Another interesting Mercedes anomaly.
The Exhaust Seal part number is A000 053 09 58 which also fits various M121's in addition to the M127 according to the EPC.
If you order the part individually they are $7.03 each or $42.18 for 6.
The Intake Seal part number is A000 053 1958 which also fits various M115's as well as various M100's in addition to the M127 according to the EPC.
If you order the part individually they are $5.55 each or $33.30 for 6.
Total price for the complete I and R Valve Seals for the M127 if ordered individually is $75.48
If you order the M115 seal repair kit, A115 050 0105 for 4 of each (I and E) the price is $49.58 (you'll need 2 kits) and have 2 left over. Total: $ 99.16
If you order the early M100 seal repair kit A100 586 00 05 for 4 of each (I and E) the price is $62.90 (you'll need 2 kits) and have 2 left over. Total: $125.80
If you order the later M100 seal repair kit A100 586 01 05 for 4 of each (I and E) the price is $56.98 (you'll need 2 kits) and have 2 left over. Total: $113.96
So, as far as I can tell - at least according to the EPC, you can either pay$75.48, $99.16 or $113.96 for the same part number to do a complete seal replacement on a M127 motor.
The kits MAY contain other items but that is not clear.
All prices are from MBOEMParts.com.
These are genuine M-B parts from a M-B Dealer (Mercedes of Naperville, IL).
The EPC is our friend.
