I appreciate you guys making a video from something that needed to be done to this car. At the same time we looking at some great content and learn from it at the same time.

Also worth mentioning that any time you mess with the flywheel or crank trigger you'll need to run a "Crank Relearn"/Misfire Monitor Neutral Profile Correction with a scantool or SCT tuner after everything is re-assembled.

Well, that verifies that I can’t do this myself.

[kingjames]

Should the crank relearn procedure be done after cranking the car first or before ?

[camyota]

I noticed he put silicone on the bottom side of the plate where it meets the oil pan gasket. Is this necessary? I don't remember there being any rtv on that surface other than in the corners.

If you cant do this by following your steps, better lay down the tools. This was a great Video, I will check out your others, I have a 2015 GT 6 speed been having issues with new clutch, I do want to ask It seems a lot of shops don't do a Crank Relearn procedure, once that fly wheel or crank sensor is removed. Do you perform the crank relearn procedure ? I will for sure check your other videos. Thank you for the personally I don't like having to take my car to some mechanic and trust them everything is done correctly. You make that possible with these type of DIY Videos much appreciated.👏

[DeJack]

Are these bolts torque to yield? Would that make tgem one time use?
