Just reviewed service task 01-212 - removing installing top front cover off the 126 CD-Rom - 103 motor in my 126.
Two(2) different sealers are mentioned.
001 989 61 20 10 - seals the u-gasket in the corners
002 989 00 20 10 - used to coat contact surfaces of front cover to cyl. head
Looked at this sites PartsShop and found 5 different sealers that start with 001 989 as does the u-gasket sealer mentioned above. They range in price from $9.50 - $21.00. Did not find an exact match for the sealer # mentioned above.
Also found one that's close to the 002 989 mentioned above - it sells for $17.14
I realize that numbers get superceded, but for the moment, I'm confused as hell.
