The issue with silicone sealants is that they are often inappropriate for the job. Unless formulated for use in contact with oil, they often refuse to stick (ditto for use with coolant, as I found out in Canada getting a water pump to seal in the dead of winter).
Worst case you get what happened to the 75 300D my brother had -- some idiot glopped a huge amount of orange silicone sealant on the oil filter housing, with the result that a lump peeled off and plugged the oil supply to #2 main badly enough it ate the bearing. The gasket is supplied with adhesive on it..... The service manual will specify the correct sealant and amount. Typically, if the gasket need sealing, it will be supplied with adhesive/sealant on it is a sealed package from MB, aftermarket may or may not. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
