You need to test it. You'll need Stihl Test flange # 1118 850 4200, Sealing plate 0000 855 8105, Carburetor and crankcase tester
1106 850 2905 and Vacuum pump 0000 850 3500.
Or you could just take it to a dealer and let them do it.
The 4 Torx Head Bolts were snug, I just checked.
Honestly I probably could replace the crank seals cheaper than the dealer could test it. What do you think?
