ultralite composite Stage 2 SMF and installed it. What I noticed is that the clutch pedal was soft unlike the 23lb G60 SMF with a Stage 2 Clutch, and there was a transmission chatter when that shift position was in neutral. I found that the 9lb flywheel does not provide better cold starts, MPG, highway speed, or acceleration times, and quickly wished that I had installed a G60 flywheel instead.
