Crank Walk Adventures: Thrust Bearing Failure

It may be possible to determine the thrust washer orientation by pulling the oil pan, but I am not optimistic. But I will look into it.
Thrust washer correction requires crankshaft removal, which means engine removal.

Had my 2007 since 2009 with 13K on it now 123K. Beat the shit out of it on the dragon a few, maxed it out on the autobahn quite a bit (flew it to Germany), and ran it rough on the Nurburgring. It has served me well but I would have rather it actually blown that had this funky issue.

Man this scares me. I have an 07. Sometimes when starting the car the car has kind of a slow or erratic crank. I've been trying to figure it out, and in the service manual if everything with the starter and battery check out then it just says "check for excessive drag on the engine". I hope this isn't an early warning sign of a bad thrust bearing. Subscribing for updates.

Billman, will bypassing the clutch interlock solve this even if the thrustwasher was installed backwards? And please do keep us posted if theres a way to confirm correct installation.

Bypassing the clutch switch will always help, as it prevents any crankshaft rearward pressure during engine startup.
BE WARNED if you are not careful, the car can be started in gear and take off at 2000rpm. So if you do the bypass, be mindful.

Driver input plays a big role in this, especially under boost conditions. If your shift timing is not proper (you apply pressure to the clutch pedal while there is throttle input) it will accelerate the wear. It is also accelerated with a heavier pp, when coupled with improper operating technique.
The two combined driving forces cause the most wear, as does dry morning starts.
